Willsy Posted August 17, 2014 Share Posted August 17, 2014 Velleman make a very small amplifier that fits perfectly inside the console. If you search this forum for velleman you'll probably find the article that I posted. Quote Link to comment Share on other sites More sharing options...
sjt Posted August 17, 2014 Share Posted August 17, 2014 (edited) Most likely it's a bad video ram chip. Get a known "good" chip , bend the pins slightly in and place it over the top of each ram. (all pins must make contact) Note: there could be more than one bad. When you hit the bad one the screen will improve.

dphirschler Posted May 22, 2016 Author Share Posted May 22, 2016 I wound up desoldering them. I'd still like to identify the bad chip so I can throw it out. Darryl Quote Link to comment Share on other sites More sharing options...
