The picture can be seen, but it seems to have a rainbow aura and looks concaved...although the screen is not warped in any way...it was working perfectly last night...turned it on this morning, and we were...


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.

Red, green and blue colours diveded on my TV


ok well "tube" tellys as they are called use an electro magnet to keep the picture stable and colours correct its called gaussing now if you have a speaker or something magnetic nearby it will stuff up the colors but only normally producing colors like purple,green, or white
if you have colors across the screen (that aren't caused by magnetic force) then you need to take it to a repairer or decide wether or not to buy a new one this issue can turn out to be quite hard to fix and can be expensive the different colored electron guns may be burning or burnt out causing pale color or it could be as simple as a power transistor in the H.V supply has shorted out..and causing power issues to the tube.
hope this helps,ben

Rainbow of colors on screen


I just had a rainbow of colors on my tv screen...i thought it was a problem with my TV...however the screen went the "sign off" screen (verticle lines-red/blue/green) Then all of a sudden the picture came back and all was back to normal again.

So I say it's nto your TV it is a station problem!

The screen has a rainbow of red blue and green on bottom


The specs say this is a CRT type projection system, so it could be related to the display or to the TV. Since this has an SD card, it might be good to plug in the memory card with some pictures on it, and see if the problem persists with a source other than the tuner. That might at least narrow down whether you have a display failure/adjustment issue or something else.

Video distortion


You need to take your tv in and have the picture deflector re-aligned.  This doesn't cost much, My dad had to do that to his a few months ago and it cost 30 bucks.

Rainbow on the tv


The only time I have seen that symptom is when the shadow mask of the picture tube gets loose,What that means is you might be looking at a bad crt,color splashes could be a purity problem but rainbow lines are not.Sometimes that happens by itself or by being drop.Good luck

Has anyone had problems with connecting an 'HDMI to HDMI + SPDIF + RCA L / R Audio Extractor Converter (HDMI input,HDMI+ Audio output)' to a Panasonic PT-53TW53? I have a TiVo Premiere hooked up to my Panasonic PT-53TW53. I use the HDMI out, and RCA R+L outputs on the TiVo, and hook up to the digital in connections on the TV. The conversion of the HDMI out is via an HDMI to DVI cable. This has worked perfectly for years, but recently I wanted to disconnect the TiVo and replace with my Roku or Amazon Fire TV. Both have a single HDMI output. So I purchased an AGPtek HDMI to HDMI + SPDIF + RCA L / R Audio Extractor Converter (HDMI input, HDMI+ Audio output) box, hooking up the HDMI output from the Roku or Fire TV to the input on the extractor/converter, and simply disconnecting the HDMI to DVI and RCA R+L outputs from the TiVo, and plugging them into the outputs on the converter/extractor. The converter/extractor has a 3 position switch: PASS, 2CH audio, or 5.1CH (via and SPDIF or Toslink cable). I have had 2 of these converter/extractors, and with both the Roku and Fire TV I got the same results with both converter/extractors: With the switch on 2CH, which is where I understand I should get HDMI video and 2CH RCA audio, all I get is the RCA audio. No video. If I switch to PASS I get video with no audio. Of course on the 5.1 setting I get nothing, since the TV does not support SPDIF. Yet I see reviews all over Amazon indicating folks are using this converter/extractor for this very purpose, and it is working fine. I can't possibly imagine that it is some sort of incompatibility issue with the TV, since the TiVo has worked (and continues to) fine for years. Any ideas?
