I have some picture distortion - pink fuzzy color where white should be (like on hockey ice). I'm trying to determine if the t-con board is to blame and if I might fix it easily


Hi Bill.

I don't see a specific model for your TV, but have owned a rear projector system before. There is usually a sub-menu where you can do fine alignment of the Red, Green, and Blue projectors to get rid of the pink fringe. There is generally a white crosshair at center screen where you can fine align the three colors to get rid of the fringing, and sometimes an advanced menu where there are crosses all over the screen that you can individually select and fine tune, (tweaking the different optical distortions of the individual projectors to overlap).

If the fringe is a big swath instead of a fine edge, or if a color is totally gone, then you may be talking power amp issues. For fine fringes, the adjustments usually work fine.

Hoping that helps!

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.

When using cable input video is good but sound has fuzzy static


Your TVs tuner tuned a little off frequency. It could be as simple as having cable box on where you have good picture but fuzzy sound, use the TVs remote to change the channel and then change it back to proper channel. If that doesn't fix you may have wrong tuning type selected in channel set up menu.

Screen is green and pink


This can happen if your component cables are not pushed in all the way. Sometimes they become loose, so just make sure they are pushed in all the way.
