Question about Samsung PCN5425R 54" Rear Projection Television

Convergence problem, blue ghosts

Blue ghost convergence problems
I have a Samsung PCN-5425 Rear Projection TV. The top half of my screen has a blue convergence issue. Yesterday I was able to align it, but now it's off again today. Can't get it to converge now. Red and green are fine. Sounds like I need 2 Convergence IC's?

    I didn't get a response from anyone, so I took an educated guess that it was the IC's. A friend of mine that is an electrical engineer took care of the desoldering/soldering, and I fixed my convergence problem for $52. Would have cost me that much to have someone look at it.

    Problem solved, big screen saved!

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

Color convergence problem


If you follow the instructions on the other thread, you should be able to resolve the problem. Try the simple stuff first. Resolder the pins of the convergence ICs and see if that alone resolves the problem. Sometimes that is all it takes.

Keep us posted.
