Double vision with a lot of yellow color

Our televsion has double vision image on all images except in the middle portion of the tv screen. Same is true for the yellow color. It's most apparent from the top and bottom center. Has anyone had a similiar problem or solution to this problem?

This looks like bad convergance. If only one color is affected it may be one of the convergance IC's. It is best to replace both IC's though. If you change the IC's then check the resistors next to the IC's. Use the exact part numbers. STK392-110 IC's can be upgraded to a STK392-180 for better heat strength. (That is why they blow, too much heat generated. Use a liberal amount of Silicone Heat sink compound.) A shorted IC will usually blow a resistor. If a bad resistor that isn't changed it will look like the new chip is bad. Make sure that you use the same wattage and the exact value (Ohms). Your convergance will not be right with an off value resistor. This info works for about any other brand Projo TV. Cheers, Lee http://www.crazycomputers.com

We have a panosonic projection hdtv and the msg on our tv said replace lamp and reset the lamp hour meter well we did that and now its kinda blurry/double vision i called the manufacture and said ill need...

In your tv the image is generated this way: the bulb makes the light; that light is reflected by a panel with a lot of tiny mirrors which generates a black/white image; that image goes thru a set of colored disks on a wheel that rotates which gives the image color; that image goes thru a set of lenses (called the image engine) and it's projected on the screen.
No convergence here - you see the fuzzy image because either the color wheel isn't aligned properly or (more likely) the lenses in the image engine are deformed.
The second one can't be fixed and replacing the lenses will cost more than the tv is worth. You might be able to realign the wheel, but this must be done by someone with a lot of experience and it will be costly.

Double images on screen

IT SOUNDS LIKE A PINCUSHION PROBLEM. IN MOST CASES IT IS DUE TO CAPACITORS GOING BAD ON THE BOARD. OTHER TIMES SOME TV'S HAVE LARGE MICROCHIPS THAT RUN THE PINCUSHION AND COLOR SYNC. HOPE THAT HELPS.

My rca projection tv has blue and green images like a 3D picture would without your 3D glasses, a double vision image and no other colors

sounds like the sensors are out of focus and your red sensor isnt turning on. look in the back of the tv for a master reset button or in your menu screen some sort of "Flash focus" or "convergence". They will realign the 3 sensors.

Samsung HCN4727W Rear Projection TV, green screen, audio works

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,Akai2_bing.gif,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...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*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

Panasonic PT-51HX41 rear projection tv showing shadow/double images.

Unplug the TV from the ac wall outlet for about 4 minutes then plug it back in and turn it on. If it still has a double image then tell me if it's affecting the menu screen from the TV (not the cable menu). And is the double image in red and blue?
