Waves moving across screen. Sony WEGA HDTV + Sony PS3

I recently inherited a Sony WEGA Trinitron (KD-36XS955) from a friend who wanted to ditch it for a flat-panel. It's basically a 1080i CRT. The sound, size, and high def quality are amazing; however, I also seem to have inherited a problem he claims he never experienced.

When I watch anything through an HDMI cable with the PS3's display settings at 1080i, there is a soft gray/purple wave continuously moving from right to left. Once every 2 seconds or so does this occur. When I switched it to A/V cables the wave vanished. It doesn't appear on other channels or devices. So I have narrowed it down to the PS3 via HDMI cable. On 720p it's a lot less noticeable, and on 420p it is hardly noticeable at all. All in all, it's more visible on dark images or load screens and is nearly undetectable on bright, moving images. It's quite annoying during dark movies when there are scenes involving little movement.

Searching the net and asking around, the most common reasons I am told are:
1. Not enough power going to the TV.
2. Power supply inside TV is going bad.
3. HDMI port on PS3 or TV is crap.
4. HDMI cable is crap.


Well...
1. I tried every outlet in the room the TV is in. No difference. Also, why does it only do it on HDMI-fed images and not A/V or other channels?
2. Same as #1.
3. HDMI port on PS3 is likely good, and I've used it on other TVs with no issues. The TV is kinda old, but the HDMI port was hardly ever used by my friend. So it's not worn out.
4. After reading a lot of articles, like the popular "Is there any difference between a cheap (i.e. $10 HDMI cable) and an expensive (i.e. $150 HDMI cable)?" post on Playstation[dot]com, I'm poised to believe my cable probably isn't it. I can borrow one from a friend and try.

I have to admit. I'm stumped.

Use red/green/blue component cables as the pic should be equal, they carry a 1080i signal and that's as high as your tv goes anyway, and they will carry an HD signal. There is no need to use HDMI on your tv.

I agree that using component http://img682.imageshack.us/img682/8558/componentcables.jpg may well resolve your issues...

If there is no possible solution with the HDMI, I'll def consider getting those component cables. I guess I just don't want my HDMI cable to go to waste. I didn't get a super expensive one, but it wasn't exactly super duper cheap either ($30, I got it the day I got the TV and it was the cheapest one the store I was at had).

So long as the video quality is genuinely no worse.

Your KD-36XS955 is a 2004 model and, as such, was among the first wave of TVs with HDMI inputs. Some of these early HDMI ports didn't work very well, so it is possible that the HDMI port on your TV is faulty and has been since day 1. Try using one of the two component-video inputs on the TV instead.

BTW, that TV is one of only six models that were equipped with Sony's "Superfine pitch" FD Trintron 1080i HiScan CRT picture tube.

P.S. The TV is not a rear projection TV. It's a direct view TV.

Fair enough. I have tried the Sony PS3 rgb component cables. There is a slightly noticeable increase in picture noise, picture quality otherwise is just as good. But the wave still appears, albeit less obviously, and there is a fine, static black line at the top of the picture (shows up on everything, wasn't there using HDMI).

If you are still getting the wavy line, it is most likely due to some electrical interference between the tv and the PS3. If you can, try plugging the ps3 into a totally different outlet/circuit than the tv and see if it goes away. The static line may be due to a pic size setting, try adjusting what you have available as pic settings.

I will def try plugging the PS3 into a different outlet, but if that works what would be a permanent solution? Having a hideous extension cord going from the PS3 to elsewhere in the house? Man, that would suck. Also, if that's the case, why does this only show up on images coming from the PS3 via HD? On SD(A/V) it's not there. It's basically a vertical, soft, gray/white/purple hued thick line that flows from left to right over and over. Like a repeating pattern, I guess not really what is visually known as a "wave."

As for the black line, I tried the component cables in every allowable part of the TV, I've messed with all of the PS3's output settings. It looks like it's there to stay. At least it's not there on A/V or hdmi.

Don't suppose this looks like a very specific issue to anyone?

Great illustration! I might also mention, a fine display.

Only the PS3 shows the bar?

Looks like a ground loop issue. Try a three prong to two adapter on the PS3. If no joy, do the same for the display.
If still no joy and you have tried as I've read... then the issue is with the TV.

Just to clarify, 'cause I may have mislead some people, but the TV in that graphic I made was for illustration only. That's not the model of TV I have. I have a Sony WEGA Trinitron (KD-36XS955).

I will try the 3 prong -> 2 prong adapter for the PS3. The tv is a 2 prong plug already.

Did a bit of research myself on this one. You don't perhaps have a wired Ethernet connection to the PS3?

That's been known to clog up the pipes, so to speak.

Nope. Wireless.

p.s. The 3-to-2 prong adapters didn't help.

I would like to thank everyone who gave their input and tried to help. I've tried a lot of stuff, assuming it's an electrical/power issue, and I have never been able to fix it. Maybe the power supply box inside the unit is aged and going bad. It's subtle enough that it's not hurting my gaming/movie experiences, so I guess I'll learn to live with it. I don't want to keep bumping this thread forever. If anyone has any new ideas please PM me. I'll check back once a week or so.

Again...thanks.
