Everett1954 Posted July 11, 2017 Share Posted July 11, 2017 So, I have a Sears Video arcade II that originally had no video and audio. I replaced both the TIA and RIOT and got sound and video back. However, the video is out of sync and rolling. The +5VDC is 4.97VDC and there are no shorts or opens on the circuit board. I have tried a dozen known working cartridges and they all do the same thing. Wiggling the cart does nothing. Yes I have cleaned the cartridge slot with contact cleaner. Any ideas? bad cap somewhere or?? Quote Link to comment Share on other sites More sharing options...
Osgeld Posted July 11, 2017 Share Posted July 11, 2017 (edited) have you tried it on another TV? or a TV that supports PAL (a lot of flatscreens nowdays will support ntsc or pal as they are not clock locked to the wall, unlike most CRT monitors) just to rule out the basics Edited July 11, 2017 by Osgeld 1 Quote Link to comment Share on other sites More sharing options...
RamrodHare Posted July 11, 2017 Share Posted July 11, 2017 have you tried it on another TV? or a TV that supports PAL ... I agree with that. If it's rolling, that's the first thing I would check. Quote Link to comment Share on other sites More sharing options...
Everett1954 Posted July 11, 2017 Author Share Posted July 11, 2017 Yep, tried it on a Sony CRT and a Westinghouse LCD flat screen, only differences is on the the flat screen it does not roll. Still torn and distorted. Quote Link to comment Share on other sites More sharing options...
