It is most likely the TCON board (located at the top right against the LCD panel). When these boards have problems, they can act up when cold or warmed up.

You will want to check with any extended warranty company you might have, or Sony's part website for the availability of the TCON board.

The problem here is, sometimes those TCONs are not made available separately and need to be replaced with the screen.

If you have to replace the panel, buy a new tv. You'll save yourself a costly repair.

SOURCE: My SOny Bravia 40 inch LCD TV has a vertical line

Hi,

It could be 1 of 4 things:
1. One of the ribbon cables has worked itself loose (Simple Fix)
2. One of the assembly boards maybe faulty
3. The driver board which feeds the panel maybe faulty
4. The panel is faulty

The driver board in the UK costs approx £70 and approx £35-70 to fit it if this is the fault.

All other parts are between £80-160 and approx £35-70 to fit it if this is the fault.

The panel will cost approx 50-75% of what the TV was worth when you bought it - "Repair versus Replacement"

Thanks

Color separation ~ Insignia 32" NS-LCD32


1. Unplug unit from wall for 3 minutes;
2. Press & hold Power button for 1 minute;
3. Plug in unit.
OR:
1. Unplug for 3 minutes.
2. Plug in unit.
3. HOLD Power Button as unit starts ... hold until the unit flickers on then off twice.


This effectively returns the components to factory specs, much like resetting a computer. It offers a *temporary* fix, lasting 45 minutes to hours. All depends on the unit.

Mom has an Insignia 32" with the same color separation problem, which worsens as the day progresses. Best results achieved while television is cold.

Dust in the unit could contribute to the problem ... try to keep the unit dust free as possible.

Vertical Lines on Sony Bravia TV.


I'm afraid, its problem of LCD Panel (screen).
LCD Panel replacement is only solution for this problem and will cost you 70% of TV price, please contact nearest Sony service center for LCD Panel replacement.

Verticle lines for picture


You need to describe these lines better. Are they moving or stationary? Are they very fine lines with sharp edges or are they more like bands with soft edges? How many lines do you see, and how wide are they (compared to the screen width)?

Fine lines that are stationary: defect in the electronics causing a vertical row of pixels to be dead or stuck. Can only be fixed by replacing major parts.

Broad lines with soft edges that move: could be electrical "hum" interference. Make sure you are using a grounded (3-pin) power plug, and that the outlet is properly wired. (Take the TV to a another location and see if the problem goes away).

Make sure you don't have fluorescent light fixtures nearby--they can interfere with the picture if the bulbs or ballast is defective. Could mean tecon board or display is bad which means replacing both in a sony if they are bad i recomend buying a new tv because it is not cost effective to replace these.
