Daverey1956 Posted August 12, 2016 Share Posted August 12, 2016 I got 2 Colecovisions. bought them cheap on ebay. One worked ok but had bad power supply. The other works fine but no audio, just white noise. Anyway I replaced power switch on working colecovision and it helped clean up the picture. So I think I'll do the same thing on the colecovision that has no sound. maybe that will work. I'd like to have a backup unit. If it is the sound chip, can it be replaced?

Bmack36 Posted August 12, 2016 Share Posted August 12, 2016 You might need to make an adjustment to the audio pot on the RF box. Quote Link to comment Share on other sites More sharing options...
