52 inch rca hdtv has red blue green lines through the top of it the picture is curved and its 3d looking

Looks like the focusing lens may have moved a bit or the projector lamp has gone weak. Get a technician to check up the projector.

There's very little you can do here.

hows the picture? is it 3d looking? do you have the convergence option in the setup menu

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 photos of convergence problems.






Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

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

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

You have a problem with convergence and all you may need to do is replace a fuse. Look up convergence for your tv model and hopefully you will get an answer as to where the fuse is located and how to replace it. Very common for RCA tv's

Hello

red, green, and blue lines curve across the top of tv is cause by defective convergence STK IC or you have open resistor at convergence section. if you have defective RGB Color vertical ramp probably you have defective STK IC..

Thanks...

the ITC222A convergence option missing repair kit at the following link should repair that issue. The kit contains the parts and the instructions on CD
http://www.tvrepairworld.com/

there are 3 brown fuses by the flyback the 1 in the middle is bad

its in your LCD connector re-connect it properly.

it sounds like your convergence is off.

you have Red, Greed & Blue projection guns
through your menu's you will find adjustments for them ...

set your green first then align then red and then blue to the green..

when making this adjustment the tv should put up a caliration signal called a crosshatch
a matrix of H and V lines to align

Replace 2 convergence chips, will start with stk ###-###
