I was watching tv and the screen went blank. It


You would have to try an INIT and see if it causes the tv to be operational again. It is something that you have to be walked through step by step by step and can erase the memory of the tv if done improperly. Call Sharp tomorrow morning at 9AM CST and someone can walk you through one. Call 800-237-5277 or if you have an aquos advantage model call 87-332-7867

While watching the tv, there was a sudden loud, sharp pop, sounding like a gun shot, and the picture went blank


Sounds like either something went pop on the main pcb or in the power supply. Will need a repairman to take a look. & Just a caution if you're feeling adventurous, don't do it yourself unless you know what you're doing!!

Hisense 42inch lcd tv


It sounds like it's the inverter panel which lites the lcd back light.
If it's under warranty, try to replace it, or take it in for svc.
