Hi all, new to this forum and first attempt at repairing an Amiga. I actually have two, an A500 and A500 Plus. The Plus has some signs of life so I'm going to concentrate on this one first.
The machines were stored many years ago after the kids moved on to Windows based PC's around 1995. They were rediscovered in the loft (attic in the U.S.?) while bringing down the Xmas decorations and my daughter thought it might be a good idea to introduce my 4 year old grandson to the Amiga.
The Plus was working when put away but at that time I was unaware of the damage the Ni-Cad battery could cause and indeed the corrosion looks pretty bad. It has been removed, the PCB cleaned with copious amounts of Isopropyl alcohol and there is some swelling under where it was positioned but the traces on the top layer seem intact, leakage goes right around the edge of the PCB all the way up to the video stage but it does boot and the FDD is clicking but does not seem to detect a disc is inserted. There is monochrome video at the RCA connector but the amplitude seems pretty low, the TV it's connected to often doesn't recognise that sync is present and doesn't unmute the blue screen. It's even worse with the A501 modulator but there is colour, unable to tell if the audio department is OK.
Any tips would be welcome.
