lotas thank you for the help! Taking the pics took too much time today. Tomorrow I will try to check the resistances. I have also found the exact boards at this site - unknown to me. You or Diah know about it? Numbers on the 4 boards match: https://www.taobao.com/list/item/545233842385.htm

I'm currently working on repairing a malfunctioning Sony TV model KD-65XE7005 with the mainboard 1-981-926-21. I would appreciate your assistance with this issue.
Upon powering on the TV, the Sony logo appears for approximately 3 seconds, after which the backlight remains lit, the screen remains black, and nothing else happens. The TV consumes around 55W initially and then drops to 35W. The indicator LED remains solid white. It doesn't respond to the remote control. When attempting to update the TV using a USB dongle, the dongle briefly flashes but nothing else happens.

I have a really weird problem, this motherboard was working normally, someday it just started and all fans were running but didn't want to post, tried resetting bios, checking CPU and it was getting warm tried external gpu, flashed bios with programmer, but same problem.
Next day after several attempts the board goes into protection mode, no more staying on, I turn on the PSU fans starts directly turning, it used to not start until I press the pwr button, now it starts directly and fans spins, and shuts off after 3 seconds sometimes less, then won't start again unless I unplug the PSU and... -
Hello together,
I am hoping for some tips here to repair a notebook.
The notebook has following issue:
After starting the notebook it shut down after a few seconds.
Sometimes it is possible to enter the bios but then after, another few seconds it shuts down also.
The time until shutdown varies slightly.
What I've tried so far:
- cmos cleared
- removed all components that are not essential for motherboard testing including keyboard and touchpad
- ram exchanged
- same behaviour with power supply or battery... -
Hello guys. I have a legion 5 17ach6h with Ryzen 7 5600h and RTX3060.
It was working perfectly fine but the cpu was overheating so i decided to replace thermal paste. I bought one from local hardware store and replcaed. it looked fine then the fan started to spin at the full speed after about 1 minute and then immediately shut off after 10 seconds. Then I though if i have done something wrong, so i cleaned up everything with IPA and put new thermal paste. but the issue was still there. After that, I came across this article where he had similar issue and he was able to solve it by replacing... -
So I have this Sony VJF152C11N ( Board Number : DA0HKDMB6D0 ) which came to me with no charging issue. The Charging IC was getting hot so replaced it.
ISL88732 replaced with ISL88731 and also the lower mosfet PQ59 ( NTTFS4C10NTAG ) with a similar N channel mosfet. Now the Charging is fine with 15.7 on BAT+ line but the new problem is that laptop boots till sony logo and then shuts down when battery is connected ( With or without AC adapter )
What could be causing this is a non compatible IC or FET or poor soldering or some kind of shorting?
