Make sure both convergence output IC's get replaced. After replacement convergence adjustments may need to be done. These can be pretty hairy, so don't try the repair yourself.

you have lost the convergence IC`s in your set, this really isn`t a diy repair unless you are very proficient in un-soldering and re-soldering components, once replaced there will be an alignment procedure as well that will require the service manual also, if you have more questions feel free to ask away, video-tek

Tv is yellow orange color what is problem


The model indicated does not have a "bulb" as it uses 3 picture tubes.

Examine the picture with color set at zero---stand back and look= if the screen has a mostly yellow (all or part of the screen) you have bad Glycol in the blue picture tube(if need explanation ask) and a look in the lens of the Blue tube will confirm this.

If able with back off and a small mirror look in each lens--red picture, green picture and blue picture.

If the Blue looks like a floodlight with little or no image--bad glycol in that tube.

Having a big yellow spot background in the middle of the picture.


Hi , it seems you are experimenting a light engine problem.Here's how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine. Have a blessed one!

Convergence Problem


sounds like 1 of the convergence chips are gone theres 2 of them and better off replacing both as the other would just go a month down the line there might also be a resister or 2 gone, the price for that kind of job is around 150 +vat.

hope this helps
