Question about Televison & Video

Open Question

Our KDL40E4500 LCD TV has developed 2 pairs of thin short flickering lines in the upper half of the screen. The lines are at the extreme left side and about 1/3 from the right edge. Initially there were only 2 lines near the top of the screen but after a week there is a second row of identical lines a little below the initial lines. I have tried a pixel fix program but without succes. Naturally, the warranty expired last month. Anyone have any ideas on what this might be and how to best fix it? Other than this the picture is perfect.

This maybe the symptom of a bad Panel. One Vertically This line is 99% bad panel. Call your warranty provider or SONY tech support if purchased under 2 years.

What you're describing is usually the result of an improperly seated connector. With the power disconnected, open the tv and locate any connectors between the LCD screen and the driver circuit board. Unplug them, and reconnect it assuring it's properly and firmly seated. Be careful when handling these cables as they tend to be quite fragile... take your time.

SOURCE: I have a PS42A410 Samsung that has developed a 10cm black line

Your control board needs replaced most likely. Does it work fine on a cool morning when you first turn it on, then develops the line when it warms up? Good indication it is the control board.

SOURCE: SAMSUNG LE40M86BD very thin black line

I have the same problem with the same model tv, just over 2 years old, and out of warranty, you should expect more than 2 years life from a tv costing around £700, i have just had an independent inspection done confirming a manufacturing fault rather than human intervention, and clearly not fit for the purpose for which it was sold, and sent it to a large retail park outlets customer service dept, i have been assured they will look into it, my 15 year old sony 32 inch wide screen crt still performs as well as it did when i bought it, but it is the size of a small family car so not easy to lug around, i guess they just dont make em like they used to,

White line across screen


If your LCD TV or monitor has stopped working, or is displaying one of the following
symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can
examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life
of your monitor or TV by several years.

Take it to a repair shop.
