Rainbow on the screen

I have the similar problem, I am seeing like a rainbow on the bottom of my screen, it's mostly showing blue, and a little bit of the blue on top of the screen too, but not nearly as much, and not in the form of the rainbow either, I can also see the words on the bottom of screen are doubled on the rainbow, could this be the same problem with this ICs thing? I appreciate any advise you can give me, thanks. Having the same problem - wavy lines on the bottom with lower left screen showing double words or colors. Any advice?

I have essentially the same issue, which happened suddenly today without any provocation. It's a discolored rainbow on the bottom with lettering being doubled and in a curving alignment. I haven't put anything new around the entire area.

A little more information would be helpful but take a look at some photos and see if they look ANYTHING LIKE your problem,

If they do you have a convergence problem and an exact model number would allow me to assist here more.

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.

Sometimes I get a rainbow on the bottom of the screen.


Your TV most likely has a convergence failure. ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem


  • 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.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Blue line trouble


Hi Kracka,

Are you able to post a picture of the problem?

It sounds from your description that it might be a 'convergence' problem which is when the red, green and blue parts of the image aren't alligned properly.

Check in your menu to see if there is a convergence setting.

Hope this helps

Andy

Seeing the blue green and red lights through the screen


I hate to be the one to say it, but it sounds like the mirror broke in transit. I've had several where this happened without the person handling it noticed, or at least said they didn't. Usually on a 51" magnavox you must first have a star driver or a star bit. For some reason they decided to change from the standard when building these. First, pullthe screen saver and frame towards you with both hands. There are clips that hold it in place and it will pop back in place easily. Then remove all star screws around screen frame and slide out carefully. Screen can slide out of frame so hold on from bottom and top. This will reveal the tubes and mirror. Most screens and mirrors are 100.00-300.00 so use caution not to scratch anything. Good luck, Russmann.

It sounds like you will have to replace the convergence IC's in this TV set. Not a really hard repair to do but you will need to know how to solder and work on solid state printed circuit boards. 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?
