Amiga 500 plus with boot problem

[paul1981]

Hi all,

i need help to boot my amiga. I cleaned all chips and replaced the faulty battery with a CR2032 one ( i found a guide for this).

It boot with showing a white screen, but the game get loaded, with video glitches, only if i insert the floppy before power on the amiga but with video.

Is this something that's happened since you took the machine apart and changed the battery? Or did you take it apart because the fault was already present and you changed the battery whilst you were in there because it had leaked? If the latter, are you sure your motherboard wasn't damaged by the leak like many other A500 Plus'?

If you're not getting an "Insert disk" screen, you definitely have either a ROM problem, or a video problem.  :rofl:  (haha, since you know this already)

I'd revisit that ROM issue, though.  When you turn on the power with no disk inserted you should see an "insert disk" screen.  Clean and reseat the ROM, or swap it with another one if you have a spare?

Wouldn't a faulty rom cause a red screen error code? Or maybe not?

Like someone mentioned earlier, could be faulty ram. I think a memory tester from aminet might be an idea? You never know your (dis)luck. lol
