I had the Channel F 2 years ago, it didn't have a regular RF modulator but had this UHF type prong deal off one end, wire to the system on the other, and a TV <-> GAME slider on the thing. Is that what you're using and you have more than one or something else? It seems to me if the system itself was dying it wouldn't kind of choose when to work, and not also be chill about the on system reset leaving it working just fine either.

So after pulling and reseating the three main ICs there was no difference in how the console was reacting when turned on. However, after adjusting the Rf Modulator adjustment "screw" I appear to have a consistent picture. The inital picture seems to have very slight garbling, but when it is reset it always resets to a clear white screen withe the G? prompt. Crossing my fingers that this is an easy fix. Wish I had better electronic skills and those that do are probably cringing at my descriptions, but maybe this will get this old machine up and running again.

The G prompt for some reason I think from rotten fuzzy memory is a normal operation of it. I think it means it's looking for a game (G?) when that is there.
Yes, that is exactly what I wanted to see on the screen. Issue appears to be resolved. Fires up every time now. Thanks for all your help folks.

What was the issue? RF modulator out of tune?
Yes, you nailed it! Thanks a million. Now I have a Slot Machine cart that is not behaving. It won't consistently seat/lock when inserted into the console. I don't see any obvious differences in the case compared to the other carts. When it does seat it wants to work but won't. Screen freezes eventually. I am going to pull the pcb and resolder the chip. This console is determined the teach me a thing or two!

I've got a cart 10 that doesn't seat either, but works fine if I can get it to stay put. I've love to know if/how you solve that one!
