    On the main menu where I would normally watch satellite there is a stretched out X in blue, red and green colors. When I switch video channels then there is only blue red and green on the right side of the screen. What could the problem be and how to fix it?

You have to have the convergence ICs changed out. Possibly also a few resistors near the ICs if they burned up too. The chip is a STK392-040.

For that type of problem you will probably want to call a local tv repair shop and set up a service call. Average price is 60-80 dollars to have a professional check the set and provide you with an estimate. To me it sounds like maybe the vertical circuit has failed if you have colors across the center of the screen. Also there is probably a resistor and capacitor that need to be replaced on this one. Usually it is a repair that most shops will be able to handle for less than 1/2 the value of the unit which is the breakoff point for most people. I wouldn't suggest trying to self diagnose this one without test equipment. Good luck, Russmann..

The cost I don't know, but this can be fixed. There are generally 3 lamps in projection T.V.'s, Red, Green, and Blue. They have to be aligned for the TV to project a clear picture. A credible TV repairman should be able to fix it. Depending on if it's new enough to be under warranty they may cover it as well. Really the only reason to get rid of it is if you want to get a new TV anyway. Depends on the cost of having the lamps aligned.

Convergence is when you aim all three of the projectors, your tv has three, so that the images they produce all line up with each other. This usually doesn't generate a white line across the middle of the screen though, there is a button on the front panel of your set that automatically converges the three projectors, you can try using that.

This is not an "STK" problem. Your problem is VERTICAL. You need to check your vertical chip for damage CN301 and check around it for any bad parts or loose connections. I've seen loose connections on the chip itself cause it to self-destruct.
