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!

I have 55LG6200. I had the same problem. Look like it happened after a firmware update. Any clues .. any body got resolved?

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.

Take the screen off hit power and watch LEDs if any don't flash its LEDs if they all flash its probably t con board had same problem with mine it was LEDs does red light on front flash 2 or 3 times shopjimmy on line has the parts for cheap 50 buck for all LEDs and 20 bucks for t con board

Hello Clifford_3,
The LED lights are all on but didn't blink when I turned it on. I replaced the TCon and the LG logo came up but then the screen blacked out again. Any suggestions? I do appreciate your tutelage.

I have the same issue with that same TV. How did you get yours fixed?

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.

Can you give me an idea of material cost, for 47" LG; to replace leds, and what physically, has to be done to replace?

So mine, flashes the Lg logo then nothing - is not the toon board. So next up for me is the power board. Trying to find one at the moment in the uk.

Hello guys,

So I have now fixed my TV. Mine flicked on showing the LG logo then off. *no dark patches on the screen - which means no dead LEDs* sound was as normal.

The fix for mine was the power board which is located in the middle of the tv. So if you have no dead LEDs it's likely the power board - PCB: EAX64905601 (eax number for my board).

Cost of a second hand tested board here in the uk was £22.

Mine is doing that exact thing. How much are new LEDs and where can I get them?
