Question about Sharp Aquos LC-42D62U 42 in. LCD HDTV
I was watching the TV but then some coloured lines came up and then there was no picture but sound in the background (of the channel). Now when I start it up I get some coloured lines then it goes black, but still with the sound.
What can I do??
Turn on the set and get a strong light and bring it up to the screen. Do you see a faint image on the screen? If you do, then your backlight has failed. It may be one of the many lamps, or the inverter circuit or the power supply for the lamps.
The colored lines usually indicate a broken screen from an impact...unlikely unless someone hit the screen just before the picture went out.
