Please do us a favor and rate this solution after reading.

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from www.TvRepairKits.com

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. 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.

are you sure it need to be replaced or did you try to clean it first?

RCA P56950 56"... | Answered on Feb 20, 2011


blowing the fuse means that you have a shorted parts on your unit, it is mainly due to a shorted rectifier diode/voltage regulator i.c.,check it and replace the shorted parts will cure the problem also replace the open fusible resistor.

Use a different input and choose that input on the TV.

YOU HAVE BAD BUTTONS ON THE FRONT PANEL THEY ARE STICKING OR ARE SHORTED.

RCA P56950 56"... | Answered on Sep 14, 2009


It sounds as if you have a convergence issue. If you go into the menue with the remote control
and highlite the screen selection. this should get you to the convergence selection. if you highlite
the RED selection and use the arrow buttons on the remote, you should be able to move the RED
either vertically or horizonally over top of the green line. Do the same with the BLUE selection.
If they do not move, you probly have a failure with the Convergence power Supply. To my knowlege, that board is no longer available and you would need a professioal Service tech to repair the board.
Hope this helps,

Bad FBT flyback transfomer,ck hori output transistor.

RCA P56950 56"... | Answered on Jun 11, 2009


you probably have a little of both. the shutting off is definately heat related but could be too much dust on heatsinks, etc causing it to shutdown. cleaning may eliminate problem but could be a sign of an underlying issue..
the dust can really cause the picture to dim. most of these tvs you can pull the "lightbox" or guts out of the cabinet to clean all 3 lenses, and clean the mirror if needed. don't mess with the screens except cleaning the front from outside. usually a 1/4" driver will be all you need, and a soft cloth for the lenses. use compressed air or a vacuum to clean out dust which will help with cooling, but the picture is only effected by dust on lenses, mirror, and screens.

Horizontal output transistor is needing replacement for sure and quite possibly the flyback as well
