Question about Sharp Aquos LC-37G4U 37 in. HD-Ready LCD Television
You have a power supply issue and or a luminous tube (florescent ).
There also may be a LCD issue which points to a repair at the board level. A tech will be able to determine this with test where the issue is on the main board.
I hope this helps.
