Question about Projection Televisions

1 Answer

White horizontal lines on screen

I have a Samsung rear projection tv model pch521r serial number 39zk600104r. The picture has white horizontal lines across the screen. The picture seems ok but when the credits roll up the screen they seem bend as if they were rolling up a peice of clean tin. You do not see the lines when you have a white/snow picture. It's only in the video mode no matter if you are watching satelite, regular tv or a dvd. What do you think.

It needs to be repaired by having the convergence ICs replaced or resoldered (if intermittent).

Parts are STK 392-570. Be sure to use thermal paste on the ICs.

Red and blue ghosting,

The most likely cause is shorted convergence chips and possibly a few pico fuses.

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. 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,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

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

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

1) Loss of color = bad solder connects on signal board

2) Loss of pix = probable CRT coolant leak onto signal board
Have a technician check it out.....can be expensive......T.
