I had a similar problem, except it was at the top not the sides, of a
Princton Graphics monitor. I assumed it was a bad electro in the
vertical but these checked out fine. Turned out to be a 3.6 volt zener
in the yoke return was opening intermittantly. I'm not saying you have a
defective zener diode only that the problem can turn out to be caused by
something completely different than what you first guessed.
Q. From: Q.E.D.
Q. I just purchased this TV last weekend at Best Buy. I had to return
Q. one because the case was cracked on the right side (obviously damaged
Q. during transit). The second set is physically intact but exhibits a
Q. pattern of very faint vertical bars (about 8 to 10 bars) along about
Q. 1/10 of the left side of the screen. The bars are especially noticed
Q. on plain solid color backgrounds. Going into the service menu to
Q. adjust overscanning only brought in a few more bars from the
Q. previously hidden screen area that was being overscanned. Reducing
Q. the overscan area compressed/tightnened the faint bars/lines making
Q. them even more noticeable. I noted the bars moved along the screen
Q. with the adjustments to lessen overscanning.
Q. I realize this is a rock bottom price TV but even so the TV shouldn't
Q. exhibit this picture defect. What could be the cause of these lines?
Q. TIA
.... High voltage can give a dangerously uncomfortable discharge.
