Yes mines still dead for now. LG set up a repair for Friday. I will keep everyone updated on the problem. I get sound and the edge lighting comes on for a second but no picture, no menu, no LG symbol at power up, just black screen.

I have a 60LS5700. I am having a minor annoyance with it. When I pause a show for a period of time the speaker system switches back to the sets speaker from my external speaker system. I keep going back into the menu and switch it back to the external speaker. Anyone know if I can do anything to stop it from doing this or is it just a quirk of the set?

Your set died?

Crap. That doesn't exactly bolster my confidence. But mine is still plugging along.

Ditto that... frown.gif

Okay mines up and running again. They replaced one of the boards. As I found from the youtube video I watched it was actually a Sharp board. The repair man seemed to be surprised. The good news is he told my wife our set was one of the best pictures he has seen. He likes LG's..

I got an firmware update today, on 47LS5700, I forgot take down which version. My network connection is wired ethernet.

After upgrade is done, power off and power on again. There are some new agreement pop up need to be viewed and agreed. Then I watched your tube a a while (20 min...), then TV is dead. No picture and sound at all.

When connecting a power cable / poweron with remote, there is 1 long RED, followed by 2 short RED, then LED is dead.

Any idea ?

Hi Guys,

I have a problem with my LG LED 47LS5700 TV: BLANK SCREEN / SOUND OK

1) The sound working well
2) There is no picture but the backlight is working, because I can see the light --> Blank (black) Screen, not white
3) I replaced the T-CON Board --> Ref: 6870C-0401B / Programmed by a supplier for 47" size screen
4) I checked All Capacitors on the Power Supply Board - everything look perfect (not blowing, not leaking)), I replace a couple of them to be sure in case of..
5) I measure all FUSES on this Power Supply--> OK !
6) I measure All diodes --> OK !
7) I measure All Output voltage as printed on the Power suply Board: 24V, 3.5V... : OK !

Do you have any advice, What can I check ?

Many Thanks for your attention and Help !!

Cheers

Tao
