Hello everyone,

The TV won't turn on (no power, no LED,). All voltages are present on the motherboard. The CPU is working and is getting warm.

This is a common issue with this model. If the eMMC is faulty, the TV will either go into a reboot loop or not turn on at all.

does anyone have the EMMC dump file?


Model: Sony KDL-55W805C
Mainboard: 1-980-805-31
EMMC: SK HYNIX H26M52103FMR
Display-Panel: T550HVF06.0

Hello friends,
On this motherboard, there is a broken connection between the RAM slot and the CPU.
However, it works fine with onboard RAM only — everything runs well.

The problem is: when I shut down Windows, the screen goes black but the system keeps running.
I have to power it off manually using the on/off button.
When I turn it back on, it works normally again.

I’ve tried many BIOS files from forums and other sources, but only the original BIOS works correctly.

I would like to thank in advance any friend who can help me patch...

Good afternoon, I have this machine and I can't install Sense. When I run the software, the message "This model is not compatible" appears. I've read that this is because the model name in the BIOS says:
PHN16-72-99PA.
It should say:
PREDATOR PHN16-72-99PA
Could someone help me change the model in the BIOS or tell me how to do it?
Thank you very much in advance.
Model: PHN16-72-99PA

I'm rather new to repairing electronics, i do know the basics of most components but never actually repaired a PCB, but i want to change that.
So, i bought a faulty Sonos Play 1 speaker with the intention of finding the fault, and replace the damaged part.
Well, i did find the fault, i replaced parts that i thought caused the problem, but no-go.

The problem is a pulsing power supply, when i connect the mains to the board and hook up my thermal cam i see R306,307 and 308 getting warm, but i assume that's normal.
But, whats is not normal is the pulsing of resistor...

Hi guys,

This is my first post! 🚀
I have no idea what I’m doing, but I’m learning by trial and error.

I’m currently working on a Dell Optiplex AIO 7490—one of a bunch of AIOs that mysteriously failed to POST just a few days after the warranty expired. The original issue was that the PC worked fine until it was rebooted, after which it got stuck on a black screen (no backlight), with fans spinning at normal speed and a solid white power LED. Forcing it off by holding the power button would just cause it to switch on automatically and get stuck again on...
