Problem with Sears Video Arcade II


Everett1954

Recommended Posts

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??

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
