Hello,
Managed to pick up an old Commodore LED watch, the one with the black strap and silver circular bezel on it. I expected it to be completely dead, but, after putting a new set of batteries in and fixing the battery tab, I see it light up the left most digit with "0". Now, from the old manual I found, I should be able to push the small button with my pen and start changing the time with the setting button after. However, the watch never seems to respond at all to anything. Just always stays on with the number 0 on the left. I've disassembled the module and can see there is a bit of corrosion on the board, probably from the old batteries but nothing that looks too serious. Now, my question is if anyone can offer some advice on where I should go from here. I've tried cleaning the battery terminal side of the board very gently with some alcohol on the parts that looked corroded to no avail so far. I'm scared to even go near the other side as it has a crazy small chip with bond wires sticking out of it.
Any ideas on what I could try? Or is this more likely new module time? (In such case.. would anyone know where I could find a new one?)
Cheers
