52inch projection screen television has only red and green colors and its difficult to see the picture.


If the picture looks 3d with lines bowed it may be a convergence problem---go into the customer menu and call up convergence and at least look.

Picture looks like 3d i have ajusted screen but keeps going back to 3d and picture is bowed


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

Could use some help with a "bowed" picture on my RCA P52960


Is the convcergence ( Alignment) also off which gives the TV a 3D look around items on the screen? If so replace the STK730-130 on the convergence power supply

Picture is all distorted ,colors dont match up need 3d glasses to watch


HI, this is basic convergence failure. the convergence board controls the RGB stream and , if its malfunctioning or, the convergence chip set is damaged, it will distort the entire display and the colors will not be regulated correctly as you are experiencing at this time.

simply replacing the convergence board in this unit will fix your issue.

Bow tie looking picture with 3d color mis-alignment


you have lost convergence. First thing to check is to see if you are missing the convergence option in the customer setup menu. if you do not have this option then i suggest reading the article in the tips and tricks section entiltled "the fl231 fuse problem" this is a common and sometime easy repair if you do have it then you might need a convergence power board
