Can you make a video on how to connect Sony dav tz 145 to moniter ?
These cables will help in that: ua-cam.com/video/pgAfY9uuFfI/v-deo.html
Is there any way attach optical audio board to Sony tz 145 dvd home theater which has not having optical input for 5.1 audio?
You can, but results won't be impressive. Optical port requires a fully digital amplifier (like DAV DZ350 is a fully digital amplifier), if you use an optical to analog converter, audio quality will get ruined, instead use good quality RCA cables.
@@M-DIY 🙏 Thanks brother!
The portless space named cn500 near the digital optical port is where the fan should be connected.
I didn't have a connector for that.
@@M-DIYyou just modify the connection..simple
@@edwin2963 I needed to be able to control the fan speed as per my requirement, that's why I used an external adapter.
@@M-DIYOk I understand
So far how's the fans working out???
I've got an overheating issue mostly at vol 23 upwards
Perfect! No heating issues are there at all.
@@M-DIY well then let me apply what I just learnt😁
Sir, mere pas ye sysytem hai, wo 30 minuts chalne ke baad low volume par woofer ya dusre speakers (ghar ghar)krackling noice karne lagte hai jese radio me awaz ati hai, aur kuch der baad me project pe chala jata hai, please kuch hel kariye
Overheating issue hai. Cooling fan lagalo pehle fir check karo. Agar fir bhi protect likhke aata hai toh Ram IC badal waalo motherboard ki kisi technician se. Shayad amplifier IC bhi damaged hogi aapke case mein kyonki cracking sound bhi aa rahi hai toh vo bhi badalni padegi.
@M-DIY Which liquid you use to clean?
99.9% Isopropyl alcohol
I wanted to see and make a fan power adapter for my Sony amplifier. My amplifier fan is not working .But I can't find the video in the description nor in the channel. Can you share me one if it's a part of another video or anyone else's video which is reliable?
You are the first viewer who's actually interested in the power adapter that I made for controlling the fan speed. I have not edited the video for this yet, but in case you really need it I can upload it sometime later on.
@@M-DIY I mean i need it. I have Sony DAV-DZ 151KB and the amplifier fan is not spinning anymore. I am worried now that it might get heated and i have been keeping myself form turning it on. I decided to open it and cool it myself rather than get it repaired in future when any problem arises due to heat. That being said, i can't/ won't force you.
I found a fan with a regulator on amazon but only two reviews on it said the regulator is not working as it supposed to do. I will prefer now to create myself one. Again i can't force you; but will still keep an eye if you upload it later on. Thanks a ton for quick response.
@@M-DIY Quick update. I tried to connect it in PC in 'SYSFAN' and found it not working. Purchased a replacement fan from a local shop and attached it with previous fan pins via connecting the wire since new fan had different pins. I will enjoy it for now like this until i find some pretty reliable solution.
I'll bring a video on this soon, just keep your amplifier cool until the video comes and you can build a proper regulator.
@@M-DIY Thanks a ton sir.
Both the fans r set as exhaust..🤔🤔 Wouldn't it be better if they were installed as intake.. 🤔🤔😎
No, amplifier heatsink is the hottest part in cabinet and its heat should be expelled out as soon as possible. If you put fans as intake, hot air will have to travel entire cabinet while heating all other sensitive components like ICs and capacitors which will reduce the life of the entire circuit. Even Sony has installed cooling fans in the same direction in their other home theater systems and in inverters too you'll notice same cooling fan setup.
Need help my friend I also have Dav dz350 in 2017 i have purchased.now the problem is on remote Tv hdmi option is not working I can't hear sound from tv , error is coming"no signal etc"otherwise all options are working.Can you help.
Check your HDMI cable
@@M-DIY thanks for reply i have check.Then contact to sony customer care, technician suggested me to change Motherboard.what i should do?what do you think.
@@sagarkadam_ Service center guys always want to replace entire motherboard to make $$$. Motherboard will cost you like 10-12k I guess.
First explain the issue again so that I know I am not misunderstood. You want to play audio on theater from your TV? You can either use RCA cables or optical cable for that.
@@M-DIY Thankyou for reply sir i want to use dvd player through hdmi cable to decode Dolby surround and other features. I tried using optical cable also but not working.service center said motherboard cost is $ 11100 .He is saying after that it is work.dvd disk tray is also not opening.Can you repair.....or i should go through service centre.if you do i m sure will save my money.
@@sagarkadam_ You want to play DVD on your home theater and have connected TV through HDMI for video right? Then it should play audio through its speakers and give video signal to TV until and unless it specifically tells unupported dvd format which is unlikely.
Sorry I am not a professional so I can't repair it for you. There is a guy on UA-cam who repairs all Sony home theaters. He is in Maharashtra maybe you can call and ask him? He will repair it for pretty cheap price.

Isme fan lagana zaroori ha kya
Life badti hai fan lagane se, zyaada tar amplifiers mein laga hota hai, usmein bhi pehle lagke aata tha but badmein company ne lagana band kar diya.
Mera pass dz 350 hai usme mod chenge nahi ho rahe hai wo chalu to ho raha hai par chal nahi raha hai
Most probably RAM IC ka chakkar hoga. Poora motherboard company 8000 mein badlegi. RAM IC badal waalo, 1000-1500 mein kaam ho jayega. Pehle check karlo ki koi capacitors toh leak nahi hai naa.
a very good idea though seem to have very little knowledge about the device you were working with, instead of using extra power supply for the fans you should have just used the already provided fan ports on the main board close to the sub woofer port which is controlled by the system and provides a smooth 12v dc for the fan. that's the port I have been using in all my Sony dz series for my clients. otherwise you are good
I was aware about those fan ports because Sony actually used to provide cooling fan installed in this home theater initially, though they stopped doing so later on but I didn't have connectors for those fan sockets on PCB. Also that socket was meant to drive one fan not two so I was worried about overloading it. However the most important reason I used a separate power supply was to be able to control the fan speed using a speed controller. During winters, 8000 rpm fans are too loud, especially when I am recording my voice for UA-cam videos, so I needed to be able to slow them down just enough to decrease noise while ensuring sufficient cooling. I didn't want to make it too complex otherwise I could have made automatic speed controller for fans too using a thermistor, but I was short on time and I had to finish all this within a day. I may do this in another video if I get time.
Kindly help locate the fan ports
Hello, what an educative post. What's the port code?
@@chrisodhiambo4132 cn500
@@modrique_ace can it support a 12 volt fan?
Bass boosted hai. Kya aur bass loud pe khrab hoga kya...
Loud volume aur base pe zyaada heat karta hai, uske liye hi cooling fans lagaye hai.
@@M-DIY bass boosted hai kya..
@@crownyrush nahi
@@M-DIY bass level 6 pe rha to volume 26 kiya to bass kharb hota hai. Kya
@@crownyrush nahi, full karke bhi bass distort nahi hoti.
Power supply me 12volt nahi aa raha hai
Fan connector mein check kara?
Sir ye overheat ke वज़ह se protect me chla जाता hai kya ya koi or problem है protect me jane ka?
Ram IC kharaab hone pe bhi protect mein jaata hai ya fir saare speaker connect na ho tab bhi aisa aa sakta hai.
@@M-DIY sir mera amplifier 1 घण्टे चलने ke बाद ye issue आता jb volume 28 se उपर करते hai तब आता है or player बहोत heat ho jata hai sir to me kya kru fan add kru jese आपने किए है ya कहीं repair ke liye de दूं
@@Dventures-07 Toh fir overheating ke karan hi protect error aara hai aur yeh achi baat hai. Ek fan laga lo usse solve ho jayega.
@@M-DIY ok sir thank you so much ❤️
Bluetooth ready dikha raha hai but connect nahi ho raha hai
Kisi aur device se connect karke dekha?
A good DIY but English language could have been better
I can add English subtitles if you want. Will that help???
