Lost picture all color lines are at top of screen

The tv have a problems known as a convergence pictures problems,it is dead.Tv have any colors lines R,G,B mis alignments,have colors shadows pictures or pictures look like 3D?Yes,than the tv convergence board it is dead.The tv convergence board must have it components parts replaced like 2 STK convergence ICS and some or all of it resistors too.To fixed the tv convergence board to solved the tv convergence pictures problems.The tvs shops will cost u like $300-$350 for parts and labors.

All projection TV sets have two very common problems. One is convergence ( 3D/Warped video or dead set) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

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. In some cases the TV will also not show any video. 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 pics of convergence problems.






Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Convergence problem. Replace a fuse by flyback, (small brown/orange one) and resolder flyback.

replace the convergence chips

No,need to diagnose.It a 100% convergence problems.Convergence problems very easy diagnose.The picture look like 3D,colors lines don't lines up.Fuzzy,out of focus.Convergence controls don't work to lines up any colors cross.The tech is cheating u if he said cost $125 to diagnose.If u know how to solders u could fix this convergence problems about $100.U can buy a convergence kit at Websites Tv repair World.com,Tvrepairkits.com.The shop everythings fix parts and labors only $300.

Alot of rear projection t.v.'s have a convergence option in the menu on the t.v. There you can set the try to set the colors back how their supposed to. Mine has a cross in the middle of the screen and you just have to try to get all 3 colors to line up. Unfortunately, the actual lens inside mine has to be aligned so it doesnt work. Just something to try though, hope it helps.

This is a common problem that was NOT caused by watching the 3D movie! Bad solder connections on the high voltage transformer have caused a solder in fuse to blow. The transformer will have to be resoldered and the fuse replaced.

You have convergence problem. Either bad connections on ics, ics are bad or voltages to convergence circuit are missing. There are no bulbs in this set. 3 picture tubes,red,green and blue produce a picture than when alighned(converged) correctly on top of each other gives you a color picture.When not you get the effect you are describing. Frst you can try the magic focus in the menu.

remove front panel and check the 6 control knobs adjust the intensity of each color as well as the focus of the picture with those colors.be sure to mark the knobs so you can return them to there original position if the set shuts off. Good luck

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