If you're referring to a replacement battery, please google your model and use the word battery. Otherwise, lightning tends to short out all kinds of stuff.

TV out after lightning strike. TV led light comes on for 5-10 seconds then shuts off. Phillips 46pfl3505d/f7. Can this be fixed?

Sure it can be fixed. Most likely a problem with the power supply being zapped by the lightning.

Check to see what the price of a new PS is and is cost effective given the age of the set.

Power surges, such as those caused during lightning storms, can often cause power supplies in electronics to fail. Sometimes, if you're lucky, the manufacturer will have placed a protection fuse in the power supply which can be replaced after a surge. If there is no such fuse, the power supply typically will need to be replaced for the equipment to regain function.

It is VERY IMPORTANT to use SURGE PROTECTORS on all electronics, especially if you live in an area where thunderstorms are commonplace. This will protect your electronics from most (not all) surges that would otherwise zap them into failure.

Lightning strike nearby, no power from the card what so ever

The most likely explanation is the high voltage from the lightning has probably zapped the sensitive electronics. It is however worth checking all the fuses are OK
I hope I have been of help but please do not hesitate to ask if you have any further questions.

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.

sounds like maybe the power supply got zapped threw a surge. you may want to get a technician out there to confirm. not too expensive to fix.
