[SOLVED] 820-3332 no picture

[Gannons3]

I have an 820-3332 that sometimes has no picture. when theres no picture I have a 27ohm short to ground on ppvcore_gpu, what are the odds its something on that line other than the gpu being dead? this computer has never had liquid damage either.

Touched up soldering joints on U8900? I’d bet that’s the problem and 27 ohms is not a short btw.

go to any ohms law calculator, type in 1 volt, then 27 ohms. what power output in wattage does it give you?

how many watts do you expect a modern powerful GPU to take?

now tell me why it isn't a short.

follow the instructions here to solve the problem https://www.youtube.com/watch?v=lumJ0cN5oyY

wow that was pretty sad, i didnt even realize that this was the board louis talked about in his video until after you said that. The joints on that chip looked terrible; I touched them up and it appears to be working fine. thanks for the help
