I just got a Mitsubishi WD57731, and when hooked up to the NES SNES and N64 (through composite), the display vibrates up and down a bit. This is very annoying, and I imagine it has to do with some sort of interlacing or timing with these old systems. I have hooked up a gamecube and VCR through the same composite inputs with no problems.

Has anyone else had this sort of problem with their HDTV? I'm just trying to figure out where to start to solve this. The Mitsubishi menu does not contain very many options, so I've tried most every variable in the menu.

Thanks

Well the first thing i would try at least with the SNES and your N64 is use a s-video cable with them. You'll get alot better picture for starters. The snes 2 version doesn't have it nor do most of the later gen N64's in the colored shells. I would suggest that first but i have no idea on the NES. Sorry.

I gave up a year or so ago and ended up buying and building a RGB to component converter for my old systems. It means all custom cables but the picture is so worth it. Best of luck man!

Have you tried running the systems through the VCR?

Dang I didn't even think of that but that is a great idea. It will stablize most wonky video signals for older systems where the timing is not quite on. I'd say give it a shot. Also try to get everything on the same power outlit and make sure your cables aren't wound around or too near the power supplies. Thats all i can really think of. Let us know what happens!

Thanks for the replies guys.

I wanted to run it through my VCR, but haven't gotten it to work (the input is broken, I'm not pushing the right buttons, or maybe the VCR itself doesn't like the nintendo signal). I will look for another one to try.

I have also ordered an s-video cable for the SNES to see if that helps.

So hopefully next week I will have it fixed and let you guys know.

I really appreciate the responses.

oh, I also tried plugging it into the composite inputs to my cable box. it just displayed a static jumble.

update: the s-video for SNES did not fix this problem.

Sounds like your display doesn't like the 240p signal coming from the game consoles. I had a similar problem and ended up purchasing an XRGB-2 to hook up my old consoles with. The plus side is I've got them running off of RGB connections now, which look much better.

Thanks Karl. I was hoping I wouldn't have to buy an external upconverter, but it sounds like a good idea. Can you tell me where you got yours? I know they're discontinued...

I got mine off of Ebay. I went a little crazy and bought the XRGB-2, 2+, and 3. Ended up keeping the 2 as it had the best picture. The other two had some very slight waves in them, but I am very picky with this stuff...

update: RF modulator/switcher (composite input, coax output) did not fix it
