What kind of connections to the tv have you tried? Have you tried using differnt connections from the core to the tv, could just be bad cables. Its happened to me more than once...

That is most definitely not the result of a bad video connection (ports, cables, or otherwise).

This is made evident by the pic of the BIOS screen with the garbage characters. Internal issue, no question.

I opened it up and here is a close up of the RAM chips-

Any ideas where I can score replacements or can I substitute anything else for them?

Hmm... Link?

Here is what I'm looking at as a replacement-

I think either one of these should do the trick-

Hello and thanks for this post.  :mrgreen:

What was the result with the new RAM chips in the Coregrafx? The reason why I ask is because I had a similar video issue with my PC Engine Duo; Good CPU, bad RAM. After reading the thread here, I ended up ordering the same set of SRAM from arcadecomponents.com.

I'll carry my issue over to a new topic and have some photos posted soon.

Cheers, and thanks for helping diagnose my problem.

Cheers, I'm still waiting on the RAM to arrive from arcadecomponents.com. :-k . I had this same problem with a model 2 Genesis some years back and I turned it into a paperweight.
