Looking for Tongfang GM5TG0O schematics

[TimmyTurner]

Hello, would anyone have the schematics and/or board view for the Tongfang GM5TG0O (aka XMG Core 15 M21, Avell A70 MOB, Mechrevo Z3 Pro, among others) or a similar model?

I'm trying to debug an issue with the webcam module. Actual camera module and eDP cable both replaced already, but issue persists (glitched image, faint LED indicator, perhaps a power issue?). Having the schematics and/or board view would help a lot...

Hi all, my first post here. I was recommended this place, I've got a recently acquired x230i tablet running BIOS version 2.51 (GCET91WW). Some sort of supervisor password is set and I cannot access any of the secureboot etc settings. I've dumped the bios (both chips) with a CH341a and verified the dumps. I tried the autopatcher to no avail. Attached are the files, in a drive link as BadCaps wouldn't let me upload .bin's. Any help with this would be fantastic and much appreciated. The laptop boots fine, and posts to bios.

Hi all,

I have recently picked up this Dell OEM Nvidia GTX 750Ti 2GB Video card. Its an old card I know but still wanted to get it working if possible. The problem is the following:

- Put the card in my testing motherboard and start running Heaven benchmark
- Benchmarks seems to run smoothly up until half way then the motherboard completely shuts off immediately
- Try to start it again and I get a slight move from the PSU fan - a clear short
- A little troubleshooting later I find one shorted Mosfet - Replace them both - short is gone
- Put the...

So, it seems I've bricked a pretty expensive laptop by removing the windows key and not reading the bios chip correctly in the process. I have managed to flash back a corrupted bios, can someone have a look at this bios and try repairing it, currently the laptop boots to the windows logo turns of after 3 seconds tries booting again after 2 seconds then 1 until its flickering the windows logo.

I currently have a friends laptop that went blank while he was watching something. It powers up but no screen onboard or external.
If the battery is connected the power light is solid, but if I try with only the powersupply connected it flashes (might point to something?)

I have tried the most common troubleshooting to no avail, and there doesn't seem to be any obvious short anywhere on the board.
I can do more basic/common repairs like replacing components but if it needs anything like programming chips I do not have the equipment for that and I hope it isn't a bad GPU....

Hi everyone, i got a Alienware Area 51M-R1 that recently stopped working after downgrading the bios from 1.5.0 to 1.3.2. When powering on the laptop with the charger plugged in it does not post, fans don't spin and the keyboard doesn't light up either except the power button logo.

The logo shows a green light for a few seconds and then goes off for a second and keeps repeating for about 4-5 times. After that i get 2 red flashes followed by 1 blue flash which keeps repeating. This code usually means cpu failure but i can confirm that the cpu works because i tested it on a other system...

Hello. I am asking you for a hint on how to solve the problem with my touchbook Panasonic CF53-2 standart model. After setting up the BIOS, the laptop displays the wrong image until Windows loads. (More precisely, it displays, but distorted, instead of the Panasonic image immediately after turning it on, it displays what is in photo #1 in the attached file) Then the image appears when Windows starts loading and then there are no problems with the screen until the reboot. If you enter the BIOS, just a black screen. If you connect an external screen, the image on it is the same as on the built-in...

HI I have a lg-27ul550 monitor which has a strange issue - it flashes on then goes black - I cant seem to see an image on the screen with a flashlight. Occasionally it does work and during one of these times I put the brightness down and it ran fine for hours - I tried a factory reset and problem came back until I could get to the point where I could put the brightness down again. At one point I remove the power brick and ran it from my bench power supply and I noticed that it consumes nearly 3 amps with the brightness at about 80% - this is above the monitor specs which makes me think the the...

Hello everyone, ASUS FX505GT, dedicated GPU is shorted dead, I would like to disable it completely to activate only integrated CPU graphics.
Any ideas? I was thinking to start by removing L8700 and L8701 so +NVVDD wont power the GPU, and maybe editing BIOS to disable it and also eliminate the possibility of fans going full speed and that kind of weird behavior.

Is this possible? Any help would be great!

Hey everyone. I recently acquired a PS5 that is not turning on (no beep/power). PSU is good and there is no shorting on the 12V rail.
It came with a Gen3 SSD installed so I feel that things went down hill for the previous owner when it was installed. F7003 was blown but there was nothing shorting to ground. I replaced the fuse but still no power (new fuse is still good for now).
When connecting it to a bench power supply, it only pulls 10 mA (doesn't spike when first connected).
I noticed that there are a couple capacitors missing from the Vcore power regulator (pictures attached)....
