Clean sima-simatic motherboards in dishwasher

[Trinity]

I have a Macintosh Classic with 2 motherboads both affected by the sima-sima syndrome (vertical lines, no startup). I have read in some sites that clean them in the dishwasher can be the solution, can someone confirm me if this is true or not?

Usually, the issue requires replacing the damaged capacitors as well. What dish washing resolves is cleaning the spilled "capacitor goo". If the capacitors are still bad, you won't fix much.

I'd suggest washing, then replacing *ALL* capacitors on the board.
