the old green screen A500 thing...

[creous]

Hi there. Have an old A 500 with RAM Extension card and hundreds of games... It waited about 10 years to be unpacked again- unfortunately it doesn't work. Shows a green screen and the red led flashes 10 times, then it reboots. Ok because I think many newbies have this problem, perhaps you might give a short explanation what one could do- didn't find a good one (not even in this forum).
I already opened everything, cleaned the motherboard (it had lots of dust on it) pressed on every chip. Still nothing. Read that reseating agnus might help (http://theweeks.org/toms-stuff/files/TDTTS_reseat_agnus.txt) But I don't have the right tools and I don't want to ruin everything, so I ask first. Hope someone has the time to give some advice...

bye

Have you checked the ram card?? If it had a battery seated, then it might heave leaked onto the card and that can cause some major problems.

I'd definitely try it without the ram card first, and see if that's the culprit.  Otherwise, try the agnus reseating, thar's my best guess.

hi there

I tried reseating and cleaning Agnus and the other chips. the ram card doesn't have a battery on it. Nothing changed- still the "green screen of death". so...
a) throw away
b) any ideas?

greetings from Heidelberg and thanks i.a.

NEVER "throw away"! :pissed:

You could have a busted chip. My C=64 was in storage for a few years and now the VIC chip needs replacing. Strange thing is, I could get an entire C=64 for the same price as any of the chips. Nostalgia says to repair the old one, though. :-)

I agree with weirdamy.
even if you cant fix it, then you can probably get use of the spare parts someday, or sell/give it away to someone who does.

But anyway, one last suggestion.. try removing any hardware not needed for testing it, like extra ram, floppy drive, hard drive, tv modulator and so on... see if that makes any difference at all.

And if you have a different psu, then try that aswell.

And have a look at your Agnus socket - any cracks visible?

Of course I am NOT going to throw away
my old Amiga 500...served me for years
when I was young (you don't throw away
old friends!) Guess I have to buy a new
old one from ebay.
The AgnusSocket doesn't have any visible
cracks. Tried with/without everything,
the PSU is ok.
Anyway, thanks for advice!
