Hello everyone,
I am in some need of direction in regards to my poor old ColecoVision. First off, let me say that I have/had a bad power supply. I found that the +5 was reading 0 when i tested it on a voltmeter. I went ahead and resoldered the connection and now the Coleco powers on. However, there is a nasty hissing sound and the graphics are horrible (rolling, glitches, random resets, etc.). I know, I know...check the power switch! Yes I cleaned that sucker up nice with some dielectric grease and all that and I fit the cap back on nice and snug and it has made no difference. So my question is could the bad sound and graphics still be caused by a faulty power supply? If not, then what else should I look at? Help me Atariage...you're my only hope.
Thanks in advance,
