820-00840 PPBUS_G3H Short.

[tlough75]

I have on the bench a liquid damaged 820-00840 that had cola spilled on it. the 2 areas that were hit were U7650 and U7220. both PPBUS_G3H and PPBUS_G3H_CPU are 0.8 ohms to ground. Should I even bother injecting 1V, or should I kiss this one goodnight? I did replace U7650, C7651, R7865, C7689, C7680 & C7241.

Again injecting into PPBUS_G3H, whitout checking for short on CPU power supplies chips?

Did you read my post? I didn’t say anything about the fact that I injected voltage. I measured for shorts...using resistance mode with the power off.

I didn't afirm that.
Just saying why do you even THINK about voltage injection???
