A500: Green Screen/11 blinks, reseating chips didn't help...

It also might be that: if there is no expansion card, that may have been installed as chip RAM (just a couple for pads to cut/solder) and now without the card, it's missing half of the chip RAM. If that's what happened, all you will need to do is pop in the RAM expansion card.
The green screen usually means chip RAM, not just RAM.
I hope this helps....

I don't have an A500 here to jog my memory, but there are three solder pads just inboard (to the left, look from the front) that need to be joined/cut in a different configuration to use the 512Kb card as chip RAM.
I'll try to find a photo of a 6a mobo to show you which pads...

No photos, BUT this covers what I am talking about. It lists the pads involved.

See if this helps

Is that a pretty  common cause of this issue?  I want to avoid the shotgun approach if I  can help it.  Then again, recapping is real cheap.

No, bad caps rarely if ever cause this specific problem. It's some where in the chip RAM or custom chips or the pads I mentioned being re-configured.

I can't believe I can't find any pics on the internet!! Here is a video that shows you the exact pads I was talking about. Maybe you can tell if yours have been fiddled with.

 I sure hope something in the mess helps.
