I have a Samsung Model PCN5425R Rear Projection TV. When I try to set the convergence, the red will not move whatever I do, but the blue works fine.

If it is rear projection set it uses either two of the STK-392-020 OR STK-392-040 CHIPS FOR CONVERGENCE OUTPUT.

BOTH WILL HAVE TO BE REPLACED; NOTE THAT THESE SETS ALSO HAVE "PICO" FUSES ON THE BOARD FOR EACH CHIP--no movement means one of the fuses is blown because the chip shorted.

This can be a do it yourself repair if you are handy; total parts cost if the parts purchased on Ebay is under 30 dollars.

Let me know if I can assist you and if you have any questions reply to the posting here.

Samsung Tantus (SP-43J8PF) Has Green Tinge - Easy fix?

You may try to get into the service menu and adjust screens/drives level(procedure below). But first turn the color off completely and adjust you brightness to mid-range, what you`ll want to do is a grey raster or bring it as black and white as you can while adjusting the red/green /blue guns or tubes. Also get a piece of paper and pen because you`ll want to record the original values of the items you may change. You want to go into the adjustment menu. Hope this will help Good luck
In quick sequence on the remote press:
MUTE - 1 - 8 - 2 - POWER buttons.

The TV will turn On with the Service Menu displayed.

Select the function and use the VOL+ button to enter.
Save settings and exit by pushing MUTE twice then POWER .

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
