#3717807 Atari 800 display issues

It was the CPU board.  Just got a replacement today and seems to work fine with the video.  

 

So if you get a rolling video screen on both RF and monitor out, and your unit is not PAL on NTSC (or the other way round) and you have tested the voltages, and reseated/ swapped the RAM to test, and tried reseating CPU chips, try replacing the CPU board.

 

Thanks again for all those that helped me get my atari monitor displaying again!!!!

 

One more atari resurrected from the graveyard!

So progress...  I bought an old 20" CRT TV to test (authentic experience lol?) and I basically see a cycling image of the memo pad:

Via Monitor out cable

Via RF

 

Any ideas how to fix?

[sorry I couldn't get the images to work]
