Question about Samsung PCN5425R 54" Rear Projection Television

1 Answer

Lost picture all color lines are at top of screen

Was watching movie, all of a sudden movie appeared to be in 3D. We discontinued watching movie and turned off set. Later, we tried turning set back on and found we had no picture at all just three color lines at top of screen.
Tried to run auto convergence, but menu won't let me get to this option, even after having set unplugged for several days. Believe convergence board may have gone bad.

Thats what happened your convergence went out, those parts can be found online for as little as 12.50 a piece. If you are good with solder its an easy fix. I found a guy on craigslist in denver who fixed it for 150
good luck

Hooked up PS3 to system and when watching DVD's the right side of the picture is blurry and appears doubled, like an old 3D movie without the red and blue glasses. When watching TV everything looks fine.


All projection TV sets have two very common problems. One is convergence ( 3D/Warped video or dead set) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. In some cases the TV will also not show any video. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....


  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Alot of rear projection t.v.'s have a convergence option in the menu on the t.v. There you can set the try to set the colors back how their supposed to. Mine has a cross in the middle of the screen and you just have to try to get all 3 colors to line up. Unfortunately, the actual lens inside mine has to be aligned so it doesnt work. Just something to try though, hope it helps.

GE Rear Projection TV set with "3D" colors


This is a common problem that was NOT caused by watching the 3D movie! Bad solder connections on the high voltage transformer have caused a solder in fuse to blow. The transformer will have to be resoldered and the fuse replaced.

Poss. convergence problem with Hitachi 53UDX10B Ultravision


You have convergence problem. Either bad connections on ics, ics are bad or voltages to convergence circuit are missing. There are no bulbs in this set. 3 picture tubes,red,green and blue produce a picture than when alighned(converged) correctly on top of each other gives you a color picture.When not you get the effect you are describing. Frst you can try the magic focus in the menu.
