I have 'wavy horizontal lines' on my TV Screen. I disconnected all other appliances and put on the TV only, but the problem persists. I plugged in the TV in several other sockets at home but the lines still appear on the screen.


Thanks for your help.

My broadband supplier provides me a Decoder which is connected to my TV through cable. The Decoder itself is connected to my broadband modem through cable.

My TV brand is Maxsound (Cannot find the model)..

I switched on the tv only (without antenna or decoder or dvd connected etc) and the horizontal lines still appear.

Around two months ago, I installed a new broadband service. But two weeks later, the horizontal lines began to appear. Yesterday, I switched off all electrical appliances one by one to find the source but no results.

Also, my modem is found just behind my tv, with only a wall seperating the two objects.


I switched off the modem, but the lines still appear on the TV screen. Could the modem be responsible for the damage to the TV?

Thanks for your valuable help..

I don't know and I can't found this brand!

If you knock on the TV can you see those lines moved or disappear?

Try your TV in a other room and see if the problem still there!

Is this TV has a video input then if the problem remain or you use only coaxial cable?
