What's the likelihood of my TV being able to be fixed after a lightning strike killed all electronics on one wall?

A modern tv is as much computer as tv and isn't electronically robust having much delicate circuitry that is vulnerable to surges, spikes or transients.

A direct lightning strike isn't necessary to cause damage and lightning activity in the area is all that is necessary. A surge protector could provide some protection but in reality disconnecting the tv from the mains and the antenna is the best protection.
In the early days of radio when circuits were more robust, an external antenna and a good ground was often necessary for good signal reception, there would be a knife switch provided to disconnect the antenna and ground it whenever there was thunder around - a worthwhile precaution that unfortunately isn't practical today.

A tv that has failed during an electrical storm might be economically repairable or might not - only the repair guy could tell you this. My limited experience with this tells me although such a tv can be fixed it never seems to achieve the same quality.

Ask friend if broken when given to you. If not I would suspect the power supply is fubar..

needs circuit testing doubt you would actualy be able to see any damage to circuit boards doesn't take much of a power surge to knock one out tv engineer needed

The control board(s) are fried. Cost of parts, assuming they're even available, is likely to be very high. Not a DIY project.

Call your home insurance company. You should have at least some protection for lightning strikes - but there could be disclaimers regarding electronics unless you purchased a rider.

Your power outage may have been caused by a nearby lightning strike, or any number of
1000 different reasons that cause power surges, brown-outs, voltage spikes, inductive loading,
and/or utility pole breaker trips and resets (this accounts for your power loss (a pole breaker trip),
followed by restoration of power (the pole breaker automatically reset) - even plain old high electrical demand causing an overload due to air conditioning demands caused by hot weather.
When the pole breaker reset, your TV caught a power surge.
Whenever a power outage occurs, quickly power off (or better, unplug) any/all computers, TVs,
etc. that are not protected by surge-protection.
As an electrician, when someone loses an item of electronics concommitant to an electrical
anomaly, its almost
always traceable to a nearby lightning strike (or the power company provided equivalent), accompanied by inadequate surge protection for
the VCR/TV/Computer/Stereo/uninsured valuable electronic item/XBOX 360/Nintendo Wii.
Surge protection can
be provided by the consumer at the power strip (a good one with builtin MOV protection and a
warranty costs $20, whereas a zero-protection 4-outlet or 6-outlet power strip will cost $4-$5).
Your electrician can provide whole-house surge protection where a whole-house MOV-based (metal oxide varistor) surge protector, or per-circuit protection can be installed with
a GFCI breaker (or better, an AFCI breaker) can be installed.
GFCI = ground fault circuit interruptor
AFCI = Arc fault circuit interruptor
Lightning protection is especially important in Florida, which is the "lightning capital of the world."
I've never found a good solution to lightning-fried electronics (random power supply components are destroyed and/or fuse blown), other than renters insurance or homeowners insurance.

Your only real hope for an economical fix is to look for a blown fuse, and replace it.

If desperate to attempt a fix on your own, you could try replacing the entire TV power supply as a module, but even this provides
no guarantee of a fix - lightning damage can extend beyond the power supply.
When traveling, I will always unplug everything before I leave (except the security system),
and also turn off the breakers to unneeded house circuits (which kills the wall switches that
control interior lighting - forcing a burglar to use their flashlight instead of interior lighting)
which is the least convenient lightning protection, but highly effective, and cheap (free).

As an electrician, when someone loses more than 1 item of electronics in a day, its almost
always traceable to a nearby lightning strike, accompanied by inadequate surge protection for
the VCR/TV/Computer/Stereo/uninsured valuable electronic item/XBOX 360. Surge protection can
be provided by the consumer at the power strip (a good one with builtin protection and a
warranty costs $20, whereas a zero-protection 4-outlet or 6-outlet power strip will cost $4-$5).

the breaker box, where a GFCI breaker (or better, an AFCI breaker) can be installed.

The converter box may be replaced by DirecTV, you'd have to contact their customer
service at http://www.directv.com/DTVAPP/content/customerservice

Hi.
Yeah, lightning can wipe out electronics really easy.
I would file a claim with your homeowner's insurance policy.
Surely they have these kinds of things in your policy.
As far as getting it fixed, first you will need to get estimates from 3 different companies for your insurance company.
I would take it to BestBuy, Fry's, Staple's, or CompUSA.
All these places have service centers, and I am sure that they have all seen lightning strike damage and insurance quotes.

I hope that you get it going again, or that you get an approved claim, as it was an act of God, not an intentional act which affected your tv.

Good luck to you, and have a good day.

The warranty does not cover lightning, check if your insurance covers it.
A lightning strike on such panel ( HDMI ) is very difficult to repair and if not impossible.The HDMI connector is hooked to the ground of the TV set so everything could be damaged.
My advice is not to repair.

I have the same tv, but the problem I have is the picture is shifted to the right and can not correct it. At 1700, its probably not worth fixing because to expensive to repair, they dont make it anymore
