Unplugging it from the outlet for about an hour to let it reset itself first, if it still does not work then It may be in the safety shutdown mode due to short circuits in the power supply or in the backlight inverter board, you can try disconnecting the power cables to the backlight inverter board to see if you can get the TV to come back on with sound but no pictures.

If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

When TV is turned on, green power light comes on and picture starts to come on, after a couple of seconds the picture goes out along with the green power light and the red standby light comes on and blinks...


Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.
  • No video, Power light is on or blinking.
  • TV is making a clicking noise.
  • TV takes a while to come on
  • Screen is very dim or flickers.

Again, You can get a power supply repair kit with the parts, detailed instructions, and support from sites such as www.TvRepairKits.com . Or just click here to see more details on their kit.

Here are pictures of capacitors...Notice that the ones below look bloated. They have failed and will need to be repalced.
