New GE 32GT740 32" TV...Faint Vertical Bars on Left Side Of

[Q.E.D.]

I just purchased this TV last weekend at Best Buy. I had to return
one because the case was cracked on the right side (obviously damaged
during transit). The second set is physically intact but exhibits a
pattern of very faint vertical bars (about 8 to 10 bars) along about
1/10 of the left side of the screen. The bars are especially noticed
on plain solid color backgrounds. Going into the service menu to
adjust overscanning only brought in a few more bars from the
previously hidden screen area that was being overscanned. Reducing
the overscan area compressed/tightnened the faint bars/lines making
them even more noticeable. I noted the bars moved along the screen
with the adjustments to lessen overscanning.

I realize this is a rock bottom price TV but even so the TV shouldn't
exhibit this picture defect. What could be the cause of these lines?

TIA

Sounds pretty normal for that particular design if they are very faint and
only noticeable on solid color backgrounds.

It is simply cheap design of scan derived power supply filtering.

Take it back and go buy a better tv set and decide to live with whatever
engineering compromises any tv set you pick will have.

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.

.... High voltage can give a dangerously uncomfortable discharge.

The very low end sets tend to not be as perfect. Since it is a new set,
I doubt there are failed components to this extent. I would suggest you
pay the price, and buy a higher end model.

The low cost GE sets are so low in their level of value to the
manufacture, that when the customer brings it in for service under
warranty, they change the complete main circuit board inside. The old
board goes to the crusher. Many of the large retailers give the
customer a new set out of stock, and send back the old one. The returned
sets have the main board changed, and then they are resold as
"refurbished" sets.

If you want a very good deal with exchange warranty, there is
Wal-Mart's, Sears, Future Shop, and other similar large vendors. They
have a very high degree of customer satisfaction. This is better value
than mail order for a TV set! Check in to their policy for your area.
Warranties can vary in different countries and states.
