I recently purchased an Intellivision and I played it fine for a day. Then, I plugged in the Intellivoice module thing, and the picture started glitching up, and the sound stopped working.
I replaced the cable with a different one, took out the module, and now the picture works, but bounces up and down a little bit, and the sound wavers on and off
What can I do??? This is very annoying, and I would like to be able to fix it.
I don't know if it was caused by the Intellivoice module or not, is that a possibility?
