    [SOLVED] 820-3115 Liquid damage

    Hey. Have this board with liquid damge missing PP3V42. Obvious damage was under the heatsink bar leading to the fins which I replaced as well as U5010. I now have PP3V42 with a green light but only for a minute with 1 fan spin. In diode mode I get 0.088 but this seems to be getting pulled to...

    820-3437 PPVRTC_G3H low.

    Injected voltage on pn 1 of C0892 because I lost pad 1 on C1910. The board is liquid damaged and when I removed it the pad came off with the cap. I went up to 3.3 and no higher. The only thing very slightly warm was the CPU area. I also noticed that pn 2 on U1900 (PP3V3S5) is beeping to ground...

    820-2850 No Audio device detected

    So I replaced U6201 and audio did start to work. After I shut it down and restarted it the audio did not work at all. I'm guessing that t isn't the chip itself but like you said a component around it because it seems like by heating up the area when I replaced the chip is what made it start...

    820-2850 No Audio device detected

    Hi... All recommended components to check are good. I did have to replace DZ6700 and DZ6704 because the where both cracked but these are for audio jack. Other then that everything looks OK. Thanks.

    820-2850 No Audio device detected

    Had checked briefly what was obvious to me on U6201 before I posted. And saw someone suggest U6630 from a Google search. So I guess I was fishing. This is the same board that I just had the BL issue with U9600. Will check your suggestions. Thanks for the help guys.

    820-2850. Video problem after short on PPBus

    LOL. Your probably right. But if you could tell me why the amperage had to be jacked up to get a small voltage output it would be helpful. Is the power supply bad. Because I tried it on a dead board that I dont care about and same shit happened. Also, I meant is it possible to do this repair...

    [SOLVED]820-2850 no backlight

    Tapping U9600 definitely effects it backlight. But doesn't seem to anymore then flexing the rest of that side of the CPU. Maybe that's the week point and anywhere I put pressure on that side of CPU directly effects u9600? Thanks.

    820-2850. Video problem after short on PPBus

    LOL. I plead guilty to the 1st offense. I had bought the Wanptek KPS305D a while back, but never had to use it. Only tested with multi-meter. When I attempted to actually use it for a repair to find the short on PPBUS I had ground attached to a screw hole and voltage on pin 2 on F7040. I was not...
