Dead SNES - SNS-001 (SHVC-CPU-01) - Power, but no blank picture / no sound

[kschafer2598]

Hey all,

I have a SNS-001 from a buddy of mine that won't turn on. It's the older model w/ the SHVC daughter board.

It powers on, but does not display any video. Depending on the game, after a few seconds of power you will hear a random blip of sound appropriate for that game. For Mario World, you might get a bit of a yoshi sound.

Games being tested work fine on other systems.

Otherwise, nothing - screen goes black and nothing further.

So far:

I've cleaned and reflowed and problem areas.
Cap-kit installed - all electrolytic caps on board and daughterboard replaced.

Next:

I'm thinking about reflowing the CPU / PPU chips.

Any thoughts?
