Sounds like you have a back light problem. To verify this, turn on the set, dim the lights in the room, and shine a bright flash light on the screen. If you see the faint picture on the screen, you have a back light problem. You could either have a shorted inverter that is pulling down the 24vdc line, a blown CCFL back lamp, a high voltage short (arcing) from one of the inverter outputs, or a faulty 24vdc power supply

SOURCE: 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.

I just fixed this very same problem. It is the capacitors are the problem. However, I think that if you have some minimal skills with soldering, you can fix this yourself. You just need to take out the system board, then the power supply parts are on the top right. The bad capacitor(s) will be bulging at the top and possibly have some brown stuff coming out. The ones that go bad are 1000microfarad, 10V, however you can replace them with higher voltage. I got 35V caps from radio shack for 1.59 each. You just need to solder out the bad ones and then put the new ones in and solder. Remember that the negative end goes on the side with the bold black part of the circle on the system board. Then just cut off the extra ends of the capacitors. If you are capable of doing this yourself, you will spend at most 6 dollars instead of however much a technician costs.

I've replaced every board on the samsung plasma and still clicks


What do you mean by clicks? Plasma televisions are hot cathode ray, there is thermal expansion that takes place due to heat.

Samsung LN-S4695D LCD WON'T TURN ON BUT POWER LIGHT IS ON ?


I would recommend you get a professional diagnosis. There is high voltage present in the set that can harm you. Being that you never messed with a TV, you could possibly cause more damage to your set. These flat panel TV contain sensitive circuitry. What you are describing sound like a fault with either the power supply or main board.

LED light blinking 6 times and TV won't turn on


When you turn on the power button listen to the back of the TV, you should hear a motor with a high pitch spin up (the color wheel) and then the lamp should attempt to fire. The lamp should make a sparking sound and if it does your lamp is most likely defective. The part number for the lamp is on a sticker on the sode that will say "Lamp Code" on it and will be something like BP96-****

46" Samsung LCD, no sound output whatsoever


First try hooking up a different source such as a DVD player or Cable box and see if you have audio. If you do then check the audio output from the computer. If you do not have audio then make sure the tv audio is up half way and turn off the set. When you do this you should hear the down chime provided you have the chime turned "on". If you do not hear the down or up chime then the sudio circuits on the Main bd are bad and the Main bd will have to be replaced. A quick way to check to see if the audio circuits are working is to listen for the up or down chime when turning on of off the set coming from the tv speakers speakers.

Samsung tv model no LE40R74BDXIXEU TV IS USUALLY


First the main bd controls the "Turn on" sequences". When you press the Power on button the Main bd sends a "Turn on" signal to the Power supply. The clicking you hear is the Power on relay ativating. If the tv does not turn on and the relay keeps clicking then you might have a bad Main bd or there is s shorted board somewhere else in the set. The Power supply can also be bad. Have a trained Samsung tech troubleshoot the set.
