Hi I wanna start by saying this board was heavily damaged. when i got it it was completely dead. What's been replaced so far that had corrosion. u1900, u8030, u7400, q7320, q7321, q7310, q7311 and a few capacitors around u7400. I get backlight but the screen it came in with is cracked and the HDMI port doesn't work the area around u9750 had corrosion as well. I will order u9750 when and if I get a chime.
I'm not running it long because i believe the u5870 chip might not be working as the fans haven't spun even after waiting 60-90 seconds. I have 2 working 820-4924 that take a while for the fan to spin. but im uneasy about this chip I would say I turn it on just long enough for the screen to energize. maybe less than a minute or two
PPBUS_G3H - 12.59v
PP3V42_G3H - 3.42v
PPVRTC_G3H - 3.3v
PP5V_S5 - 5v
PP5V_S3 - 5v
PP5V_S0 - 5v
PP3V3_S5 - 3.31v
PP3V3_S0 - 3.3v
PPDDR_S3_REG - 1.65v
PPVCC_S0_CPU - 1.78v
ALL_SYS_PWRGD 3.3V
CPUVR_PGOOD_R 1.78V
Things I have tried:
1) Connect a mouse and it does flash and then its solid.
2) I can see that the screen starts out dim then gets brighter as if it was booting but I'm not sure because its cracked badly
3) I also believe the keyboard to be defective as i tried on a working board and it wouldn't boot with the keyboard in question.
