Do you have sound? If so, dim the lights in the room and shine a bright flashlight on the screen and see if you have a faint picture. If you have a faint picture, you have a backlight problem. On most of those sets, the backlight inverter is combined with the power supply so that power supply/inverter board will more than likely be the culprit!

Dim the lights in the room, turn on the set and shine a bright flashlight on the screen. Do you see a faint picture? If you see a faint picture, you have a backlight fault. Could be several things, you could have a bad backlamp, defective inverter, defective 24vdc power supply, or a faulty main board. I would highly recommend you get a diagnosis

You have a backlight fault, to verify this, dim the lights in the room. Turn on the set and shine a bright light on the screen. Do you see a faint picture?

If you can hear sound then the problem is most likely your LCD screen. look at the screen under a bright light. if you can make out a faint picture then your backlight is out. Usually this means your screen needs to be replaced. replacement screens can be found on ebay for about $25

If you cannot hear sound or see anything on the screen then you have a more general motherboard failure of some kind and should bring it to a service technician.

sounds like you are going to get a red ring soon...your video card is going bad

Mainboard damaged.

There could be 2 failures with your TV:
1. The power supply might no be providing 24 volts to the back light inverter board or the voltage is low.
2. If the voltage is normal then is more likely a defective back light inverter board.
The best way to know if you have a back light inverter problem would be to shine the light from a flash light near the screen and observe it from a 45 degrees angle and you should be able to see a fainted image. No image at this point might mean a power supply failure. If the image is there but fainted, then the back light inverter board is defective.
Let me know if you require further assistance.

I think you have a short somewhere inyour set most likely the horizontal output transistor which may have shorted by the high voltage transformer going bad. The faint ticking sound that you hear is the power supply trying to start but the shorted load won't let it. Stargazer
