If the white line slowly increases in size meaning the picture get larger over time then the problem is capacitors in the vertical circuit are most likely bad. Capacitors will dry out from heat over time and not be effective. These will have to be replaced.
However if the line suddenly disapears and the picture is normal after a period of time then you may have a loose connection on the printed circuit board.

Good day.

Refering to to mr walts inquiry and if it is, maybe you are having some issues in your vertical circuitry. It may be loose that it needs to be resoldered and other filter capacitors within the vertical section.

Straight line in the middle of monitor. picture srunct


This is called vertical collapse and the most common cause is a failure of the vertical IC. If you can update this with the model number, I should be able to provide the part numbers and costs for the parts required to fix this. Also, if you intend to repair this yourself, please indicate thtat as well. The parts will cost around $20 or so.

Panasonic CT-27L8SG displays gray screen and white hoizontal line


Is it still under warranty?
If not I would find a good TV Service Shop and have them check out the power supply as there more than likely a 'Capacitor' much like a battery that is going bad.

Tv goes to straight line in center of picture then


It happens when Vertical deflection stops as Vertical Out IC becomes hot or does not get vertical signal.
Please check electrolytic capacitors and dry solder joints in vertical out section in TV.
