noted battery acid damage, did you first sand back the corrosion before treating it with the water/vinegar? I normally remove all components in the corrosion area, then sand and treat before replacing parts.
No I didn't do this..From looking at where it had gone, it would have been a lot of resistors. I suspect if I had removed them the pads would have gone too.
I will mostly likely get a Rottendog replacement. They're not super expensive but no one has them at the moment..I get the feeling I will be chasing my tail in the long term.
From what u describer, it kinds reaks of a pin being held HI or Low due to a nearby shorting pin/track...
Try metering between adjacent pins on the chip(s) you replaced, and see if there any obvious shorts there.
MM.
You might have to dumb it down a bit for me MM...I've buzzed out the suspect pins with other pins around it if this is what you mean?
