Asus GL552VW Rev. 2.0 Error 43

[DanielDacko]

Hello everybody, I am having problems with this board, it came to me literally half burned and after everything i changed, it gives me error 43 in device manager for the Nvidia gtx950m.

Here is complete confirmed burned and replaced part list:

IT8995E with a hole in it, changed and reprogrammed with several different files
PU9201>APW6001 along with PR9218 2.2Ω
PU8401>APW6001 along with PR8405 2.2Ω
PU8901>BQ24780S
PU9300>RT8248A along with PR9303 2.2Ω
PU8301>RT8248A along with PR8312 2.2Ω
PU8700>TPS51285A
PU8600>RT8248A along with PR8602 2.2Ω
PU9101>RT8815A along with PR9103 2.2Ω
D3107
PD6001


After this intervention, board came to life, but with error 43 in device manager, GFX voltage was/is 0.900~V

I changed the Nvidia graphics chip with another one, from board revision 2.1, old one was N16P-GX-A2, new one is N16P-GT-A2, couldn't find adequate drivers for it, so I flashed bios from board revision 2.1 because of the different vbios files in it just to try and see what happens. Bam, same error 43. I am kinda lost now, don't know what to try else. I have only boardview and another donor board with revision 2.1. Any help would be appreciated.

Thanks in advance,
Daniel

Ok, found short on PL9300>+FBVDDQ, 0.0Ω to ground, i assume this is voltage for video memory according to the boardview. Injected 5.3A but my lab psu goes only to 5A max before switching to CC, so now the board receives 0.03V and 5.3A and nothing heats up.

Any suggestions?

Removed the video memory and the short is gone. Replaced it with new memory and got voltage on PL9300>+FBVDDQ which is 1.37V, but again the same error comes up in device manager. Somebody?

There are 2 memory voltages, check for both.

There are 2 memory voltages, check for both.

Which are?
