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.
Check the cables, connectors and connections.
Take it to a repair shop.

Yes, I had the same problem, it happened after 14 months of
my purchase, or just 2 months after expiry date of warranty. But remember they
have 60,000 hours warranty on screen and this fault is part of screen (no
picture J it
is screen problem), I called LG, first they did not accept the claim but soon
after I mentioned that I have done many research and this is very common
problem due to use of faulty part or unreliable design, and if they don't fix
it on their cost I will take legal action, one of the supervisor contacted me
and after saying LALALALALALALALALALA accepted to send someone to fix with no
cost. But I have found out they did to many others whom take this mater serious
so it was not just me alone J They are aware of
using faulty part is some ranges of their products and now this common problem
appears, LG don’t like it and wants to somehow get away. ((((((((((So don’t let
it happen))))))))) some of us paid around $5000 to $7000 when this TV came out,
recently price went down to around $2000. CALL THEM and ask FIX or COURT? For sure
they fix it for you free of charge J
Imagine how much would it cost them to
recall all TVs which they know is faulty?
Enjoy

Likely the "main" board that processes all digital information in and out of the set---Not likely to get fixed in the home or be a do it yourself repair.
You might want to call Samsung with the model number to see if this is a known issue in this model or not.
