I'm repairing a Dolly Parton, which has stood uncovered in an open shed for the past 16 years.
After some preventive maintenance and fixes I got the game going without any major issues. One of the feature lights wasn't working and the 5101 socket is a bit flaky. I went to troubleshoot the light issue and was in for a nasty corrosion surprise on the back of the lamp driver board.
I took out the battery a while ago and it hadn't leaked if I remember correctly. I'm starting to question that now since there is some corrosion near where the battery once was (see R134, R29, and the capacitor next to R23). But the worst damage seems to be near the mounting brackets and screws on both boards?
I have dealt with alkaline corrosion in the past, but nothing like this. I believe these boards have a NiCad battery on them, is it the same procedure? Did this even get caused by the battery? Hope someone can point me in the right direction on how to proceed with this one.
