Repairing my VCS, help needed.

[Keatah]

Read through the thread.

 

Since this console was under muddy water and all that the first thing I'd do correctly and thoroughly clean the board. Remove the chips, wash everything with soap and water to dissolve and remove contaminants. Rinse with deionized or purified water and blow-dry with air compressor. Replace old and affected caps. Use Deoxit on all contacts and IC sockets, switches and cartridge connection pins/slot. Perhaps replace IC sockets. Clean and buff each pin on each IC. And all the other trappings of restoring a board like this.

 

There's simply too much residue causing short circuits and partial short circuits.
