Hello

Welcome

So just to clarify it does flicker as well using something like a DVD or blu-ray player?

Is it the brightness that flickers?

Is it a fast flicker like a strobing?

Customer: replied 11 months ago.
It flickers with all inputs. Even menus. It's not brightness. Picture doubles and moves and flickers, and it's fairy fast.
Expert:  Anthony_Infotech replied 11 months ago.

Hi thanks for the further info its a bad t-con board, this board drives the LCD panel, if the sets OWN menus are doubling \flickering then that is conclusive, do you think you can replace this board yourself?I will provide all the support and on-going support you need to do that, just to emphasize this is a plug in board and usually moderately easy to get at.

Let me know please thanks

Was this exactly the SAME issue as before?or something different

Exactly same issue as before.
Expert:  Anthony_Infotech replied 10 months ago.

It can only be the panel (screen) are you sure the set has not had a bang?looks that way , you see the menu is injected directly into the t-con board and onto the panel so if that is affected its either t-con or panel itself in most cases its t-con but looking at that makes me think its suffered a physical knock?also

Let me know how old the set is as well please, it looks like a 2011 or 2012 set?

Anthony

Customer: replied 10 months ago.
The TV was mounted onto the wall, so I'm pretty sure there was no bang. It developed over time. At first I was able to turn on and off a few times and it would stop. Now it flickers all the time. Yes I think it may be 2012 or so. Is it possible to buy a panel?
Expert:  Anthony_Infotech replied 10 months ago.

No its not an option to buy and replace a panel in an LCD TV due to costs it would equate to two thirds the cost of the set to replace as new so for a 4 year old set its not an option and even if it was less than 4 years still not an option however I advise people to complain to the manufacturer via the website. The panel is the display screen.

You also have to be careful with mounting a big set on the wall because what can happen is over time the panel can warp and this stress can damage the panel depending on how its mounted.

I am sorry for this dismal news

Let me know if you need more help
