Tried the other input on the TV. No dice. DVD picture works fine but no games. Tried all three inputs on the reciever with the DVD in interlaced and progressive, they all work fine.
The only option left is the cables for the gaming units but they plug in with more of pin attachment rather than RCA (on the console end) and I don't have spares floating around to use. I will have to get some this weekend. And how the cables could work with the TV and not the receiver is beyond me.
I am at my wits end. Logic is telling me it has to be something so insanely simple and over looked but what? I've talked to Yamaha and Panasonic. I have had friends over... Everyone is stumped.

I've followed the thread and have abt 20 yrs experience as elec. tech., but can't visualize anything you haven't already tried. There's virtually no way you could have a cable failure, even with poor quality cables since all you're dealing with is copper wire and a couple of solder or crimp connections. You can always check them with a continuity tester.
I once had an "impossible" problem regarding a tv screen that locked up in an all blue mode. As I narrowed the problem down, it seemed to happen less frequently -- was that just me being more observent or careful? Finally, as I recall, it turned out to be that I had both svid and rf inputs hooked up and there was some residual signal on one of the two inputs which was telling the TV to switch to the Video Input mode, where there happened to be no information. Something like that, anyway. My guess is that something is telling the receiver/processor to not output the comp. vid signals. Got 'scope??
ABOUT CABLES: Outlaw Audio makes some fantastic, reasonably priced cables with RCA plugs which operate much like the chuck on an electric drill. The barrel tightens a split sleeve which absolutly locks them on. A turn or two of the barrell and they practically fall off! Try them.

  The receiver will pass comp signals from the DVD player on all comp inputs and that is what keeps baffling me. I would think if it was stuck some how it wouldn't pass any signal.
  The reason I was wondering about cables is that the monsters go on tight and the space between inputs is even tighter. My hand slipped off of them and jerked the wire that goes into the plug. On a visual observation the cable looks fine when the barrel is unscrewed.
  I have treated the receiver with loving care as it is amazingly musical, the new flagship Denon's/Pioneer/BK's can beat it for home theater, but for 2 chanell music.... I don't know, the Yammy sounds good and the 5803 just didn't impress me (YMMV). And the cables have only been unplugged maybe 4 times total before this mess started.
  I picked up a new cable system for the xbox (since it is high def and the difference is noticeable using just Svid) and still no luck.
  The only cable option I have for the video games is monster cable or stock and as such I went with monster at the time. I do have to say that I have been pretty pleased with the Monster video cables, especially when you get into the Z series.
  So up to now the AA board is baffled. I have had two friends over to help and they were baffled. I've called Yamaha and they were baffled. Called the dealer that sold me the receiver and their tech was baffled. He put me in touch with another tech that told me Yammy has had some problems with their comp video inputs and cards, but how it still works with the DVD didn't make sense to him (or anyone). He did say that he would replace the video board and inputs as that is really all it could be at this point.
  So on Monday I am going to drop off the receiver and have the inputs and board replaced. Just hope it goes quick as I can go with out home theater for a week or two but can't live without music.
  
  Again you guys - thanks for the help.

  There's nothing wrong with the MonsterCables that he's using. The extra grip is a plus, as long as you don't make frequent connects/disconnects.
  You seem to be referencing what's called locking RCA connectors. The problem with these is that most people overtighten the barrels and change the impedance of the overall connection (not good for video, on top of the fact that RCAs aren't 75Ohm to begin with). The MonsterCable products are tight, but not so tight as to present a problem in this area.
