Facing TV Problems? Ask a TV Technician.
Hi, I'm Nathan.Sorry to hear that you're having trouble, but I'll do my best to help you. Please give me a few moments to review your details here.
Could you give me the full model number of the tv?
Are the lines vertical or horizontal?
Could you look on the back of the tv for a model number if possible?Sending me a photo of the lies would be helpful as well.
Also, if you bring up the LG menu screens, do those lines show over top of the menu, or behind the menu?
