    if yes

    this could be a few different things in the tv. can you test voltages
    for me>? if not a repair on this one will be odd. i think it is the
    video blanking circuit. i would say vertical but this will take the
    sound out in most cases. do the on screen menus leave also or do they
    stay?

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as 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.

Red power light continuously blinking. no picture no sound.


It could be the lamp went out and needs replacement. The Toshiba website states when this happens to unplug the televison for 10 minutes then plug back in. If that does not work then try another power outlet. If that does not work then call for service

RCA projection TV 65inches, turned it on, the channel can not stay the same, it automatically goes down one continuously, 43->42->41->40->......


Check for stuck button on front of set or on remote. Probably ch. down button. Wiggle button free from jammed condition and ch. should stop changing. If that doesn't solve it unplug set from the wall or power strip for 30 seconds and restart in an attempt to reset. Take batteries out of remote to eliminate it as the culprit, also. And you can change the tv input and use audio/video input if the tuner in the set has gone haywire.Good luck, Russmann.

No picture, sound and flashing red power light...


Pull off the back pressboard. At the bottom left hand corner is the power cord that attaches to the power supply board. There is a white plug that attaches directly to the power cord. With the TV power off, pull this white plug up to disconnect. Then push it back in. Then plug your TV back in and press the power button on the front of the TV. I just did this and it is working fine.
