Used A500 issues

[TheMagicM]

I bought a used Amiga 500, buyer tested it to the best of his abilities (showed kickstart on the screen, drive clicking).

At any rate, my Indivision ECS is in, plugged in my A500 to actually use it but my display is strange and keyboard doesnt work.

For example, I have kickstart 2.04 roms and at the kickstart screen the floppy disk is mangled and the Amiga checkmark is in bad shape.   My caps lock is blinking, pattern is 2 quick blinks.

Any clues as to what could be ailing my new to me A500?

Without the Indivsion board, I still have the same issues.

No mem expainsion.. Rev 5 mobo.  I've pressed down on all the chips.   I have a PLCC extractor so I'll remove agnus and reseat it.  Luckily a local Amiga group has either a replacement A500 for me or chips.  I'm hoping the soldered ram isnt bad.   Also when sitting at the KS screen, keyboard doesnt work, only the caps light is blinking twice.  Maybe the chip ram is bad?

Do you have another power supply at disposal? You see, those voltages must be right. I had one supply which caused blurry image on any Amiga I tried, another bad brick was causing system crashes randomly, so one possibility here.

No.  I'm going to get an ATX PSU, chop off the end of the original A500 that way I can use a new PSU.  

@mechy:

Yea..checked that..plugged in correctly..  kb ram check means, chip ram is bad, correct?
