Distorted Picture. All wide angle Cathode Ray Tubes have to have magnets around their periphery at the back. They are fixed on metal strips so they can be moved slightly. The effect is to alter the shape of the picture towards the corners. Try this, but remember their original position in case it gives the wrong change in shape (linearity). There are also parts of the circuit which control linearity by altering the shape of the line or frame scan waveform. In your case it is the line scan which needs correction and there should be several adjustable components. In some TVs, the effect the edjustment has is clearly marked by a symbol or word. You may need special tools and be aware of high voltage parts. Unplug the TV while you move a magnet etc.

I am having trouble getting the screen size back to full size. We used the zoom but that makes the picture to big. My TV is a Auria EQ5588

Hi, The " Size " of a flat panel tv ( when not in zoom mode ) is actually controlled by your programming, if using an hdmi cable from an Hd/Blu-ray player-then whatever format the disc was recorded in is what you'll see ( widescreen/letterbox ) black bars at top & bottom of scrteen ) or full screen. Local over the air digital H.D. brodcast's from networks varie from full screen to letterbox-satellite and cable that are standard definition will almost always letterbox a screen for you. Using T.V.s tuner may alleviate most of the issues. Good luck and I hope this helped. Prodzilla

Background "halo light effect" when using XR-10-XL in 16x9 mode

Do you mean there is a dark grey outline when using it in 16x9 mode? This happens with my projector too. Try using dark (or black) masking around the screen.

Dvd's aren't fitting my screen, the sides and top/bottom is being cut of. I've tried the display menu, zoom, and making it widescreen, and it doesn't work.

Are you playing wide-screen movies on a 4x3=1.33:1 (standard=SD) TV? DVD output by default is SD. Even 16x9=1.78:1 (HD) movies with have top and bottom bars. Many "wide-screen" DVDs are squeezed horizontally so that you have to stretch them. Many theatrical releases are up to 2.7:1 or so. Side bars indicate you have the DVD output set for 4x3 and your TV is HD-like. There are usually controls for the screen format on HD TVs--no controls on SD TV. Hey, early movies were 1:1--take them side bars. More on aspect ratio (AR) in Wiki, I bet. With letterbox of SD you can get "pillar box" with black on all 4 side. Get a better source and/or choose a different AR. -Ken

Rca scenium 52" has light bar area down each side

I take it that you have watched many hours of 4x3 video on this 16x9 TV . What you see is evidence of screen burn, like they used to warn about with the old "pong" type games with stationary objects. The 4x3 pattern is burned into the phosphor in the projection tubes. the area of the burned pattern is not as efficient as the unused areas that make up the 16x9. If you watch enough 16x9 it may even out somewhat, but will never be perfect. Replacing the tubes will fix it, but they're pricey, and you may be subject to it happening again, depending on your viewing habits.

some films were filmed at an aspect ratio greater than that of your TV so you will see black bars on top and bottom of the screen. These are normal. 1.78 is 16:9 so it will fill up the screen but most hollywood blockbusters are filmed at 2.35 so they have scope aspect. TV shows on bluray will for the most part have your 16:9 ratio. Everything's fine so don't worry.

Display size problem

Sound very much like you are in 16X9 mode with a 3X4 signal. That is not uncommon. Do you lose any information, top or bottom with a HD signal? Bink.

Black bars in the picture

For Models: CC4352, CC4362, CC4393. Your camcorder has a wide format recording mode that lets you make recordings compatible with the 16x9 format. When 16x9 is activated, the camcorder records black bars at the top and bottom of the picture to produce the wide-screen (movie) effect. This is also known as "letterbox" recording. Do not use this mode unless you have a compatible 16x9 TV. When played on a regular TV, black bars appear on the screen. If the 16x9 feature is activated on your camcorder and you want to turn it off, press REC/PAUSE to pause recording, and repeatedly press DIGITAL EFFECTS until no digital effects display appears.
