Line faults & possible causes to LCD & Plasma screen are given with illustrations. You can get an idea about the fault to an extent. Faults to all LCD & Plasma screen are similar, irrespective of its brand and screen size.
This line is due to fault to horizontal sweep section. Replace all the non-electrolytic capacitors with new ones. Replace the horzontal output transistor too. Check this linkhttp://electronicshelponline.blogspot.com/ to get more details.
At first the picture is ok, and then distorted with horizontal lines i thinks. If the horzontal lines are parellel acros the screen, with an inch apart across the whole screen, your tv needs screen adjustments. Screen voltage may be high. look into the crt base also. Change it first. These also not resolve the problem, LOT may be faulty, with respect to screen focus pack. May need replacement. Try first setting screen voltage to a lower settings and observe.
You will need to replace the Horizontal IC around $80 bucks for the parts and labor. What happen here is when the Horzontal ic gives out the screen basically folds to the middle. Do not shoot the messanger here but have the TV looked at by a professional locally.
I hope this was Very Helpful to you today please leave your feedback and ratings.
The LCD Panel must be replaced to fix both problems. The cost in doing this would exceed the value of the set. I recommend not putting the money into it.
