I have an 820-2936 with Intermittant Fan Spin (no Liquid Damage)

PP3V42 - 3.47V
PPBUS_G3H -12.58 V
PP5V_S5 - 5.0 V
PP3V3_S5 - 3.3V
PP5V_S3 - 5V then off, 5V then off
PP3V3_S3 - 3.3V then off, 3.3V then off

I tried new clock chip, same result. Any ideas?

Thanks

No liquid damage.

No CPU VCore

PP5V_S0 and PP1V05_SO are at 5V and 1.05V respectively, but also intermittant (about 250ms on and 3 sec off)

So no voltage pulses at L7510? Check R7402 for corrosion. I doubt this "just" happened, what is the history?
