You can try looking at the MAIN AC fuse first in the power supply module, since most TV will have surge protection devices, MOVs (Metal Oxide Varistor) same as use in your surge protector outlet strip, they are installed after the main fuse, and they will conduct if the surge is large enough and will cause the main fuse to blow that way the power cannot come through again if the second surge comes along.
Look for fuse which is usually labeled with F1.
New fuse will only cost $1, if the new fuse blown right away then you only lost $1, then get the new power supply.

If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

My Magnavox was hit when the house was struck by lightning how do I fix it?


You don't, you throw it away and claim on your household insurance. A 25,000 volt power surge will have burnt out every electrical component.

Our electricity went out for a few minutes, and since then the TV will not turn on. The green light is flashing. We tried resetting it by pushing a pen point into the reset hole, but it does nothing. ...


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).

Tv struck by lightning


You wont be able to fix the TV your self as the power circuit board may have blown - consult a qualified repair man. Buying a surge protector for your expensive electronic goods is highly recommended.

Lightning


Lightning damage could be all or nothing, It's very hard to tell without checks all around the boards. I think your best bet is to check with homeowners and see if they will pay for lightning damage and if they say take it to a tech to fix and they will pay, go that way. But If you want to DIY, then the best thing is to call PTS 18008447871 and price a Deflection module. This is more than likely the area, but still not 100% sure. But it has the HV area on it. This will still be around 200-300 and it most likely will fix the problem. Hope this helps!

TV was struck by lightning


If it was struck by lightning, the surge would completely fry the insides of your TV. Your TV probably won't work anymore and you may have to consider replacing it. Some TVs have accident warranties so something like this could be protected, but if not, you will have to purchase a new one.
