Question about Televison & Video

1 Answer

Had the LCD TV For 5 Years, no problems, then just before going to bed i was about to turn off the tv when the screen went black but sound was fine. I switched channels and you could hear the channels changing and sound still ok, turned tv off. Left power to tv on with Sky digital box. Put tv on this morning, still the same. I have now switched everthing off to tv. What could be the problem? Thanks. Dean

Your problem can be related to either LCD backlight inverter failure or T-con board failure. Please turn on your tv, darken the room and see if you notice a dull glow on the screen. If you see a dull glow then backlight is functional and the t-con is dead. Otherwise it can be a backlight inverter failure(in some cases the backlight itself). In that case I would try replacing the backlight inverter board and hope its not the backlight as the backlight is embedded into the the panel and the only way to replace it is to replace the panel.

I have an LG model 37lc2d the screen is black but has illumination and no sound at all and the green power light flashes 16 times upon powering up?


Things to check: Make sure your TV is set to the correct input.
I DK about the light flashing 16 times but that could be a stuck key on your remote control. If you can, urn off your remote and try turning on by hand and going through the "INPUT" choices to make sure you have it on the correct setting. BTW, if your TV is 5 years old, you'll make the money back in no tie if you get a new "Energy Star" TV. The new Energy Star TVs run on very little electricity compared to 5 years ago.

47" plasma 1080p ... screen went black , sound


Plasma TV's have a shelf life. By that I mean the screen is only good for so many hours depending on the model. Most likely, you have burnt out the screen and the set will need to be replaced. The good news is, plasma TV's used to be better than LCD but that is no longer the case. You can get a very high quality LCD TV for a very low price now. Also they use a fraction of the power and don't generate all of the heat of a plasma.I'm sure this is not what you wanted to hear but the reality is that ALL plasma TV's do this eventually, and it is something that most salesmen back in the day didn't bother to tell customers. If you have an extended warranty, you may be able to get it replaced.

No pic but sound :/


You are having a high voltage problem. Quite possibly in the horizontal deflection. I would check the horizontal output and regulator transistors.

Black screen with sound. Problem on every channel.


Sound no picture or shut down Power led starts green then a short amber then turns RED . If your power supply can be confirmed to be go you have a bad Inverter board. Per the manufacture this part comes only with the panel . Not cost effective . But if you go to
lcdparts.net you will locate an inverter for $ 169.99 . I had the same problem and the inverter repaired the set . Note there are similar error codes but from what I can see from all of your complaint I do be leave that your Inverter is bad . Good luk
