Hi everyone!
Hope you're all having a great day, and thank you very much for stopping by and taking the time to read this post to help me with my parents' Samsung TV.
My issue: No backlight.
Model: QE82Q70RAT
Type No: QE82Q70RAT
The TV was already serviced by Samsung once under warranty for the exact same issue, but six months after the fix, the backlight went out again. Now, Samsung is asking for nearly the same price as a brand new TV to fix this with the same 6-month guarantee.
So hopefully, I can fix this cheaper.

Please help sir, this board does not turn on because VSYS_OUT is 9.2v, I compared it with a normal board VSYS_OUT is 10.2v, I have replaced the PQ101 and PQ102 mosfet and BQ 25700 which is known to be good, but the results are still the same, thank you
VSYS_OUT 9.2v
Meter in resistance mode auto range 6M ohm ok

I just got in my hands one Macbook pro A1706. It was originally not turning on (only 5V 0,2a on all ports (and 3 ports were restarting ampmeter when connected)
I've replaced one CD3215C00 IC and now macbook is fully working (20V and charging fine)
There is only 1 issue that one USB-C port is taking 20V but 0A (after replacing CD3215 it was fully working and i was charging macbook on this port) but then it just turns off (ampmeter) and started with only 20V 0A.
There were some broken pads under CD3215 but i've recreated them.

Hi all,
as subject line says, I have a laptop that reboots after 30 minutes. Investigation leads me to believe that is due to intel ME as it happens everytime after 30 minute from boot, it just turns off, no overheating, nothing weird.
I found a lot of information about cleaning ME like this [URL]https://winraid.level1techs.com/t/guide-clean-dumped-intel-engine-cs-me-cs-txe-regions-with-data-initialization/31277[/URL] and this [URL]https://github.com/corna/me_cleaner[/URL]

Hi,
anyone able to provide the service manual for old plasma Panasonic TX-P42ST50E?
It turns off almost immediately (0~5 seconds after pressing the on/off button) and starts flashing the red diode 6 times.
I disconnected the left-hand side board (SC?, both the ribbon cable and the power cable to it) and also another ribbon going to bottom left board. Then the led signal is 8 flashes. According to service guide to another Panasonic plasma it would mean the left-hand side board is faulty. But I'm not sure it 100% applies to my model.
I checked that board for any obvious faults...Today, 06:59 AM -
