I had the same problem - found the specific problem on forum boards. Fixed it myself for less than $20 with no electronics experience. Samsung installed bad capacitors...undervoltage for the LCDs from 2005-2007 (some models).  You can replace the capacitors yourself...go to http://www.tech-report.net/forums/viewtopic.php?f=37&t=67237  or  http://techreport.com/forums/viewtopic.php?f=37&t=62360  for instructions.  Good luck!

    I had the same problem with my samsung, I started having the problem in April 10, 2011 I called Samsung and they are going to replace it for free (my warranty was already expired), they said they are having problems with certain models and they will gladly replace the capacitors for free. I will repost once it is fixed.

The most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

My samsung lcd wont turn on just a clisking sound and red light flashing in corner


Most likely bad capacitors in the power supply.
Samsung LCD units have the power board in the middle of unit. You might see 2 or 3 electrolytic capacitors bulged at the top where it should be flat.

Samsung LCD tv wont turn on


what the full model number of your tv?
the clicking sound is the result of a faulty power supply, some capacitors(blown heads) on the power supply for the output voltage rail of the mains board need to be replaced.
