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.

Please check what t- con board is similar with your tv board to order it. If you are not handy with electronics stuff repair then local tv repairman will help you to replace t-con board that might solve your tv picture problem.
Thanks.

My TV is (same model is doing the same thing). The manual shows that the 3 blinking lights indicate "LED may be defective. Please contact a certified technician."

Note: When I power my TV off (unplug) and back on, the TV's left indicator light is solid for less than a second ("Stadby state") then the right light blinks ("The picture will automatically appear in about 15 seconds") for about 15 seconds. This pattern is repeated numerous times (I think it was 5 times). I believe the TV must be failing some power-on test. Aftere failing 5 times it gives LED may be defective indication.

Take it back!!!

This is a bad sign of more issues trust me after 15 years in the biz. If you got a chance take it back and stay away from that line

is the picture clear when on? if yes, does the screen go black after a few seconds. if yes, sounds like you need a back light inverter!

Using a monitor
1..connect computer/media center to your monitor,
2 click on nvidia nview display settings,
3, select the current display tab and samsung,
4 then apply,
5,then when the confirmation box appears click yes within 15 seconds.

Using your samsung.
Attach a scart to your media centre, from your t.v with the p.c cable still attached, turn over using the source button until you can see a pc picture on your screen (EXT1or2), do steps 2 & 3 THEN move your cursor to the apply button (do not move the cursor from this position), press your source button till you get PC channel (which has no picture yet) then press your mouse button to apply, ( your picture will flicker on), and before the picture goes confirm with the yes button. You now have light! eureka :)

If it is only 6 months old you probably still have a warranty. This is definitely a hardware issue, and unless you are comfortable taking your new TV apart, I would contact Samsung for repair.
