Amiga 500 repair question

[F0LLETT]

It's just a regular A500, Rev 5 motherboard. I don't see any blown caps, but I'm no expert. I tried replacing the Denise chip. It worked normally one time, then went back to displaying the black lines and wouldn't boot. I'm afraid I just blew the replacement chip.

I never see any A500 faulty, only even seen dodgy connections. Try reseating all chips.
I see really wierd stuff, if the CPU connections are poor.

The keyboard membrane traces might be possible to repair with silver glue, but it's difficult. You can use a multimeter to measure the resistance between the membrane pads and the connector to the little circuit board on the keyboard frame.

Your forgetting something. This is an A500. Completely different to A600 / A1200. Keyboard chip is on keyboard. So its more than likely an issue there, as apposed to membrane itself.
