The simplest problem would be the failure of the backlight.

In case you don't already know it, there is one, and they may or may not last forever.
Also, there is an extra power supply to produce the high voltage the lamp needs to fire that may have failed.

Sometimes, you can look at the screen from an angle to see if there is any sign of movement.
If you can see program material causing a change in the faint image, then you can be pretty sure it is one of the two problems mentioned.

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.

pls rate me!

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.

if you can do soldering work, replace two 1000uF10v bulging capacitor with 1000uF 16v or 25v in powersupply board. you will save $200.

Check for bad capacitors in the power supply. The capacitors will be bulged on top. Typically there will be 3 or 4 caps with this problem. Thanks for using fixya.

Sony KDL-46XBR4 46 in. LCD flashing light. Light flashes red 8 times pauses


How many times this standby/power light blinks at one time switch ON? Count it carefully. These blinks are fault indication, and known as blinking codes. From the number of blinks occur at one time switch ON; you can get an idea about the faulty circuit stage inside the TV. This will make repair easy. For more information, check the link http://electronicshelponline.blogspot.com/. If the blinks continues, and non-stop, the fault should be with its main system control IC, and with the memory IC. Try this link too.
