- Thank you for watching.
Also the selection in the video where i’m talking about the transformer and i called it a power supply “sorry i didn't call it by it's name..i was thinking about something else'
enjoy the video.
For some cases” the (uF)micro-farad” can be increased” but you must be able understand the the circuitry/Schematics of that board or you will damage other components. And the Bridge I create at both broken points” I used Electrical tape and heat it up tight with a heat gun so their won’t be any contact point” just in case it rub against the board.
Until next time

Awesome video... I have one of these in the house and this video help me repair my amp... You rock dude 💪.
Delightful! I know you are glad you fixed it
Yes sir!!! I thought it was done for good.
you are a genius man!!!!!! thank you for sharing that! i have a car amp that only plays 2 channels the other wont play.
Thank you for your kind words. Your very appreciated on this channel please don't forget to subscribe and share. Amen
good stuff man best vid ive seen
Thank you so much I really appreciate that! Respect
CONGRATS on getting that to work again! Nice! @ 3:33 when you are pointing " this end and this end right here " I would think you should have put dual bridges so the other end did not have to rely on the board connection and so it would be exactly as the other end was with the bridge, That way your board would not be subject to boiling out that solider out as it did previously, ( especially since your cap installed is Bigger power than the old blown one.. LOL ) you should use the exact same part specifications when replacing stuff like that cap if you can - but hey, I have seen all kinds of crap installed in a amp lol. it's insane what folks will do to get a thing working, also it could have gone terribly wrong and toasted your little board again. Those kind of amps are funny, says 1500 watts and there no possible way it could even be 25% of that. I mean, if you really had a 1500 watt amp in there it would have way more that 4 Mosfet chips on that heat sink and everything would be massively over sized. I mean, car audio and house audio is different because of the power source being WAY more stable and continuous in the house BUT - this little amp is ridiculously small to even a zr120 LOL. You could do a solid upgrade on this one though the way it's laid out super easy though if you installed a small fan on the end of that heat sink to blow straight through those fins if you wanted to. it would dissipate heat MUCH better.
this amp may have broken the way you found it because of an Ohm load being too low for it. that little amp cannot hang with lower than the specs are and probably even a higher would make it last longer as the mfg is obviously a liar. when the Om load drops the amp will try to spew more current and the components will heat up like crazy.
that goo that you don't know what it is is the residue from the over heating, it's the STANK - probably cancer causing goo to boot. I don't care though it tastes awesome with a little Tapatio.
I liked this video man,
Thank you for appreciating my video and pointing out what could of been done better! we all are here to learn from each other and become stronger as one! "what your saying is making alot of sense and i respect you for that! Thanks again take care.
3:33 lol I know where you coming from.

@@jayflash1000 bro I got almost the same one mine is the 503 model same as that one with grey case. I need your help explaining a few things. I'll give ya my phone number so I can actually ask you some questions
@@jayflash1000 please bro I need your help
Toroidal Transformer thats good.
thank you for helping me understand the transformer name' i really appreciate that. i have a bad habit of misplacing words sometime' gotta work on that. lol
This is awaresome
Thank you
The burnt surface of circuit board should also be cleaned of the carbon to prevent any arcing or unwanted conductivity between traces. I use a dremel tool to do that.
Yes after i repaired it. I cleaned it after thank you for the advice . David.
Nice
Nice video tutorial very infomative thank you for sharing.... Nice cover... New friend from philipines
Jhunriel Juntilla thank you my new friend and your welcome I appreciate you see it informative and much more. Their more to come..
thats nice dud
Thanks Nicole
Really intrested
Thank you
so the bridged terminals, what did they repair?
Great question... a broken connection that was wet and peeling off around the speaker terminal area...
The Man Of Wonders I see! So that contributed to the lack of audio too! Cool! Thanks for the video
@@SteveFloresCoach yes sir .. Thank you and your welcome
hello, very nice tutorial, can someone on this forum maybe give me some advise plz, I have an eh600 technics hifi, but even when I turn the volume all the way up the sound level stays very low, any ideas that might help
Thanks
Maybe I could help!!! 1 Check to see if your wires are put in correctly, or not touching each other at the speaker terminals. 2 try to see if maybe you have a switch that is costing the problem, like the loudness or mono to stereo or sound selection and so on. If non of that can help you! then their a problem inside & must be looked at. That all I could do for now.
@JayJay Schnetler the technics eh series use class H switching rail amplifiers, if the volume from 0-40% ish is working correctly it would seem as if it isn’t switching to the high rail voltage or the high rail doesn’t have any voltage there, i would check the internal fuses if not its a qualified technician repair sorry, there are high voltages present inside so i advise against poking around in there unless you know what you are doing
Hi just a quick question i have a technical pro applified speaker vrtx12. And the problem is that as soon as i plug the speaker to power outlet and turn on the speaker it will automatically hear a really loud statik and thats all it does it just keeps hearing statik is there a way i can fix this issue?
Hello. Disconnect the battery for 5 mins and press the powerbutton down for 30 second .
Damn I wish I had your brains right now, I’ve got a pioneer 800 watt amp with power and ground but no output signal, I know for a fact it’s the output signal bcuz I tried a different amp and sub works. I also replaced fuses and rca and still no output signal. Could you give me any advice? I opened the back but I have no idea what I’m looking for, I’d really appreciate your wisdom.
Thanks man... try to see if you see things burned or bold like capacitors and then check broken solder points sometime the joints brake apart with cooling and heating for the transistors audio . That the best I could do without seeing the amp sorry.
i have the same thing but the subwoofer isnt working as well it is a subwoofer with a amplifier in it ther are no bolstered capacitors but there are 3 that arent straight and one is moveable could this be the problem?
Yes if one out of the 3 is moving that means it's no good you should change all of them.
Hey I have the same problem Gemini /As-15BLU I’m trying to fix it I got power but know sound how can you tail if the Terminator bad I couldn’t tell by the video
Hi sorry for the late reply been very busy. Ok try buy puting a mutlimeter on the speaker terminals and you should get some very low voltage to see if it's good. Also check your caps for the sound output section. Sometimes caps look good and go bad.
I bought pioneer private pro ax 720 amplifier but it is not giving sound to the speakers but when i turn on the amplifier there is a slight vibration in the amplifier. Plz tell how can i fix
Hi so when you bought the amp it came dysfunctional.? If yes! try these step-by-step. Check for boldes capacitors'(replace them) check all audio transistors,(if open replace them). check head jack to see if you get sound. If you get sound threw the headphone then step one and two could possibly
be the problem hope this help thank you for watching .
@@jayflash1000 thanks brother
1500w !!! not even if it was struck by lightning, how these manufactures get away with the highly inflated ratings is a mystery! the output transistors and size of the transformer say otherwise... around 100w rms per channel i would guess
lol funny isn't it? I don't see how they get away with it either. LOL so many companies do it though. makes me laugh.
Not even 100 watts more like 20 watts
Well I will say the same, but it’s a little tricky with these models of technical pro. I got the model HB3502U and it has balllllzzzzz.
I did some digging and it’s as if all models ending with (U) is well built. Yet technical pro doesn’t advertise these models on there website, only the shitty old (BT) models. I have 2 of them. Only 1 has actual power. N there’s no specs on these models only the weak ones with Bluetooth
I say în a cliping mode it will go 2×41 w rms
I just bought a tkl digital equalizer and it is outputting a static pulsating sound I can barely hear the music when turned all the way up any idea what could cause this it's brand new and I'm having trouble returning it it's a tkl t2531
Hi thank you for watching and asking for help. Ok yes I heard of this equalizer... being that it's brand new" let's try this first check to see if their no loose wiring. Make sure it has a good ground connection"(very important for clear sound). if that doesn't work! try the eq alone with the amp no mixer or other volume control. Check the wires!!!
@@jayflash1000 oh man thanks for responding definitely subscribing I'm going to check now and on the ground it's painted should I sand and re screw it back other than that all wires are good and the board looks good nothing that I can see and I've tried it by itself still a still a pulsating white noise sound this thing is brand new just got it and it's dead on arrival if I turn it all the way up I can hear the music threw the pulsating sound but barley I've tried balanced and unbalanced trying the ground now
@@rockman49er ok understood!!! Yes for all device make sure the grounding is connected. Fix the ground and remove the paint. This could probably be the problem And thank you for subscribing.
@@jayflash1000 ok I removed the paint and nope it's not the problem I made a short video should I upload to my channel will you check it out I'm going to upload it now should be ready in a couple hours because my internet sucks lol 😆
Well I guess your not going to check my video I knew this was to good to be true 😔 😞
Hey i sont know how else to get a hold of you. But i had a quick question i have a technical pro rx504 1500w and the digital fluorescent sound spectrum display isnt working i was hoping you might no the answer or could point me in the right direction please and thank you
Hey. Well to be honest It could be a number of things. First try the out put line that gives it power if the power is running good then check the board with the display. Most of the times the light burns put. If it's that just replace. Hope this helps
@jayflash1000 Hey, thank you for replying to me. I really appreciate it. Ok, I'll try to do that. But you're probably right. The display probably burnt out. I've been looking non-stop for a display for it. It's non extinct, not even technical pro has it. Anyway, that's why I reached out to you. Maybe you knew something I didn't.
@@user-rc6lc2fp4t no problem that what we here for. If you can't find the light use led lights they last much longer
@@jayflash1000 I will thank you
I have a technical pro 1500 amp H1502UrBT and when I press the power button the Bluetooth light alone comes on and nothing else happens
What's causing this and how do I repair it? Please
Hi ok check the fuses usually technical pro comes with 2 fuse lines... if that doesn't help just hit me back up.
Hy I have a problem with my 250 watts amplifier 5.1 channel ,2 channels are working fl and fr the other channels are not working
Hey... it sound like you might have a problem their!!! It's hard to tell.
what going on without me seeing inside of it! But you could check to see if you have fuses for the speaker terminal" also try to see if your have broken solder point around transistors Because something of the heating and cooling that goes on, Hope this helps
@@jayflash1000 thanks for the help
Plz help there is no sound on my amplifier It's Omega karrote Av 971kA
Hi check for blown capacitors, or bad transistor Or broken solder connections. Start with and get back to me.
The music on mine works then stops working… how can I fix it? Help thank you
Hi how long does it play for ?
@@jayflash1000for about 5 minutes sometimes 3 then it stops
@@guadaluperivera5268 it could be the broken solder connection or the transistors. If u live in new york I could check it out for u
@@jayflash1000 yes I live in New York City
1500watts @70% THD
That’s one dirty interior, are these technical pro any good, because they are reasonably priced.
they are worth it. I have a LZ-3000 about 15 year old and still works great and easy to work on for cleaning and repairs. the preamps are the best I say.
why did you removed the capacitor
It was no good, had to go like the wind!.
@@jayflash1000 how did you check it
@@jayflash1000 i have an amplifier but i dont know where the problem is
@@pipographerproduction2773 by seeing the boldness on top of the capacitor.
@@pipographerproduction2773 what wrong with it?
boss paano ayusin db amplifier may power pero no sound.thanks
Im a bit confuse.
hii
Suman Gupta hello
I mean capacitor

1500 w ? That is a joke for sure. You cant have that power, not with that transformer. If you have there 100w be happy for it... But judging how the diameter of transformer look, you have there 2× 50w rms.
Your right.
