TV power light comes on, but no picture

My tv was working just fine. Then one day I went to turn it on, and it won't come on. The green power light comes on, but the screen remains black. Also when I turn on the speakers, I can hear whatever is on the channel, but again, no picture. Any solutions?

    Hey lone99star, thanks for your input. So I tried with the flashlight/lamp and all I could see was the reflection of the light. I'm almost positive it has to be the Backlight Inverter. What's the trick to fixing them, and is it something I can do myself?

I have the same problem. I now turn the TV on manually and tilt it forward at the same time. This has been working for about 6 months now. I don't know why tilting it forward gets the picture back but that could be part of the problem going on internally. I cannot afford to get it fixed. The TV is only 2 years old. We thought we were buying a good product. Guess Not. Try this.....

Hi cheerlead805, I am happy to help Unfortunatly you have a bad Backlight Inverter. Just to make sure my diagnosis is correct I will need you to test it. Turn the tv on to a point where you have sound. Take a flashlight or a lamp with a bare bulb and shine it on the screen, look vary closely at the screen, you should be able to see a very dark video image. Let me know what you find and I can help with parts and replacement. Please rate this solution. Lone99star

    I have been unable to find the part at a decent price, I did find the inverter for the 4u here is a link

    We will need to take your inverter out and compare them, as long as the connections are the same it will work. Let me know when you would like to get started and we can go into chat for the disassembly.
    Just courious though, why are you so sure it is the inverter? Like I said before you should be able to see a dark image when you have sound, you could hear the tv when you shined the light right?

Tv does not turn on


If green light flashes more than 8 times, it could be as simple as repairing or replacing the power supply. Unplug the TV ,remove the back. Look for bulged or leaking capacitors on the power supply. Do it yourselfer? only if you have soldering skills, or purchase replacement board. remember, used boards are just as old as your failed board, buy new or rebuilt, Good Luck

Hi. i believe this to be either of these three problems.
1. Power: it could be that there is a problem with the power electronic element(s). the solution is to go see an engineer.
2. Screen: if the television uses LCD display, it could be a problem with the liquid in it. Solution is to see an engineer.
3. Sleep mode: the TV could be in sleep mode which makes the screen go blank until removed from sleep mode. Solution is to read the TV's users manual to see how to wake a sleeping TV. Get back.

replace the sustainer boards should correct this problem. New sustainer boards may cause red and green pixilation. If this happen, replace control board and TV is as good as new.
