Blue and red color are off, picture is not clear

Purchase the convergence repair kit......not very hard to do yourself

The tv have a problems known as a convergence problems,it dead.Tv have colors lines R,G,B mis alignments,have colors shadows pictures or 3D pictures look alike?The tv convergene board have dead 2 STK convergence ICS and some or all of it resistors are dead too.These parts on the tv convergence board,must be replaced to solved the tv convergence picture problems.The shop,will cost u like $300-350 for parts and labors.

Sounds like the convergence is out of adjustment....moving the set can cause this as well as components chaging value with age....The kp43ht20 is an older set and may not have the alignment setup in the menu as with the newer sets...but you can go thru the menu to find out...if there is one, then you can try to align the convergence...usually there will be a crosshatch on the tv...when aligning convergence there will be a blue setting and a red setting...you want to select red first and try to get the lines lined up as close together as possible on the red adjustment..then you go to the blue adjustment and do the same...the outcome should be as close as possible to white when everything is lined up properly

Behind the front cover you will see a little plastic box with six phillips headed dials. They only move 180 degrees. The three on the bottom control color richness and the three above them control focus. Turn all three of the bottom ones to the left while the TV is on, then gradually turn them to the right until you get the color you want. NOTE if any one of the three bottom dials are too far up the TV will shut down and will continue to turn off after about 10 seconds after start up until the offending dial is turned back a little.
