IMAGE STICKING ON LCD??

IN A 32 INCH LCD (LG) WHEN WE CHANGE STATIONS FOR EXAMPLE, THE PREVIOUS SCENE REMAINS STUCK ON THE CURRENT PICTURE FOR ABOUT A MINUTE THEN GRADUALLY FADES AWAY.

FOR PDP WE HAVE SEEN SUCH CASES A LOT AND REMEDY WAS TO ADJUST VOLTAGES.BUT WITH LCD, WE THINK IT CAN BE A MEMORY DEFECT OR SOMETHING OF THE TIME CONTROL.

YOUR COMMENTS MUCH APPRECIATED.

It will need the software updated especially as it's over two years old. The best thing to do is contact the LG service centre to have someone call out & update this for you.

If the signal has not changed, then the problem is internal to the set. Given that this unit is only a few months old, it is still under warranty. Request a warranty repair. This should be repaired or exhanged at no cost to you. It sounds like the digital processing section is defective.

Unfortunately this is an unrepairable problem called screen burn.

This happens commonly with old displays and can only be fixed by replacement.

Hi, That is because you might have turned on the environment mode. The TV changes the brightness automatically depending on the light in the room. Hence you are experiencing this. You can turn it off in the TV setup menu. Regards.

That can be the T-CON board failure or main board. It can be heat relate so you will need freeze spray for electronics troubleshooting to cool down the T-CON board first to see if it starts working again.
You should also check the power supply first to make sure it does not have any bad caps and the DC output voltages are OK.

Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.

  • No video, Power light is on or blinking.
  • TV is making a clicking noise.
  • TV takes a while to come on
  • Screen is very dim or flickers.

Again, You can get a power supply repair kit with the parts, detailed instructions, and support from sites such as www.TvRepairKits.com . Or just click here to see more details on their kit.

Here are pictures of capacitors...Notice that the ones below look bloated. They have failed and will need to be repalced.

Picture is frozen


There is a button on the lower part of the remote that is a "freeze" button, it will freeze the picture, or capture a still shot. Try pressing this button to "unfreeze" your picture.

Unfortunately, this is a very common problem with LCD televisions and some plasmas as well.
This is what the industry calls burn-in. That image is on your actual screen as opposed to it being caused by any other component in the tv. Really there is no convenient remedy short of replacing the actual LCD screen which can be done. Even by embedding another picture to lessen the effect of the burn-in would never restore the picture to its true quality. Good luck and God bless you.
