Picture Problems: Snow, color, lines

The tv problems is call a convergence picture problems,it is just starting to developing.This problems when it is fully developing into a convergence picture problems to the tv eventually.Tv will develope into a colors lines R,G,B mis alignments,have a colors shadow pictures or into a picture 3D look alike.Eventually the tv convergence board will dies,have to have it parts replaced like 2 STK convergence ICS and some or all of it resistors too.This problems the tvs shops will cost u like $300-350 for parts and lobors.

The bulb is not the problem.Unplug,replug the tv about an hour.Reset the colors setting back to factory setting.The tv work,should be back to normal.Not than ur Signal tuner board have problems must replaced.

You need to turn the voltage on the red tube down slightly, also you would need to adjust focus to compensate for the lower voltage to the red tube. On the left and right bottom side of speaker cover are two round covers, take them out and there are 2 1/4" hex screws take them out carefully take cover off, there is another service cover same hex screws remove. You will see the focus block on the right side, tubes are labled on block. 2 knobs for each tube. Make voltage adjustments while tv is on a black screen, then for focus, turn color all the way off in the menu, and adjust focus until it looks right in black and white. These adjustments should only be very small; if alot of adjustment is needed, you may have other issues.

Projection sets have two very common problems outlined below.

The first common problem is convergence

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. The TV can also shut down when the convergence starts to fail.

Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith, RCA and others.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
