This is a convergence problem and if you can solder, you should be able to fix this yourself. First open up the back and locate the convergence ICs. These are large black ICs attached to a heatsink and should be marked STKxxx. Post the markings here and I'll confirm you have the correct ones. Try resoldering the pins on the ICs. If that fails to resolve the problem, you will need to replace them.

Keep me posted,
Dan

Double vision lines of red and green


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

My mom has a samsung hc-p4752w and my stepfather heard a pop with a burning smell and after that his tv has a double vision look. so i saw on here how to fix the grid which worked fine except the red...


Convergence IC's are bad......

You can mess around with ordering them, and replacing them, and hunting for the bad resistors on the board and replacing those too, or you can order a new board PN BP94-01266a for around $160, and plug it in. You'll have to readjust the convergence manually afterward. Just did it on my set - works beautifully!

All screen is red


IF THE SCREEN IS ALL RED WITH VIDEO VISIBLE AND RETRACE LINES. ADJUST SCREEN CONTROL IN THE FRONT FOR THE RED TUBE ONLY. TURN CONTROL COUNTER CLOCKWISE. IF THAT DOESNT DO IT THE TUBE CAN BE REJUVINATED.

BLUE DOUBLE VISION


It sounds like you may have a loose solder connection either in the convergence circuit or the pincushion correction circuit. If you can't visually locate it, you may need a service manual and test equipment to track it down. I doubt that changing parts will be the cure if it is an intermittent problem.
