Hello,
I received this machine which starts, but no video (nor external) and no USB activity...
One CPU voltage fluctuates, 1.08-1.29V; all the others are stable.
It is UMA version, I think CPU core voltage fluctuates; on the small coil.
Heated FCH and CPU, no result.
Also changed DDR without success. CPU is APU, soldered on the board.
Looked for BIOS update, but (as usually) this model is not listed under download section...
There appears only C855D-12W which seems to have different BIOS update.
I then searched and saw that C850D-117 seems to have closer BIOS dump; being same model PSCC2E.
Comparing backup (uploaded) with this one, PLCBX8.FD results to be correct dump.
However programming BIOS didn't change anything...
As it is AMD platform, I suspect BGA chips.
Does APU dies before FCH, or vice versa?
Board model PLABX/CSABX UMA & DSC REV:2.1 appears as Pegatron10ABX into BIOS dump.
The machine came in complete, not opened in other service.
Any idea, before trash it?
Thanks in advance,
Vali.
