Sir Good day Ang Harman kardon ko n avr151 5.1 ay gnon p Rin Ang problema on and off at tulad Ng pinakita mo s video ganyan n gnyan Ang problema, checked ko Ang BN65 connectors from PSU terminal #5, 6, 7, 8 & 10 ay wla voltage reading, sir hingi ako Ng suggestions Kung ano Ang possible n sira Ng avr 151 ko, thank you very much
Good day sir. For sure na reset mo na ang unit mo. Sir pweding gawin mo to. E unplug ang unit. Tapos buksan mo ang takip then e disconnect mo ung connectors CN20 ito ung red black and white. Supply ng main amp. Pagka disconnect ay e plug mo ulit ang unit at e power on mo. Kung nag on at meron ng display ibig sabihin ay nasa main amp ang sira. Isa sa power transistor or pre driver transistor ay shorted. Pero kung same psrin ang problem ay malamang sa PSU or audio processor/hdmi board ang problem
Saludos y muchas bendiciones tengo la falla de un Harman Kardon modelo AVR 2700 parpadea la luz de Standby pero no Enciende algun consejo ya revise toda la fuente de alimentacion y no consegui daño alguno midiendo con el multimetro .

my dea friend i´ve trying to get a hold od the service manual, since in the SMPS board i have resistor that´s burn out its postion its r990, i don´t know where to get them, i need help for this issue
Boss saan po ang puwesto nyo,? Kasi po itong amplifier kong harman kardon model no.avr 135/230 factory 2005 of july ,complete power sya pero walang sound,ano po ang sira nito?
Dasol, Pangasinan ang pwesto ko. Sir na try nyo nabang e reset ung unit? Pag ganito na ang case kalimitan may nakikita akong mga sirang capacitor, kaya hindi tumutuloy ang signal. May mga case naman na hdmi board (where audio processor is located) ang may problema. Mahirap kasing tukoyin kung saan ang problema hanggat hindi nada diagnose ang unit.
I have encountered with to AVR different unit. One is a change of a value resistor in the power supply, while the other was change value of resistor in the protection circuit of the main amplifier.
@@ozidarkside4141 If I'm not mistaken capacitor and change value or resistor. That is a couple of years ago... I forgot which specific parts in the board. Kindly reset your AVR by pressing Surr Mode for 5 to 10 second.
@@wamopa I did the reset process you mentioned, but it didn't work :( I gave it to a service that does electronic repairs, I hope they can detect it with a measuring device.
I'm getting the correct question, then you can fix this by putting appropriate size of wire connected to your capacitor going to the components which is connected to the capacitor.
@wamopa You have some image of The circuit of The capacitors? I undertand your answer, i have The smd capacitors but You recomend The normal component with his wire
@@aramisdejesustinocodiaz7566 Actually the PCB pattern or traces can be found in the service manual links provided the description of this video. You can reach me in my WhatsApp and Viber Apps for more assistance.

Naka reside nga pala ako dito sa Petal lagpas lang ng Hermosa Bridge (20 to 30meters ) from bridge if you are heading to Sta. Cruz Zambales. Makikita mo ung signage ko on left side of the road.
I had the reciever working many hours and once i forget something on it and it overheats. After that it started blinking. Turned it off, waited, turned it on and worked. After 15 minutes of operation its shat down again, and now it cant turn on in any case. I replaced the two 1kv 470pf caps on the primary, because one of them was burned, but that did not fix the problem. I replaced the caps on the digital board (the 5v ones) because the seem to leak, but the problem is still not fixed. I have jumping standby 5v voltage, like 2.5-3 volts when amber blinks. No info on the display. Its not the amp board. I want to check the temp sensors but i dont know what to do there. :/ its avr 270
Good day. I've experienced that problem before with some other model of HK. Did you try to isolate the main power for the power amps section? (CN20) base on the schematic diagram. If not kindly try. Once the connector was disconnected/ isolated, try to plug the unit to power. Once the display showed up. then you have problem in your Main Amp board. Did you try to manage to check the following: voltage regulator? IC97 - 7812A IC98 - 7912A IC99 - 78L24 If one of the voltage is missing/ abnormal, it will give you Amber light (System protect mode) Just in case you don't have schematic diagram.. please find below your service manual for your amps along the additional service bulletin from the manufacturer: elektrotanya.com/harman_kardon_avr270_370.pdf/download.html#dl servlib.com/harman-kardon/audio/avr-270-sm7.html?start= Just let me know the results. Cheers!
Bossing Kung hindi mo pa nasusubukang e reset ung unit mo ay pwedi mong gawin to. Reset Procedure: 1. Standby mode 2. Press the "Tun mode" key for a 6 to 10 seconds until “RESET” will appear in the Front Panel Display If the problem persist then may internal problem ang unit mo. May ilang unit ng Harman akong na encounter na ganito ang problema. ang problema kalimitan ay Power Supply at mainboard lalo na sa Main Amp section. Pinaka mainam ay dalhin nyo nalang sa Service Center
Halu,,help,, parehas na parehas ung sa akin na harman sa video mo sir,, na palitan ang tatlong capacitor,,kaso ganun parin,, walng display at naka stanby mode parin,, ne reset namin wala parin
Good day sir. Natry mo nabang e isolate ang power rail ng main amp. Pag hindi pa ay pakisubukan. Pagkataos mong e isolate ang power y etry mo ulit e power on ang unit mo. Kung nagkaroon ng display. ay may tama ang isa sa mga output transistor mo.
Hi. I have the same Amplifier Harman Kardon Avr 151, and I also have the same problem as shown in your video, red light blinking. I'm in manila. Can you repair my receiver. Let me know. Thanks.
Hello, Welcome to my channel. Why not, unfortunately at time is not possible because of covid. BTW i'm from Zambales. Far from Manila. Did you try to Factory Reset your AVR? If not kindly follow below's procedure: Unplug the power cable. Wait for 3-5 minutes. Then plug it back in, While in standby mode kind press and hold the Surr Mode button in the front panel for 5-6 seconds.
Hi, thanks for the reply. Yes I did try the reset option several times but no luck 😒. Wow Zambales is very far from where I live 🙄. I could send it to you via LBC once the ECQ has been lifted. Let me know if that would be OK with you!
Hello there! My AVR151 drops sound most of the times in any of the following scenarios: a) change of source b) pause and play of the same video This applies to all HDMI, ARC and Optical sources. What I have observed is, once the receiver loses sound, even the test tone is not working in the speaker setup menu. Once the AVR is switched off and turned back on after a few seconds, everything comes back to normal until either of the above scenarios comes in action mostly. Appreciate your help on this. Thanks!
Hi Jasim and Good day! Have you done the System Reset? If not please do follow below's procedure. 1. Press the front-panel Standby/On switch to place the unit in the Standby mode (the Power Indicator LED will turn amber). 2. Press and hold the front-panel OK button for at least 5 seconds until the RESET message appears on the front-panel Message display. NOTE: After performing a processor reset, wait at least 1 minute before pressing any Source Selector buttons. If you "DON'T HAVE ANY INTERNAL COMPONENTS FAILURE" like the one showed in this video. Sorry to say that you need to replace the HDMI board (processor /system controller) which is easily available upon order request at any Harman Kardon service in your area. Specially if you are in KSA, UAE and Qatar.
wamopa Thanks a lot for the prompt reply bro! I have performed the processor reset multiple times. But it didn’t work. I’ll check with the local HK service centre then. Many thanks again! Have a pleasant rest of the day!!
wamopa Is there any way to confirm the problem is with the HDMI board? I mean what could be gone wrong on the board or any specific components to be checked on the board? P.S: Will really appreciate of you can provide any reference diagrams as well.
@@jasimmuhammad8974 One way to confirm is to swap the HDMI board from other unit. Trouble shooting this type of AVR, you need an oscilloscope and other tools in order to diagnose the problem. Most common problem of AVR' at long run is the audio baseband network processor chip FS1230 (IC1105) BGA (ball grid array) This problem happened also in ONKYO. In my case I found some corroded/leaked SMD electrolytic capacitor in the HDMI board as well as in the Main Amplifier board. Sometimes reflow of smd components will help to solve the problem. I believe 2012 was the manufacturing date of these particular model. Usually the life span of consumer electronics now a days is 4 to 5 years. As requested please below the download link for the service manual of this model. elektrotanya.com/harman-kardon_avr151-230_rev.0.pdf/download.html
Hi praveen. If you have a friends working in KSA or dubai you can ask them to buy for you in one of their service center (By providing them the particular model of your AVR)
Hi po. Same situation din sakin, AVR151 "blinking orange light" Pina check ko po sa service center ng HK -Manila ang sabi digital board daw po. Pero diko pa natry gawin yung mga advise nyo ,check the speaker or wiring or resetting. May idea po ba kayo kung may nabibili na spare ng digital board? Mahal po kasi presyo nila sakin sa pagawa. Salamat po .sana mapansin nyo concern ko. 🙏🙏
Good evening. Medyo may kamahalan po talaga. Kung meron kayong friend or relatives sa KSA or sa UAE ay pwedi kayong magpabili sa service center nila doon. Paki try muna ung reset at kindly check kung may mga hibla ng wire mga speaker terminal ng unit nyo
Hi! I have the same problem with my AVR 151, light is blinking even when you do the surff mode reset, nothing appears on the avr monitor. Please kindly help, I am from General Trias Cavite. Thanks!
Hello, If not power supply, most of the problem is cause by a faulty HDMI board and sometimes Main amplifier section. Did you try to your AVR to any Reliable Electronic Repair shop?
@@wamopa Sorry for late reply, no I did not send for repair to any electronics shop. It was just lying in room, By the way, san ba shop mo baka puede dalhin ko na lang dyan sau for repair.

Sir good day, I have Harman kardon AVR 151 the problem is when I try to switch on, it doesn't continues and dies instantly on its own, when I have it checked with technician, he said that the problem was with the transistor 65E6280 HAG325. MAY I ASK IF WHERE IS THIS AVAILABLE? THANKS AND PLS ASSIST FROM LAGUNA
Good day. With reference to the service manual the complete part number is IPW65R280E6 located in the power supply area. Q901 location in the pcb. You can find the part in Laz@da and sh*pee.
I have another problem with HK AVR4000RDS after switching ON the set and selecting any source it takes nearly 20 - 30 minutes for the sound to come ON. Thereafter it works till it is switched OFF. noted preamp O/P from opt amp are muted. what does it trigger to unmute.
Hi Mohan. Did you notice if the MUTE indicator on FRONT Panel display is lit? Kindly check Power ON/OFF mute circuit (Q558, Q559, D405, D406, R570 and R571) for components failure and change value of resistor. BTW don't disable this circuit. It's help to protect the speaker by eliminating a strong pop up upon opening and closing of power.
Hi, @@wamopa Thank you for the tip. The Power ON/OFF mute Q558/559 stage is working. No sooner the amp is powered I can feed a signal to main amp/s and it works. It is the O/P from IC716,717,718 &719 in the Processor board that gets muted for about 20-30mts and comes ON automatically.
Hi Mohan, With reference to the schematic diagram, by removing temporarily the below x’stor (e.g. Q721 for Front speaker) you can bypass the muting. (Make sure that these x’stors are okay.) Q716, Q717, Q719, Q720, Q722 and Q723 I believed you already check the below list of x’stor, specially the pull up resistor connected to VCC Q718,Q721,Q725,Q724,Q730 and Q731 (x’stor with build in pre biased resistor) Check also these x’stor near IC 201 Q222, Q223, Q224, Q225 and Q226 Lastly if still the same and other components were okay and still the same problem there is possibility that IC 201 is the culprit. Cheers!

Thanks sa info' Sir.
Brother same issue with my AVR as well, I have check the caps they are ok. Even base board caps are ok. so what else do you want me to check? if I remove this heat detect resister this unit will work?
Hi brother, Have you tried the Factory reset of your AVR? by pressing the Surr.Mode button of your AVR 5 to 6 seconds? (while standby mode/ with amber LED) If the caps are okay, kindly check also following: 1. Speaker binding post terminal for any possible short circuit of strand of speaker wire. 2. Check the output transistor with Multi meter for any defective. 3. Check for any cold solder on the main amplifier board. These are the things that will cause the AVR to turn into system protect mode. Don't remove the heat detect resistor, otherwise the system will not work and will turn itself into system protect mode. BTW what is the model of your AVR?
@@wamopa Brother thanks for the instructions, I'm bit new to electronics. I tried to do processor reset, but didn't work. then I check caps, they are also good. I'm having the same model AVR 151. please let me know how to check out put transistors with an analog multimeter. appreciate your help.
@@lahirucp Though I believe you're good in electronics, Please find below my answer. For the service manual kindly download from this link: elektrotanya.com/harman-kardon_avr151-230_rev.0.pdf/download.html Be noted that the Power Output transistors of AVR151 are Darlington type, With 70 ohms built in bias resistor. For PNP Transistors 1. Set your Analog Multimeter to Ohmmeter X1 Ohm Scale. 2. Connect the Negative Probe (Black) to Emitter and the Positive Probe (Red) to the Base. The needle should deflect to the right side, reading less than 100 ohms. 3. Now invert the probe connections to the Emitter for the Red Probe and to the Base for Black. The Needle should not deflect. • If the results are the same as above, your Emitter-Base junction is OK. 4. Now we will be testing the Base-Collector junction. Connect the Red probe to the Base and the Black probe to the Collector. The Needle should deflect to the right, resistance usually is not less than 100 ohms. 5. Invert the probes again, Black to the Base and the Red probe to the Collector. The Needle should not move. • If results are the same as above, your Base-Collector junction is Ok. 6. Connect the probes to the Emitter and Collector (probes may be inverted), a reading above 1Kohms indicates a working transistor. For NPN Transistors 1. Set your Analog Multimeter to Ohmmeter X1 Ohm Scale. 2. Connect the Negative Probe (Black) to Base and the Positive Probe (Red) to the Emitter. The needle should deflect to the right side, reading less than 100 ohms. 3. Now invert the probe connections to the Base for the Red Probe and to the Emitter for Black.

Connect the probes to the Emitter and Collector (probes may be inverted), a reading above 1Kohms indicates a working transistor. Detecting Defective Transistors 1. If there is no resistance between any of the pairs during test (needle goes all the way to the right) for all the steps. The transistor is shorted. 2. If for all the steps, no needle deflection occurred, the transistor is open.

Good day po. Sa tingin ko na system reset nyo na ang unit nyo. May posibilidad may problema sa firmware need ng update. O kaya naman ay may problema sa Audio Processor/ HDMI board, usually cold solder sa chip. Isa ito sa problema hindi lang HK ganon din sa Onkyo at iba pang home theatre.
Good day po. Baka nais nyong sabihin ay kung pano e connect ang Sound ng TV to AVR po. Kung tama po ako sa tanong ay: Option 1: from Audio Out ng TV (located at the back or side) connect to your AUX/CD in ng AVR using RCA connector po. Then from source/input select nyo AUX/CD. Option 2: from HDMI out ng TV, (Use HDMI cable) then connect nyo po in one of the HDMI input ng AVR nyo. Then select kung anong HDMI port from your Source/Input. Incase walang Audio Out ang TV you can use Headphone jack kung available sa TV set nyo.

Then plug it back in, flip the power switch back to ON, then hold the Surr Mode button in the front panel for 5-6 seconds. Your AV receiver should be back to life. Option2: Connect your receiver to your router with an Ethernet cable (CAT5 or CAT6 with RJ45 connector). Using your computer, determine the IP address of the AVR 170/1700 on your local network. You can do this by logging into your wireless router's web interface, or by using a portable software utility from nirsoft : www.nirsoft.net/utils/wnetwatcher.zip download and install in your laptop or computer hit F5 in your keyboard to scan the network. You will find IP address e.g. (192.168.xxx) of Harman Consumer Group under the column “Network Adapter Company” Type the IP address of your AVR 170 into a web browser on your computer. If done correctly, you will be looking at the Harman Kardon web interface for the receiver. Click the Choose File button and any small file, e.g. a small txt file. Now click the Upload button.

I am having a AVR 240 and the small Transformer got failure Please let me know the small Transformer output voltage of this ?. This AVR 240 set is working with 120 volt..Thank you in advance(part number ULVER.CLT5 J033ZU. trans sub)
Based on the service manual of your AMP, the output voltage of this small transformer is 12v-0-12v AC. This transformer supply the 5v standy for the CPU and supply for the relay RY94. Incase you need your service manual/schematic diagram please find below the download link. www.vintageshifi.com/repertoire-pdf/pdf/telecharge.php?pdf=Harman-Kardon-AVR-240-Service-Manual.pdf
Dear sir I am Binoy from india... I am expressing my immense thanks and gratitude to you for given the answer about the volt of Harman 240 subtransformaer....I am deeply thanking to you.. as per your guidance I did replace of the transformer but still it is not working . I feel the reason for not working is because of my poor knowledge I given 230 volt connected to this AVR instead of 120 Volt. Can you tell me is the same reason my AVR is not working or any other reason ...I am humbly requesting your guidance and support...Thank you again🙏💐
@@mathewbinoy4144 Your most welcome, Since you already replaced the small transformer. It means that the old transformer is okay, just return back the old one. 1st kindly check if 5v Standby is present in the pin 3, and Pin 1 (should be 12 to 15V DC) of 7805 ic (IC94) if not check the fusible resistor R905 it should be 10 Ohms, you should get 15v dc from the side of D901 & D961. So that you can find easily those components and it's location kindly download your Service Manual/Schematic diagram. please find below: www.vintageshifi.com/repertoire-pdf/pdf/telecharge.php?pdf=Harman-Kardon-AVR-240-Service-Manual.pdf 1st give me your feedback and results for the above query in order to proceed to next step.

Good day. Sa tingin ko na System Reet mo na ung unit mo. Kung same tayo ng Amp. Unit, kung nakastandby mode at kulay orange din ang led. Ang unit ay nakasystem protect sya. 1. Maaring may problema ka sa isa sa mga output x'stor. 2. Pwedi ring may problema ka sa HDMI board/ Audio Processor. To check kung may problema sa amp section. Subukan mo ngang bunutin o e isolate ang power connector sa SMPS side CN20 +VCC (45v) -VCC (-45V) Kindly unplug muna ang Unit from Mains, Then e plug mo ulit sa power. Ngayon kung ang amp mo ay gumana. It means na may problema ka sa Main Amp section mo. Kindly check din kumg may mga lumubong capacitor at change value resistor.

Sir kaya nagkakaganito ang Amplifier ay meron syang nadedetect na problema sa loob ng amplifer. Kaya bago pa magdulot ng pinsala ay nag si system protect sya. ito ang problema ng Harman Kardon mostly pagkatapos ng 5 to 6 years na ginagamit natin. Habang tumatagal ay pahirap ng pahirap e power on yan. Pag napapagana mo sya napansin mo ba kung lahat ng channel ay gumagana? To test pindutin mo lang ung TEST button sa RCU or remote ng AVR mo. Ngayon kung may isang channel na walang sound ay try to disconnect lahat ng speaker mo. then check mo kung may short sa isa sa mga terminal ng speaker mo, baka may maliit na hibla ng wire ito ay makaka apekto sa system. Kung wala ay sundan mo nalang ang mga sumusunod: I assumed ay familiar kayo sa electronics? paumanhin kung nasabi ko yan. Mostly ito ang kalimitang problema ng AVR na to. Paki visual check nalang lalo na ung mga capacitor. May similarity ang diagram na to sa model mo (wala lang suffix na (S) sa dulo ng modelo. Location Digital Assy.

Sir naka system protect po yang AVR nyo. Pag more than 5 to 6 years po e check nyo ung mga capacitor na nag leak (kung may background kayo sa electronics. O kaya naman dalhin nyo nalang sa maaasahang technician.

e check mo lang ang isa sa mga amplifier section. e check ung mga resistor for change value at kung may ESR meter ka check mo ung mga capacitor, anyway kahit visual inspection ay kuha nayan. Isa pang isyo sakin ay ang puldown resistor na binanggit ko sa Digital board. Good Luck sa Amp mo.
Good day, Did you try the system reset? If not please find below. Resetting the AVR : Power off the unit, unlplug the power for 3 to 4 minutes then plug it back in. Place the receiver in Standby mode (press the frontpanel ) Standby/On Switch so that the Power Indicator turns amber). Press and hold the front-panel Surround Mode Button for 5 to 6 seconds until the RESET message appears in the display. NOTE: After performing a system reset, wait at least 1 minute before pressing any Source Selector buttons.

I had the reciever working many hours and once i forget something on it and it overheats. After that it started blinking. Turned it off, waited, turned it on and worked. After 15 minutes of operation its shat down again, and now it cant turn on in any case. I replaced the two 1kv 470pf caps on the primary, because one of them was burned, but that did not fix the problem. I replaced the caps on the digital board (the 5v ones) because the seem to leak, but the problem is still not fixed. I have jumping standby 5v voltage, like 2.5-3 volts when amber blinks. No info on the display. Its not the amp board. I want to check the temp sensors but i dont know what to do there. :/ its avr 270
Good day. I've experienced that problem before with some other model of HK. Did you try to isolate the main power for the power amps section? (CN20) base on the schematic diagram. If not kindly try. Once the connector was disconnected/ isolated, try to plug the unit to power. Once the display showed up. then you have problem in your Main Amp board.
Did you try to manage to check the following: voltage regulator?
IC97 - 7812A
IC98 - 7912A
IC99 - 78L24
If one of the voltage is missing/ abnormal, it will give you Amber light (System protect mode)
Just in case you don't have schematic diagram.. please find below your service manual for your amps along the additional service bulletin from the manufacturer:

Boss bago lang sa channel mo
Tanong lang paano naman po kapag sa harman kardon hk3700 Auto shutdown?
Bossing Kung hindi mo pa nasusubukang e reset ung unit mo ay pwedi mong gawin to.
Reset Procedure:
1. Standby mode
2. Press the "Tun mode" key for a 6 to 10 seconds until “RESET” will appear in the Front Panel Display
If the problem persist then may internal problem ang unit mo. May ilang unit ng Harman akong na encounter na ganito ang problema. ang problema kalimitan ay Power Supply at mainboard lalo na sa Main Amp section. Pinaka mainam ay dalhin nyo nalang sa Service Center

Hello there!
My AVR151 drops sound most of the times in any of the following scenarios:
a) change of source
b) pause and play of the same video
This applies to all HDMI, ARC and Optical sources. What I have observed is, once the receiver loses sound, even the test tone is not working in the speaker setup menu.
Once the AVR is switched off and turned back on after a few seconds, everything comes back to normal until either of the above scenarios comes in action mostly. Appreciate your help on this. Thanks!
Hi Jasim and Good day!
Have you done the System Reset? If not please do follow below's procedure.
1. Press the front-panel Standby/On switch to place the unit in the Standby mode (the
Power Indicator LED will turn amber).
2. Press and hold the front-panel OK button for at least 5 seconds until the
RESET message appears on the front-panel Message display.
NOTE: After performing a processor reset, wait at least 1 minute before pressing any
Source Selector buttons.
If you "DON'T HAVE ANY INTERNAL COMPONENTS FAILURE" like the one showed in this video.
Sorry to say that you need to replace the HDMI board (processor /system controller) which is easily available upon order request at any Harman Kardon service in your area. Specially if you are in KSA, UAE and Qatar.

Is there any way to confirm the problem is with the HDMI board? I mean what could be gone wrong on the board or any specific components to be checked on the board?
P.S: Will really appreciate of you can provide any reference diagrams as well.
@@jasimmuhammad8974 One way to confirm is to swap the HDMI board from other unit. Trouble shooting this type of AVR, you need an oscilloscope and other tools in order to diagnose the problem.
Most common problem of AVR' at long run is the audio baseband network processor chip FS1230 (IC1105) BGA (ball grid array)
This problem happened also in ONKYO.
In my case I found some corroded/leaked SMD electrolytic capacitor in the HDMI board as well as in the Main Amplifier board.
Sometimes reflow of smd components will help to solve the problem.
I believe 2012 was the manufacturing date of these particular model. Usually the life span of consumer electronics now a days is 4 to 5 years.

I have another problem with HK AVR4000RDS after switching ON the set and selecting any source it takes nearly 20 - 30 minutes for the sound to come ON. Thereafter it works till it is switched OFF. noted preamp O/P from opt amp are muted. what does it trigger to unmute.
Hi Mohan. Did you notice if the MUTE indicator on FRONT Panel display is lit?
Kindly check Power ON/OFF mute circuit (Q558, Q559, D405, D406, R570 and R571) for components failure and change value of resistor. BTW don't disable this circuit. It's help to protect the speaker by eliminating a strong pop up upon opening and closing of power.
Hi, @@wamopa Thank you for the tip. The Power ON/OFF mute Q558/559 stage is working. No sooner the amp is powered I can feed a signal to main amp/s and it works. It is the O/P from IC716,717,718 &719 in the Processor board that gets muted for about 20-30mts and comes ON automatically.
@@wamopa nope the mute does not light up in the display. It shows the selected source ready. Sound from Rec out can be heard.
Hi Mohan,
With reference to the schematic diagram, by removing temporarily the below x’stor (e.g. Q721 for Front speaker) you can bypass the muting. (Make sure that these x’stors are okay.)
Q716, Q717, Q719, Q720, Q722 and Q723
I believed you already check the below list of x’stor, specially the pull up resistor connected to VCC
Q718,Q721,Q725,Q724,Q730 and Q731 (x’stor with build in pre biased resistor)
Check also these x’stor near IC 201
Q222, Q223, Q224, Q225 and Q226
Lastly if still the same and other components were okay and still the same problem there is possibility that IC 201 is the culprit.
Cheers!

BTW saan galing nga pala ang unit nyo? Kasi pag hindi bili dito sa pinas hindi tinatanggap sa service center. Ang kalakaran ay bayad ka ng 10k php as membership in order to repair your unit.
With regards sa service center. Sorry wala akong alam dyan malapit sa area mo. Pakitingin nalang sa mga sagot ko dito sa tread nato ang service center ng Harman kardon
Ganito ang gagawin natin.
Sa tingin ko ay hindi mo pa nabubuksan ang ang unit mo. E unplug muna ang power ng avr. Subucan mong e isolate ang 45 -/+ supply.
Pagkatapos ay e plug sa power ulit. Pag nag start at may lcd diplay ang unit. Ibig sabihin. Ang problema ay sa main amp Section.
Kindly give me an sms to guide you accordingly you reach me by whatsapp. My number is in the description.
@@wamopa Yun ang challenge, this unit I bought from Dubai last 2017. I recently asked a local repair shop and the tech' himself went "lutang" trying to comprehend what I was describing him about an HK ARV161... Actually, malapit lang ako sa Beyond Innovations service ng HK dito sa QC. pero kung ganun pala ang kalakaran nila sa repair - eh baka ipamigay ko na lang ito AVR ko to anyone who wants to salvage parts from it. Thanks sa info' Sir.
Brother same issue with my AVR as well, I have check the caps they are ok. Even base board caps are ok. so what else do you want me to check? if I remove this heat detect resister this unit will work?
Hi brother,
Have you tried the Factory reset of your AVR? by pressing the Surr.Mode button of your AVR 5 to 6 seconds? (while standby mode/ with amber LED)
If the caps are okay, kindly check also following:
1. Speaker binding post terminal for any possible short circuit of strand of speaker wire.
2. Check the output transistor with Multi meter for any defective.
3. Check for any cold solder on the main amplifier board.
These are the things that will cause the AVR to turn into system protect mode. Don't remove the heat detect resistor, otherwise the system will not work and will turn itself into system protect mode. BTW what is the model of your AVR?
@@wamopa AVR 151, can you tell me how to test transistors with analog multimeter
@@wamopa Brother thanks for the instructions, I'm bit new to electronics. I tried to do processor reset, but didn't work. then I check caps, they are also good. I'm having the same model AVR 151. please let me know how to check out put transistors with an analog multimeter. appreciate your help.
@@lahirucp
Though I believe you're good in electronics, Please find below my answer.
For the service manual kindly download from this link: elektrotanya.com/harman-kardon_avr151-230_rev.0.pdf/download.html
Be noted that the Power Output transistors of AVR151 are Darlington type, With 70 ohms built in bias resistor.
For PNP Transistors
1. Set your Analog Multimeter to Ohmmeter X1 Ohm Scale.
2. Connect the Negative Probe (Black) to Emitter and the Positive Probe (Red) to the Base. The needle should deflect to the right side, reading less than 100 ohms.
3. Now invert the probe connections to the Emitter for the Red Probe and to the Base for Black. The Needle should not deflect.
• If the results are the same as above, your Emitter-Base junction is OK.
4. Now we will be testing the Base-Collector junction. Connect the Red probe to the Base and the Black probe to the Collector. The Needle should deflect to the right, resistance usually is not less than 100 ohms.
5. Invert the probes again, Black to the Base and the Red probe to the Collector. The Needle should not move.
• If results are the same as above, your Base-Collector junction is Ok.
6. Connect the probes to the Emitter and Collector (probes may be inverted), a reading above 1Kohms indicates a working transistor.
For NPN Transistors
1. Set your Analog Multimeter to Ohmmeter X1 Ohm Scale.
2. Connect the Negative Probe (Black) to Base and the Positive Probe (Red) to the Emitter. The needle should deflect to the right side, reading less than 100 ohms.
3. Now invert the probe connections to the Base for the Red Probe and to the Emitter for Black. The Needle should not deflect.
• If the results are the same as above, your Emitter-Base junction is OK.
4. Now we will be testing the Base-Collector junction. Connect the Black probe to the Base and the Red probe to the Collector. The Needle should deflect to the right, resistance usually is not less than 100 ohms.
5. Invert the probes again, Red to the Base and the Black probe to the Collector. The Needle should not move.
• If results are the same as above, your Base-Collector junction is Ok.
6. Connect the probes to the Emitter and Collector (probes may be inverted), a reading above 1Kohms indicates a working transistor.
Detecting Defective Transistors
1. If there is no resistance between any of the pairs during test (needle goes all the way to the right) for all the steps. The transistor is shorted.
2. If for all the steps, no needle deflection occurred, the transistor is open.
@@wamopa Thanks Brother!! I'll check and let you know..
Hello sir same problem po. Binigay lang kasi to sakin ng mother ko, matagal po hindi nagamit na stuck lang. Magkano po kaya paayos nito?

Hi sir i think I have same problem with your avr.. my avr151s was unable to operate well.. after started, a few seconds would be turned off and started to blink an orange light. May I know if you accept an home service?
Good day. Yes you are right. For time being I am in the progress of building my shop. So I am not accepting any job right now. Probably I will start and resume my work by september this year. By the way my new location would be somewhere here in Dasol, Pangasinan...
Hi sir . Where ir your location po ? Same problem with mine 😢
Hi Sir, paano po kapag nagdedevice sleep?
Good day po.
Sa tingin ko na system reset nyo na ang unit nyo.
May posibilidad may problema sa firmware need ng update. O kaya naman ay may problema sa Audio Processor/ HDMI board, usually cold solder sa chip. Isa ito sa problema hindi lang HK ganon din sa Onkyo at iba pang home theatre.
Sir pano po ba I set up sounds ng harman kardon avr 151 sa tv
Good day po.
Baka nais nyong sabihin ay kung pano e connect ang Sound ng TV to AVR po.
Kung tama po ako sa tanong ay:
Option 1: from Audio Out ng TV (located at the back or side)
connect to your AUX/CD in ng AVR using RCA connector po. Then from source/input select nyo
AUX/CD.
Option 2: from HDMI out ng TV, (Use HDMI cable) then connect nyo po in one of the HDMI input ng AVR nyo. Then select kung anong HDMI port from your Source/Input.
Incase walang Audio Out ang TV you can use Headphone jack kung available sa TV set nyo.

Sir sinubukan mo na bang nag factory reset?
Unplug the power cable. Wait for 3-5 minutes. Then plug it back in, to ON, then hold the Surr Mode button in the front panel for 5-6 seconds.
can you fix the BCO Update please wait error for AVR 170 model
Option 1:
Turn off the switch at the back of your AV Receiver next to the Power Cable Input, then unplug the power cable. Wait for 3-5 minutes. Then plug it back in, flip the power switch back to ON, then hold the Surr Mode button in the front panel for 5-6 seconds. Your AV receiver should be back to life.
Option2:
Connect your receiver to your router with an Ethernet cable (CAT5 or CAT6 with RJ45 connector).
Using your computer, determine the IP address of the AVR 170/1700 on your local network. You can do this by logging into your wireless router's web interface, or by using a portable software utility from nirsoft : www.nirsoft.net/utils/wnetwatcher.zip download and install in your laptop or computer hit F5 in your keyboard to scan the network. You will find IP address e.g. (192.168.xxx) of Harman Consumer Group under the column “Network Adapter Company”
Type the IP address of your AVR 170 into a web browser on your computer. If done correctly, you will be looking at the Harman Kardon web interface for the receiver.
Click the Choose File button and any small file, e.g. a small txt file. Now click the Upload button. Dont' worry about what file you choose, because the operation will fail, and will reset or get the AVR receiver out of update mode.
Your AVR is back to life again

Bhaisaf, In my humble opinion it is a good quality AVR with the typical lifespan of 5 years from date of manufacturing. (but in my case 7 years with cooling fan added) Not with the HKTS210SUB/230 the subwoofer is poorly design and one of the difficult sub to repair.
The things that I don’t like about this company: They have, Unreliable and Poor Customer service.

@@wamopa All components are inside the pack and back side is covered with metal plate. During operation, due to heat, components damage, especially
capacitors leaks..there is no ventilation.
In SUB TS-11, Power supply is Transformer. But other components frequently fails. Only sound quality is there, but components don't have long life, quality less components..
thanks Po...
@@sunildevaraj7555 Bhaisaf your amplifier is easy to repair. The production date of your Sub is more or less 2008 at this life span, you need to decap (change all the electrolytic capacitor) your sub woofer. Need also to remove the OLD silicon heatsinker compound and replace it with new compound. The amp of your sub is CLASS D the design has the highest efficiency

Sir kaya nagkakaganito ang Amplifier ay meron syang nadedetect na problema sa loob ng amplifer. Kaya bago pa magdulot ng pinsala ay nag si system protect sya.
ito ang problema ng Harman Kardon mostly pagkatapos ng 5 to 6 years na ginagamit natin. Habang tumatagal ay pahirap ng pahirap e power on yan.
Pag napapagana mo sya napansin mo ba kung lahat ng channel ay gumagana? To test pindutin mo lang ung TEST button sa RCU or remote ng AVR mo.
Ngayon kung may isang channel na walang sound ay try to disconnect lahat ng speaker mo. then check mo kung may short sa isa sa mga terminal ng speaker mo, baka may maliit na hibla ng wire ito ay makaka apekto sa system.
Kung wala ay sundan mo nalang ang mga sumusunod:
I assumed ay familiar kayo sa electronics? paumanhin kung nasabi ko yan.

Power off the unit, unlplug the power for 3 to 4 minutes then plug it back in. Place the receiver in Standby mode (press the frontpanel
) Standby/On Switch so that the Power Indicator turns amber).
Press and hold the front-panel Surround Mode Button for 5 to 6 seconds
until the RESET message appears in the display.
NOTE: After performing a system reset, wait at least 1 minute before pressing any Source Selector buttons.
@@wamopa If pressed that button it's coming to reset and immediately went to device sleep mode error
I have changed 3 capacitor and standby 5v is coming, then power supply is fine right
@@rajad1715 If you get 5v for standby that is correct.
@@wamopa what is the next steps to check, because same Orange light blinking
But the avr has no woofee
Hi, I believe you are referring to subwoofer. you need to buy a seperate sub woofer in order to add extra bass in your system.

Estoy pensando en comprar un amplificador como este problema a un precio bajo e intentarlo, es un amplificador precioso, pero, yo tengo un Philips desde hace muchos años, muchas horas encendido, se pone caliente, y ningún problema, si me sale, precio me pongo a ello, mas que nada por diseño y hdmis,
