Typically this is because the horizontal output transistor is shorted or there is a major problem with the power supply. If you have no experience with TV repair, I would bring this in for a repair estimate.

The fuse probably is internal. It may be necessary to remove your OTR microwave to get access inside.

During a thunder storm our polaroid tv went out..we have changed the fuse but it still isn't working..any other suggestions?


Call your homeowners' insurance agent. Seriously, if the set is worth more than your insurance deductible, you will want an expert evaluation on whether the set can be profitably repaired so you can make a claim if necessary.

Was the first fuse blown? Did the second fuse blow? If the answer to both questions is yes, then you have a fried power supply switching transistor - at a minimum. You might even see cracked or burned parts on the board that has the fuse on it (look at the parts on or near the finned metal radiators). Lightning typically damages a number of parts. You may find it cheaper to replace the entire power supply board, and hope the rest of the set isn't damaged.

If both fuses are good, that could be worse news, because that implies lightning got in through the antenna/cable input and zapped the main circuit board. This is the second-most expensive part of the set after the LCD panel.

A suggestion for "next time": if a TV set blows a fuse, get the problem fixed first before risking a new fuse on it. It's rare that a power surge blows the fuse without also breaking something else. The fuse is intended to minimize damage and prevent fire in case something in the TV shorts out or the surge protection components are unable to handle a high energy pulse on the power line. It's not guaranteed to protect the set from damage.

No power


unplug the unit for 24 hours and try it again. if the unit doesnt come on at all, even after that, then the internal fuse is blown, or a power spike / surge has friend part of the internal power supply. you'll have the go through the warranty process of the manufacturer, or find a local tv repair shop.

Tv keeps blowing fuses when its plugged in...


There should not be any reason for the new TV to blow a 15 amps fuse in the house.
The TV has an internal short circuit even if it is new, I would suggest to return it and get another one.
Good Luck.
