LG 47LM7600-UA displaying horizontal lines

by draneb / February 27, 2015 8:36 AM PST

Hello everyone,

I have an LG 47LM7600-UA. 47 inch 3D tv. I bought it 2 1/2 years ago with a 2 year warranty and it is just now having problems (horizontal lines) 6 months after the extended warranty expired, go figure.

There are horizontal lines that are present no matter what source I am using. They go all the way across and are spaced out the same distance vertically.

I was hoping someone could tell me by looking at the picture in the link provided if this is something I could fix by changing out a board (like power board, main board, t con board) or if it is something like a panel problem (which I've read isn't worth fixing because of the cost involved).

This is a closeup of the Netflix icon in Roku. They appear most obvious with the white background.


Does anyone know what the problem may be? As long as it's not the panel I would like to get it fixed. Thank you for your time,

Just to repeat.

Looks like what I found on the web so far. It doesn't mean it's a board, noted cable or panel. A tech has to dive in and see.

Hi Draneb,
You should exhaust all your options and you may want to contact the LG Customer Interactive Center (800) 243-0000 to ask if they have any flat fees or what it might cost to repair the issue. Ask them what the diagnostic fee would be and if it's non-refundable or not. You can also visit the LG website www.lg.com/us/support and get a list of local Service Providers and contact them to see what they would charge and again, ask the above questions. That would give you a better idea of whether you need to get it repaired or if you have the aptitude to repair it yourself.^IFV

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
