    Default Magnvox Odyssey 2 White and Grey Screen Problem

    For some reason the CPU isn't starting or operating correctly. This can be due to a variety of factors, including problems with:

    -Damaged trace / connection to cartridge ROM
    -Defective TTL chip
    -System clock
    -RESET line
    -Bad RAM / CPU

    Thanks for the reply and suggestions. None of the IC's were getting warm or hot. Just the heat sink on the regulator. Not sure about the regulator as couldn't reach down enough. I'll reflow the cartridge port and post results. Again thanks.

    Resoldered the cart connector and no difference. At this point I'm stumped.

    you happen to have a flat bed scanner to scan the bottom side of the PCB?

    kind of an odd but effective way to check traces and solder joints because the scanners see what ever it scans as being HUGE and so its pretty distortion free.
    also you can post the pics and see if any one else sees any thing

    I clean the port and cartridge, but have no success.
