LG LED TV has no picture (black screen) but still has sound - can it be fixed?

[jreddy]

My 32' LG LED TV has suddenly lost picture! The sound is alright but the screen is pitch black. After switching it on the picture flashes for a second and then the screen goes completely black. I have unplugged everything, tried to reset it, no good.

PLEASE HELP!

Yes, it can be fixed, just about anything can be fixed unless you threw it off your roof and then ran it over with a tank. Is it worth fixing? Probably not for a 32" TV, by the time you pay someone to look at it, buy the parts, it will cost almost as much as a new or a used working TV.

Hello I was wondering if you had any success on your LG LED TV ? I have a 50" LG HDTV and it just happened to me.
I did call the LG hotline and because its under 1yr they are sending out a repair guy, but what ended up happening to your tv did you get it fixed?

Thanks, Irishgogirl

I bought the 65 inch LGUltra HD 4K Smart LED TV (Model #65UB9200) 3 weeks ago, and I have had this happen several times in the past week. I called LG support and they are sending out a local repair service to take a look. Tomorrow I have to call the repair service to schedule a time, hopefully they can accommodate my wife and I's work schedule. I am not happy to have this happen so soon on an expensive TV. I'll keep you posted what happens.
FYI - I bought the TV and had it installed by P.C. Richards

This has just happened on my 55" lg led. Flashes up the lg on screen. Then completely black but with audio.

Done a couple of tests and shining a touch on the screen reveals nothing so it's not the back light.

When your engineer comes round... Maybe ask what the problem was and the solve for it? Far as I can tell... It is one of the rear boards?

If anyone can shed any light on it that would be great. Looking to repair this myself.

Model 55la620v

Also to note the red led at the bottom of the tv, flashes 2-3 times.

Hey Irishgogirl! This is actually happening to me now. I also have a 50" LG TV. I purchased mine almost 2 years ago though, so it is not under warranty. Did they tell you what was wrong?

Did you find the solution? Mine does the same thing....

It's your leds. You get a flash on the screen when you power it on but then goes to black screen. You have a couple of leds that are not working behind the panel. I've replaced many of these on many tvs. It's a total breakdown to replace the strips of leds.

Would you have a link of leds to purchase?
The screen is giving me lines, static and a flash of a bit if picture, then black again. I'm really hoping if I do the right research I can fix this tv for my husband. So no motherboard, leds?
Thanks.

Jake 1441 have you gone and updated the OS. I had to do that for mine after I had a tech come out. You can do a search to show you how to update it. However, lesson learned, don't buy from the French. I have it recurring again, most likely a blown capacitor.

My 50 inch did the same thing couldn't get help from lg because it was 3 months out of warranty did some troubleshooting it was the led backlights bought some from shop jimmy for cheap and changed them myself wasn't too hard to do and tv works fine again 50 bucks for all the LEDs only needed to change one strip have the rest in case it happens again sounds like a common problem

Hi Irishgogirl,

I also have a 50' one, 3D. I'm having same issue. I got mine 2 years ago, so no warranty. Did the technician tell you anything on what had happened?
