Have you tried to reset your TV to factory settings, and to call LG support ? an official patch shouldn't break the TV this should be covered...
Your description remind me a not compatible screen resolution or frequency...

I've tried everything.

Sometimes the image comes back, but only the right side of the screen.

Hello,
I was doing Webos 05.30.11 update on my Nanocell SM8100PVA when I saw your messages, I stopped it at 97%...
Have you been able to solve your problems ?
 

I don't know what is wrong with my tv.

The image came back for a day, then on day 2 the left side of the screen started dimming every few seconds, then full bright again.. but now with scan lines.

Now it's completely dead again

My TV too.
After the update my screen remains black. Back light is on and the TV is working. I can start Netflix, play content, hear it, adjust volume etc, but not matter what I do, I cannot get it to display a picture at all.

I have tried soft resetting by unplugging it for 30 minutes, holding the power button for 60 seconds etc. Nothing works.

It's this TV. 
I can't even download a firmware to attempt a manual update.

How does one fix this?
