My LG LED TV keeps going blank on the screen but the sound is unaffected. There is a faint 2 inch wide line that goes from top to bottom. It is connected to a BT vision box. Any help would be appreciated
 
Welcome.
Does it go blank and Is the line visible on other sources and on the TV's menu?
How is the BT box connected to the TV, scart or HDMI cable?, if HDMI try a different HDMI cable?
How old is your TV?...is it under warranty?
What is the TV's model number?
 
Hi
Yes the line is visible on other sources .Tried another HDMI cable no difference. The warranty has run out. Model number is 49UH850V-ZA
