Hi. 1/4 screen. Horizontal or vertical ? Makes an important difference. I need more details, like typenumber f.i. Also, you must be able to carry out repairs on this electronic circuitry. Otherwise it makes no sense talking about components etc.

I also have a 35" JVC that just started doing the same thing. Did anyone post a fix?

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

If you have a DVR too, there is a pound (#) button on the beside the zero on the DVR remote that stretches my screen off and on. Try that.

A bright Horizontal Line indicates failure of teh Vertical deflection Circuits.
Get a competent Technician to have a look.

If the horizontal lines going through the picture are fine white lines, then I would suspect the picture tube as having a heater to cathode short or some other problem. Since some sets have had a 3 year warranty on the picture tube, you may be lucky unless the labor to replace the tube is more than the set is worth. Sanyo is usually not a good name in consumer electronics anymore, so if you're looking for a replacement I would look elsewhere.

It sounds like a vertical deflection problem. You mentioned you had a white HORIZONTAL LINE in the middle of the screen. If this line runs from left to right across the screen it's in Verticla deflection. If it runs from top to bottom, it's in Horizontal deflection. I am assuming the problem is a Vertical deflaecion problem. The repairs necessary are most likley to replace the vertical capacitors or the verticla deflection chip.
Good Luck

This is usually caused by a problem in the Horizontal Output section, around the Horizontal Output transformer usually a capacitor or diode going or gone faulty... the line you see are the Horizontal "Retrace" lines that are useually "Hidden" when the circuit is OK..

The unit most likely has a short in the horizontal section and would require repair by a service center. Go here to find a JVC repair center in your area http://maps.jvc.com/cAscList/
