MSI R7 370 2GB - help in diagnose and so on
Hello every one.
I have decided to write on this forum because I hope you can help me solve problem with my graphic card. I have to stress that electronics is not my profession yet. However, I keep try to learn it.
Diagnostic: The computer starts correctly, but the screen is black. Computer doesn't see card (it was verified using second graphic card).
Measured resistance:
SFC x4 (probably power supply of gpu) 0ohm
SFCx1 (probably power supply of memory) 25 ohm
1RO (probably gpu controller) 68 ohm
2R2 (probably memory controller) 107 ohm
LR47 (probably pci express or it is only 12 line) it starts from 0 and increase slowly to 4k ohm
Electric potential:
SFC x4 about 0V
SFCx1 about 0V
1RO about 0V
2R2 about 0V
LR47 12V
Moreover I have measured resistance for MOSFET (left side form power of GPU) and it looks fine.
First 3 (from top) are the same: G1 is about 8,8 ohms and G2 is about 74 ohms.
Last one is inverted by 180 degrees and G1 is about 8 ohms and G2 is about 40 ohms
The resistance was marked on the photo.
I haven't got idea what I should check now.
I have second one graphic card. It is that same, but 4GB memory. There I have some misses components.
C2610, C2507 and c2506 (I have tried to desolider this one but it crashed). I know that it is a capacitor 0201 but I dont know it values. I think that they are the same. Mabye someone know capacitance and voltage (I think that voltage is 10V)?
At the end if you preffer you could answer in you official language I will translate it.
