This is an easy repair if you've ever soldered and would not be too costly for a repair shop to do it for you. The problem is a bad Vertical Output IC (usually mounted on an aluminum heat sink with the part on it labeled LA78?? ) and 1 or 2 bad capacitors. Some times you can even fix the problem by re-soldering the contacts of the IC- To find the IC follow the 4 wires that come from the Yoke (which is a contained coil of wires slipped over the neck of the picture tube(s)) back to the board. 2 of the wires go to the horizontal o/p and 2 to the Vertical o/p the thinner gauge wires are for the vertical.

LG 32LH30 LCD TV Problem


IMO Seriously for $119 it's not worth it.
However, it does sound like a capacitor problem
If you are "Serious" about fixing I'd find a TV repair Forum.
Else I'd go here and get a new one.

There are white thin horizontal lines across the top 2" of Toshiba 27DF47 TV. Can this be repaired and how much would this repair cost?


Check and replace all the electrolytic capacitors at its vertical output section circuit. There will be five or 6 of them. Replace all.

You had parts in the vertical deflection circuit failing, most common are the vertical output IC and possibly several capacitors also in the same circuit.

Vertical white line down centre of Soniq PT42SH plasma TV.


One of your "X" buffer boards is defective. In Panasonic plasma tv's they are located at the bootom of the set and connect directly to the plasma diplay panel via a thin ribbon cable. The board you want to replace will be directly in line with the discolored vertival line in the picture. The part number is on the circuit board and usualy starts with "tnp..." or "txp..."

Insignia 32" TV Thin line across screen 1-2" from top


The original white line problem was caused by improper adjustment of the vertical size for which there is an internal adjustment. The current problem could come from two different sources, one an adjustment again, the other from a capacitor that is losing capacitance and gaining losses; = sick.
If you are fortunate enough to have a surviving TV repair in your area, none of these problems is expensive to find or correct.
Don't be surprised to find the only TV shop operating out of a messy garage since those of us doing this kind of service are dying off and the price one can charge for labor has shrunken to the point that a real business address is too expensive to have.
