That looks pretty messed up, moreso than the usual bad 800XL video. Can you take a pic with BASIC (READY prompt, a few lines of BASIC code, etc).?
Provide a picture or link to the DIN ==> RCA connector. There are several out there and not all of them are the correct orientation.
Example: Red/White do not always mean Audio Out, etc.
I bought a generic one off ebay and it uses Yellow for Video Out and Black for Audio Out. Red/White cables are not used.
I use that one on my TI-99/4A and bought a Best Electronics one for my 8-bits.
Here's several pics, and it looks even worse in person. It was hooked up to first component output (line A), as seen on the back of the PVM. After the pic, I tried it in the second component output (line B), and it looked the same (the "Self Test" was from the second output).
I bought the cable on eBay, and here is the link. What I found strange was that white is the video, and yellow is audio. Possibly cheap cable?
I am lucky enough that I own another PVM, a smaller 13". I could try it out on that, but somehow I feel the results will be the same.
Edit: Well, upon further reading of the description, it says "Note * these cables are made for monochrome monitors. The use of this cable on certain color TV's will result in a black and white picture. Connect pin 4 and 1 together and it will work in color. This will needed to be done internally in your computer."
Looks like I missed an important part. Oh well, I'll order another cable. This one looks good.
