Re: LG 70LB7100 no backlight after 2-5 min
Gotcha. I'll probably go ahead and take the TV apart first to verify before ordering. I got the TV for free from a buddy, so spending a $100 or so to possibly repair is a risk i'm willing to take....

Thanks much for your help. Do you happen to know how many rows this TV takes? I haven't taken it all the way apart yet....Leave a comment:

Re: LG 70LB7100 no backlight after 2-5 min
can you guys recommend a place where I can get replacements? is that a super difficult fix? I've heard it can be tedious handling the screen itself to gain access to the leds...Leave a comment:

The only thing I can find on adjusting brightness on this model is just adjusting the picture to energy saving mode, which I did and the brightness dimmed way down. i did that after disconnecting those two cables I mentioned earlier. after disconnecting the cables and reconnecting the leds stayed on for long enough for me to adjust that setting, and that's when it stayed on for like 30 minutes (which is WAYYYY longer than it had stayed on before)...Leave a comment:

yea, it went out after like 30 minutes. no warmth felt at all, all sides seem cooler than room temperature. i shined a flashlight on the screen while a movie was playing and i COULD see the picture in the backround.
Must be the backlight then, eh?...Leave a comment:

Re: LG 70LB7100 no backlight after 2-5 min
well, i unplugged the ribbon cables going from the tcon to what i believe is called the main board, and the screen has now been on for like 10 minutes...which is WAY longer than ever before. it used to go out in like 5 - 10 seconds maximum. could it be there was a bad connection? gonna let it sit for a while with the screen on and see. i was able to then change the display setting to maximum power save, which dimmed the screen considerably, so not sure if that is helping or not......Leave a comment:

So unfortunately I don't have the remote for this TV, and it doesn't appear that the little joystick button on the bottom of the TV will adjust brightness.....I'll have to look around for a remote for this model TV so I can try the brightness adjustment. With my TV, it always blacks out at the same time, about 30 seconds without fail, it never changes. It's almost like it might be the TCON board, since when the monitor is lit there is no flickering or dead spots, it looks perfect, then 30 seconds or so, it blacks.Leave a comment:

Re: LG 70LB7100 no backlight after 2-5 min
Anyone figure anything out with this? I was given this TV for free from a guy and it's doing this exact same thing - backlight stays on for about 45 seconds, then shuts off. Sound continues to work and everything. Replaced the main board, and that didn't fix anything. I'm considering replacing all LED's, but was hoping someone would have confirmation that that's the issue before spending the time and moneyLeave a comment:
