Hi there,

I'm new to the forums, as I'm sure many of us are once we encounter our first problem. Wink

LG 55LM7600

I've had this television for 14 months, and today was my first SUDDEN encounter with any problem since day one. After the television had been idle for about 10/15 minutes, I came back to the screen all black with vertical white lines across the screen. The white lines seem to fill only the section of the screen where an image is being displayed. Even if the image is a small television cursor, the line will still go from top to bottom. I've attached 2 photos to give you an idea of what I see.


I do have children, and there's a chance it was jostled/bumped while I was away from the television. I confronted them and they said they didn't go near it, however my 2 year old, there's no knowing for sure. Is it possible that an LED cable came disconnected inside or something?

Anyway, any help is appreciated!!

Warm regards,

It sure looks like a bad panel.

My 55LM7600 has the same problem, i'm not sure but my 17 month old baby was spilling water close to the tv set a few days before it failed for the first time.

At the beginning there were a few lines missing,,, a few hours of use later the vertical lines appeared.

I found the main board at ebay.. will try to fix it.. I will post my findings.
