Seeing double on our Pioneer SD-533HD5

Help, we are seeing double on our TV. The bottom portion of the set now has "dome" shaped purple area that appears to be pushing the colors up causing everything to appear as a carbon copy just above itself. We have tried changing the settings on color, picture, etc., but nothing seems to be helping.

The convergence IC's need to be replaced. look for stk letters and some numbers on them. If You are familiar with electronics repair try replacing them but be careful there is high voltage in the set even after unpluging it from the wall. Post back

How do I repair the color on my Samsung LCD TV. I can still see the picture but 3/4 of the TV goes green/purple/pink and the bottom 1/4 has normal color.

The T con Board or the LCD panel is faulty. Can confirm by replacing the TCON board.

Projection TV sets have two very common problems listed below.

Problem #1) Convergence

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

My T.V. has a funny color .. more of double viewing with purple and green what can I do to fix this?

Your set has a problem with its convergence circuitry. In many cases this can be simply failure of solder connections to the output integrated circuits due to the heat they generate, and resoldering them fixes the trouble. This is a repair you might be able to try for yourself if you have experience with electronic soldering. Or there might be component failure which would require the equipment to isolate and replace the bad parts, which is a repair level best left to professionals. In some cases where the set has digital convergence, the failure might be in the computer control portion. This means the repair might range from only a very few dollars in parts to quite a lot of dollars, plus whatever labor rate the servicer charges. If you aren't looking for an excuse to replace the set, getting an estimate on a professional repair would be the best suggestion.

Degaussing is deliberately applying a magnetic field to the face of a picture tube. This is done to neutralize the effect of other magnetic fields that can cause color distortion. Degaussing isn't done in projection sets because they have separate tubes for each color.

Sony trinitron 32 " purple area on screen

Check any magnatic device near TV which causes purple color on screen. That device can be Speaker, Electronic toy, Watch like that carring piece of magnet inside. Remove that device and turn OFF your TV for half a hour, then power again. Hope the color will be fine n normal on entire screen.

Panasonic Model No. PT-47WX42F

Replace the convergence amps. That unit takes two Sanyo STK392-110 and you could use 150's for greater reliability. Also replace one or more of the 1.2 ohm resistors in the yoke return circuit out front of the amps.
