My 32 flat screen tv quit working after a thunderstorm. It is a 2006 Symphonic 32' lcd. I have renters ins. But at $250 deductable is it worth repairing or should I just buy a new one?


The tv is repairable but usually the damage from storms is extensive and the bill will be stiff. Get the $250 and just buy a new tv. Next time when a storm comes unplug all electronic devices from all cables, or it will happen again.

My area had a thunderstorm and our power went out now my emerson tv won't turn on. Can you help me.


Some times electrical storms contain EMP's - electro-mechanical pulses- which affect the TV permanently.

Take it to a TV technician or junk it and buy a new one.
