Question

LG LD790 TV ** no HDMI signal but worked before

Jun 12, 2013 6:18AM PDT

I have a LG LD790 TV connected to a DVD recorder via HDMI.

It was working fine (for over a year) but now displays no signal through the HDMI inputs.

I have tried different leads and have connected up another HDMI dvd player with different leads as well.

The inputs ARE displayed on screen (like it is recognising them) eg HDMI 1 HDMI 3 but when it tries to find the device it then displays no signal.

I have looked to see if simplelink was turned on or off by accident but it makes no difference either way (on or off).

I have tried a factory reset twice, so any suggestions please.

Is it a setting or a fault ?

same problem w/ LG LD550

Same here. All of the HDMI ports on my LD550 suddenly stopped working 3 days ago. All other inputs work fine. HDMI inputs display when a device is connected but when you try to use the device it returns a no signal message. Tried replacing the HDMI cables and performing a factory reset but to no avail. LG wants $200-$300 to repair. The TV is about 3 years old.

same HDMI problem on my LG 56" TV

started today. HDMI connecting from TV to DVD or Cable-Box gives NO SIGNAL on TV screen. Using AV 3-wire cable works fine.
Did you fix this problem, help if you did. Thanks.

Nope. I underestimated LG's repair cost, which I think would end up being more like $400. My understanding is that the problem can be fixed by replacing the main board. The part itself costs about $200. Low on cash so I'm now using component cables for my cable box and dvd. A/V cables work fine but component cables can transmit HD.
