Go INTO the customer menu and select CONVERGENCE--what you are looking for is will blue or red not move in some direction?
If you find in your case blue OR red is wacked and will not adjust let me know--I can post here start to finish instructions for this repair on this set.....
You only need to be able to know how to solder and get at the chips--you can buy a pair of the chips on Ebay for less than 14 dollars plus shipping.
If you cannot do it yourself--let me know and I will give you options.

Testimonial: "Quick feedback with helpful questions."
if you are handy with screw driver i suggest you remove all cd,dvd or anything you got on top of the unit and remove the back panel from this tv after you unplug the unit of course .first thing you want to do is clean your lenses most time dirt ,bugs,etc and other materials get logged on the lenses also make sure you dont spray directly any cleaning product on the lens make sure you spray a rag or some sort of cleaning towel.
after you finished doing this clean the front panel as well were screen is also clean the silver board thats in there as well.after you finish all of this replace all of the screws and boards back on and give it little while to dry off .turn it on see if u still have the lines if you do then your problem lies in the lenses they might be cracked.
if there not you might have bad electrode or power diode going bad.

Problem is called convergence; see attached photos.
This set uses 2 of the STK-392-110 convergence chips, both will have to be replaced and total parts cost on EBAY will be under 25 dollars.
The good news is I have start to finish step by step instructions for this repair in this set. They tell you everything you will need and exactly how to do it.
They are based on my experience doing this repair in hundreds of sets just like yours.
I will enclose also a photo of what the chips look like.
If you want the instructions let me know and we will find a way to get them to you for free.

This is a JVC board but it uses the exact same chips (black) that are in your set.
