Question about LG 32LG40 32 in. LCD HDTV
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.
