I'm having a fault with my Sharp LC70le650x 70 inch led TV.
It's approx 2 years old.
The screen does not show any picture but I can see that the backlight is still on. I've shined a torch on the screen too and can't see a picture.
There is still audio when I plug a DVD player in to the av ports.
The problem had occurred before and a tech came out and reset the TV, I believe using the input / chanel buttons, and the problem went away for a couple of weeks.
I've since tried doing this and managed to get the menu to pop up for a second but it quickly disappeared. Every other time it's turned on, whilst you can see there's light, no picture is present?
Your help would be greatly appreciated
