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.

The TV, most probably, the display circuit or the display itself has developed dry solder/components leaking and the TV needs attention by a qualified service technician.

Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Pull up older posts.

When CRT TV's show only a white/bright line horizonatlly It is a failure of the flyback Transformer. Not all that costly to repair. Your old TV will probably still be working when all the latest plasmas and rear projections have been laid to rest. Fancy junk TV's dont get any better programs than those old reliable ones

Please rate my help++++Thanks for using FRIXYA

your tv has a vert problem

it sounds to me like your tube has gone , go to your local tv repair shop and order a new tube its quite cheap to do so and they should be able to get it you quite fast.

vertical output ic needs to be resoldered. careful leaving that bright line displayed on the screen as this will cause a permanent phosphor burn into the tube. this can not be corrected once burned unless you replace the tube. mch

This is cauced by a collaspe of the vertical output circuit. Normally a relatively easy/quick fix by a skilled repair tech. If you have a nice quality set that is less than 7 years old, it might be worth fixing, otherwise, you might want to consider getting a new one.

Give a call to a local service shop and tell them what TV you have and the problem and see what they provide for an estimate to repair, it might be worth doing and it might make your decision easier to go buy a new one.

Sounds like the flyback transformer is bad. couple of 100 dollars if it is that

HEY WEGA-YOUR SET HAS A BAD VERTICAL OUT IC AND ANYTV GUY CAN REPAIR THAT FOR A REASONABLE (COMPARED TO REPLACEMENT OFSET) COST.JOE TV
