What does this fuzzy image look like? Does it have ghosting shadows. Of course it is possible to align red manually from the convergence menu. But first lets confirm that it is indeed a convergence related problem.

Green line on left side of an image and a red line on right. Such as around a face. Colors just don't line up and picture is very fuzzy. Had another old rear projection and it had a way to align it. Can...


Your other model was more than likely a CRT projector where you coulod manually align the Red/Green/Blue guns. The one you have now is more than likely an LCD projector which can't be readily aligned. Sounds like the panel is failing.

Tv out of foucs


These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

My Tv has red light (color) out of focus..I've tried tuning the lance but it's not the problem in the lance..it's something else..don't know what..do you?


Your TV has three picture tubes which are aligned to properly converge the projected light beams on the screen. Each picture tube projects a single color of Blue Green or Red. During production your TV was carefully adjusted to properly align these colors. As a feature you have the ability to adjust these colors.thats called convergence.If you don't have a manual to show you how to adjust you can find one here http://www.mitsubishi-tv.com/support.html

The picture went fuzzy (color alignment).


craighirman,

try going to the antenna input from the menu screen, then trying to do the auto focus, or manual focus. My Samsung won't let me do the auto focus unless I'm looking at the antenna for some strang reason.

Samsung rear projection tv has multiple images with differnet colors


The auto self focus screws up if the picture does not remain constant or close to it while focusing. It is designed to self focus every fifteen minutes. Go to menu and then setup and turn the auto focus feature off. I have had mine off for the past year and have had no problems. If you slide the bottom portion of the remote down you will see a self focus button. My suggestion is to put a DVD in and hit the pause button during a scene and then hit the self focus button. It should align back up and may take a couple of tries. (If you have an aftermarket remote, just enter the menu and then setup and you can activate the self focus feature, just don't turn it to auto focus!)
