Anyone here know much about CRT tv's and what might cause...

...the picture to be ever so slightly slanted. Its a widescreen HDTV, and as I look at games and whatnot on it that have horizontal lines running across the bottom of the screen, you can see that the line has a slight slant (higher on the right side, lower on teh left) The problem is, this slant is only on the bottom, not the top, so its not a simple issue of just rotating the picture (my tv has that option). Can the CRT be out of calibration or something to that effect? I know fuckall about this stuff, so if you've ever worked as a tv repairman (I know that's a lot of you), any information is appreciated.

Sounds like you have pincushion problems, which is caused by failing caps. But, it might be something as simple as degaussing the tube.
Either way, I ain't fixin' it.

this was the one purhcase in my life i actually bought that extended store warranty for...manufacturer's warranties are often a fucking joke, but I still rarely have electronics that go bad. Looks like that 1 extended warranty might have been purchased for the right product.

Try slapping it with a ham. Or, you may want to plug the component video cables into a fresh mango for about 12 hours.

What did u plug it in with? It might be an underscan issue.

well, it happens with both the hdtv signals from the hdtv box, and with the xbox stuff. Both are connected through component video.

The tv has 2 component inputs.

Whatever it is, but especially if its component/dvi/hdmi, there might be some underscan or overscan. It is most likely the source's fault, not the tv. When I connect my HDTV to my HTPC with DVI I have adjusted it in such a way that it is a tiny bit overscanned on the right when doing 720p. Thats the best it can do. With S-Video it is underscanned everywhere and the frame is a bit crooked, but thats normal. TVs are made with overscan in mind, so that you don't see these flaws.

Try searching the make and model. It may be a common problem.

My old Sony had an adjustment for that. The reason (I read anyway...) was to adjust for local fluctuations in the earth's magnetic field. Or other things that could generate a magnetic field.

Well, I would have just liked to buy your ATI and SoundBlaster though. Now at 81$US and still 9:25Hrs to go...Good luck. You might want to watch it during the last 20 mnts, how sometimes biddings are going crazy in the end.

Check your TV for a buit in adjustment feature that may be accessable through a menu. You might be able to adjust a setting.

The TV could be sitting to close to a magnet or the internal speakers may be affecting the tube.

It could be a bad cable, especially if it only happens when a particular input on the TV is used.

All guesses.....

If it's under warranty, I say take it to get fixed.

if you're talking about moire, its due to the resolution of the tv vs the resolution of the game plus the current onscreen raster

That's very plausible, as a big speaker or an electric cable too close to the TV. May be even your Christmas tree. Also, try plugging your TV in another outlet.

Its got a rotation adjustment, but this isn't a rotation issue, because its only slanting on the bottom.

reset the display posistioning, and start from scratch. this has happened to me a few times.

there is no 'reset' that i can find. I put the rotation and whatnot back to stanard....but still the slant. Another thing that is a bit fucked is the right side of the screen - there is about a 0.5 cm gap between the edge of the picture and the edge of the viewing screen...sort of like the picture doesn't fill the entire screen as it should. Its not like this on the left side. And sometimes animations on the screen cause that right side to warp in a bit on the top right area...nothing terribly distracting, but definitely noticeable. I'm probably just going to drop it off and have it fixed.
