Unit has lost verical deflection. Most likely and IC has failed and will need a tech to diagnose and repair.

I had the same problem on a 36" Hitachi TV about 7 years old. After reading comments on this and other pages I went and bought a soldering iron not knowing what I was going to do with it.
After trying to find a loose connection with the power off- with no success, I then tried with the power on. Not the smartest move, but I was able to find the problem.
If you follow the colored wires (blue, green, red, yellow) from the back of the tube they will come together at a connector that plugs into a card at the bottom of the set. That connection was no secure. Since reseting that connection I have had the clearest picture since puchasing the TV new.
I am sure it is obvious that I don't have an electronics background, and I don't have an explaination as to why this worked. I just know it did. I hope this helps someone.

TV screen has a thin horizontal line in center


this will only help until the next time it is out of alignment but if you slap the side of your tv about where the line is it should straighten out but there is no telling how long it will stay straight......My sons tv was doing that and i had a tv when i was young that did it that is what my mom told me to do and what i told my son to do and it works.... the problem is an alignment or conection problem from dust most likely.
