I bought a 5 pin DIN to 4 RCA jack cable on eBay for my Atari 800 (not an XL). With my Atari, if I hook the composite from this cable to a late 1990's vintage TV/VCR combo TV, I get a decent color picture (blue Atari Memo pad background). Recently I bought a Commodore 1702 monitor as I wanted to try and improve the picture for my Atari 800 by using the 1702's Chroma and Luma input jacks. Problem is I get a black and white picture on the 1702 when doing this with my Atari 800 using my cable. I then tried using the composite with the 1702 (the one that works fine with the old TV/VCR) and I still get a black and white picture! Thinking I might have a problem with my 1702, I hooked a modern DVD player to the 1702's composite input and I get a beautiful color picture.
A while back I had done the same with a modern Samsung big screen TV hooked to my Atari, and I was also get black and white video when using the composite or even the switch box, but when the 1990's TV/VCR combo TV displayed color with the Atari 800 I chalked the problem up to the new Samsung widescreen being ultra picky about its NTSC signal. Now that I see the Commodore monitor doing the same thing with my Atari, I am wondering if the problem is with the Atari?
Has anyone used an Atari 800 and a 1702? Could something be wrong with the video circuitry on my 800? Any pointers are really appreciated!
