I bought an intellivision motherboard from this guy on ebay and the system worked fine for a while. I let it sit in my closet for a couple months, and now it doesn't work properly. I believe the it powers on just fine because I've checked the readouts from the ribbon and they seemed fine. Alas, no picture is my woe and i was wondering if anyone here had any suggestions. When i turn the system on the screen does nothing. I just get the blank blue screen that says no signal on my tv.

I assume it's an original Intellivision, not an Intellivision II?


It sounds like the TV isn't getting an RF signal. Check the channel switch on the bottom of the console, and double check you're using the correct RF lead and that the TV is tuned properly.


Check the blue wire +12V power connector (the two pins at the back), as well as power at the board end of the ribbon cable.

Check the internal connection from the RCA jack to the rest of the Inty's RF modulator. Those are notorious for breaking free from twisting the RCA cable when plugging/unplugging it.
