Most likely a fault in the vertical deflection circuit or sometimes but rare, in the video circuit. Your problem could be a vertical registration problem(convergence), a bad vertical drive or verical output falure, or a fault at the sweep power suply that feeds the voltage to the verticle circuit. In my opinion, this repair, if it is what I think it is, should run anywhere from 200 bucks, all the way up to 450 bucks.depending on what has to be done. These sets have no user replaceable parts inside them, so trying to fix them yourself these days can not only be dangerous, but if you do not have the right training to work on these solid state sets, can also be alot of guesswork.

My rear projection tv used to have green lines , now the color seems off and now its blue lines... How do i fix it. Color going out??


If colors are skewed or looks 3d it is a convergence problem.

Some sets when the convergence grid is called up will have green lines--green is fixed and red/blue adjusted to it.

To tell you how to fix I need to know brand and model number.

These are typical convergence problems--no two sets will look exactly the same.

Panasonic Model #PT51HZ41E Blue is not converging, red and green perfect. Blue lines move but will not converge have replace STK392-110 checked all resistors what else could the problem be


On my Panasonic PT-56TW53, the down left quarter of the screen has a big colour distorsion. Convergence can adjust blue and red, but green is not able to show a straight line. Is tis a mechanical adjstment? Help would be great.

There is just three lines that show red, green and blue.


It has been my experience with Sonys that those three colored lines indicate that the set is having trouble with the data communication lines. The hitch is that a model as complex as that one has as many as five seperate clock/data lines and if any one of them goes down the set will exhibit your symptom. It will take a professional to track down which line is causing the problem. I've seen audio output IC's as well as tuners cause the problem.

Lines horizonal - seems to be caused by voltage to green CRT


Your green CRT is shorted. To test put your red crt socket on the green and your red on the green. then try turning up red control if the green now works its not your tube. If the same thing happens with the red socket on the green you can be sure its the green CRT if the green works properly with the red socket, then you have a problem in the green drive circuit and not the CRT. hope this helps.
