Also, if the volume is up the T.V. turns off; this started when the lines appeared.

Vertical lines or streaks
Check for a leak where light might be entering the printer.
Check for circumferential scars on the photosensitive drum. If scars are present, replace the
drum cartridge if the line goes through all colors.
Check for circumferential scars on the upper fusing roller. If scars are present, replace the upper
fusing roller if the line goes through all colors.
Remove the imaging drum and inspect main charger or imaging drum for a contaminant, such as
a fiber, if the line goes through all colors.
CAUTION Do not expose the imaging drum to light for more than 15 seconds. The drum is light sensitive, and
exposure to light can cause permanent damage.
Vertical black lines
The toner cartridge is defective.
The toner cartridge is not seated properly.
The fuser entrance is dirty.
The fuser has scratches on it.
This might be a repetitive defect. If so, the lines will repeat at a consistent interval down the page.
The printer needs to be cleaned.
There is a problem in the heating element.
Vertical white lines
If white lines or streaks appear only in the black areas of the printed media, print several
configuration pages to clear the anomaly. If this does not clear the problem, check the sleeve
surface to confirm the defect, then replace the black toner cartridge.
If white lines appear only in a particular color, try printing several configuration pages to clear the
error. If the error does not clear, check the sleeve surface to confirm the defect, then replace the
defective toner cartridge.
There is a lack of toner or the toner cartridge is faulty.
There is dirt in the laser path.
The fuser is defective.
A mirror in the laser scanner is dirty.
This sounds like one of the driver boards at the bottom or top of the screen has an intermittent fault. The set will have to be taken in to a service centre.
Take your set to a qualified tech you have a bad vertical ic or some cap around the vertical section is not filtering the voltage properly and your deflection yoke could also be bad.good luck.
