Amiga 500+ repair... battery leakage
« on: May 07, 2016, 07:08:24 PM »
hi,

it's my first a500-repair job, this is how it was when i got the amiga500+ and what I did so far:
just quickly boots over and over again.
battery leakage, some parts do not look too good, some traces on the pcb damaged.
did some soldering adding wires, with some success (yellow screen, green screen, red screen).
did more soldering adding wires, more success :-)
now it sometimes shows the bootscreen (rom2.04 insert disk animation)

but it's very unstable, this is the situation now:
- sometimes the amiga shows the bootscreen, then after some amount of time (varies from seconds to minutes) -> powerLED flicker, reboot, software failure guru screen
- sometimes it doesnt, screen colors go from black to grey -> powerLED flicker, reboot
- sometimes it doesnt, screen colors go from black to grey to light grey -> powerLED flicker, reboot
- sometimes it doesnt, screen colors go from black to grey to light grey to white -> powerLED flicker, reboot
(the latter three may rarely show a software failure guru screen, too)

I have to add that U12 got fried pretty good by my soldering "skills", just in case that might be relevant. :)

does that sound familiar to anyone?
any suggestions what to look for or to check next?

thanks!
regards,
ro
