Sounds kind of strange to me. I would get on the "Best Electronics" or B&C
Computers" websites and ask them. They do repair on any Atari item.

Problem fixed. It was a short circuit on the motherboard with or
around the colour pot. I resoldered the motherboard connections to the
pot, and spun the pot a few times to clean out any oxidization and the
colour is restored. Seems this type of problem can develop because the
motherboard is gently flexed when cartridges are inserted and removed.
After years of use this flexing can lead to short circuits. >> Stay informed about: Atari 7800 no colour in 2600 mode! Please help... |

Geez. Nice job. I could not have done it.
