Red Power Light Comes On, but nothing else.

Possible lightning hit. Automatic shutoff after 15 mins. still works. TV will not power up. Is there a reset anywhere? EXTREME sentimental value to TV. Want it fixed if at all possible.

Which circuit board on my Smart TV might be broken after a possible lightning strike. There are two main ones. The power is getting to the unit, but I can't get the menus, connections etc to work.

Nobody can predict, what might have been happened to your TV after a lightning strike. Do you thing anybody can? Is any technician have a super-natural power to predict the faults that might have been happened due to lightning (More than 10 Million volts to start on stroke) ? Can you?
Contact the authorized service center. OK?

Right now I believe the TV is in " Protection Mode ".
Try leaving the TV unplugged for 30 minutes, that way the TV can reset itself.
If that doesn't work, most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a backlight Inverter Board.
But, I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20. And most cases the new part cost less than $15.

I hope I shed some light on the subject for you.

1. Hold [menu] and [vol-] button on the side of the TV
2. while holding these, press the [power] button on the side of TV (NOT remote)
3. blue light comes ON and stays ON
4. wait 10 seconds then let go of [menu] and [vol-]
5. wait another 30 seconds and some type of picture should appear

I think this is right. I got it from the JVC call centers guys so sorry if I missed or messed up a step.

Hitachi 57TWX20B powers on ( but no picture or sound)

f you had multiple power outages, i would contact the power company or/and insurance company and it should be covered under that, but sounds like power supply problem if you had power surges
if lighting cause it then it could be anything.

Lightning strike

Lightning hits do some nasty damage to electronics.
Alot of times that type of repair is part of an insurance claim. The insurance company requires estimates and will repair them up to the cost of replacement.

If you arent dealing with an insurance claim on this I'd still recommend a professional estimate.
Lightning damage sometimes is confined to the power supply and once repaired could be fine bit in my experience most items that take a nasty hit are a write off.
