White Screen w/ White Lines, Sound On, Turns off after 2 or 3 secs.
Hi
If you mean thin white lines, this is is an indication of a problem in the Horizontal Drive ckt. most likely the Damper Diode has opened or shorted, this would cause the visual symptom and then the set would shut down, unfortunately this is a problem best left to a qualified technician to repair, hope this helps.
It is not a single horozontal line. When the TV is turned on several diagonal lines(gray and white) come on the screen then the TV shuts itself off a few seconds later. Thanks
