Question about Sharp Aquos LC-37G4U 37 in. HD-Ready LCD Television
My older television (19 inch Broksonic) had started taking a long time to come on. Now it only has a thin line across the screen. It's as if someone painted the screen black, then took there finger and ran it horizontally across the screen. It still has audio.
I'm guessing that this is a CRT based TV, not an LCD. That being said, the problem is a failure of the vertical circuit. Usually this is a small flat IC (LA7837 or similar). Try resoldering the pins if you can first. If that fails to resolve the problem, replace the IC. Please be aware that there are potentially dangerous high voltages present even when unplugged.
Keep us posted.
