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 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.

Sounds like a warped color wheel which is part of the light engine assembly. That is the assembly which has the bulb.

SOURCE: samsung tv just clicks when turned on comes on

It could be a faulty power supply (capacitors). To all who are having power supply issues: Samsung is now acknowledging a problem with faulty capacitors. I called 1 800 726-7864 and they said they would repair certain out-of-warranty TVs if the problem is related to the capacitors. I just called and they are sending a service rep out to diagnose the problem

You need to replace a few capacitors in the power suply. The tops of them will be swollen up instead of flat.

You have a problem on your Power supply board, possibly a bad capacitor or loose connection. You can look hard at your power board and check for these things or replace it from places like shopjimmy.com or discount-merchant.com etc

When turning on the tv it takes a long time and you can hear it clicking trying to come on


Sounds like the early stages of an eventual power supply failure. Start asking around for a reputable repair shop in your area.

Samsung LNT-4665F won't power up properly


There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
