Thanks for the question. My name is Dan.

Just a couple questions so I can get a better idea about what's going on here.

1. What's the model number?
2. How old is it?
3. Do you plan to repair this yourself, or are you just trying to figure out what may be wrong and if it's worth professional repair? If you want to do it yourself, do you own and know how to operate a voltmeter?

It is 4 year old.

I do not plan to repair myself just would like to know the possible cause of the fault.

The model Number is LE 40M 86 BD



Kind regards

Turn the TV off and let it cool off for a while. Then grab a friend and turn the TV on. Then, apply a twisting motion to the screen (like you're wringing out a towel)... see if that will clear up the affected areas, even if it's just for a second while the pressure is applied. It's not a permanent fix, but it will help me narrow down the issue.

You can also try squeezing the TV’s bezel (plastic piece around the screen) near the affected area. Again, not as a fix… just a test.

Let me know.

Hi - Sorry for the delay. Your suggestion did not work. Have been in touch with Samsung who advise the fault is with the LCD screen. Needs a new one however they are no longer available. It is a chuck awe3ay job for the tip. Just ordered a Blaunpuct Tv to replace it.


Many thanks XXXXX

Hi Ray,

Yes, I suspected a defective LCD panel... that's what we were testing for. I'm glad you were taken care of. Let me know if you need anything else.
