How do I repair an LCD TV that was struck by lightning??

I have an Insignia 50 LCD TV NA-50L240A13 that won't power up or illuminate the standby light after it was struck by lightning tonight. After tearing it apart, there are no visible burn marks on the power board or main board. Also, the main fuse has continuity. I'm stumped and YouTube has only made me a mediocre TV repairman...
Any advice TB? Thanks!! :cheer:

No telling where or what all was fried.

Next time use a surge protecting power strip. Most provide warranty on your electronics if a surge hits them while using the surge protector.

I had one, didn't even trip it. Guess I should have invested in a better surge protector...

What brand/model? Like I said, most cover that damage if they don't work.

From the looks of it, it's probably a Dollar General brand. Circa 1990....

I've dug into it as far as I know. I have tested the cord and I am getting power to the power board.
Everything I see points to the power board, just not certain that's the problem due to my lack of experience with television repairs. I've replaced capacitors to repair a TV and stuff like that, but I'm not real confident with my diagnosis of this. Could the actual screen be shot from a power surge?

Make sure you have 120VAC to the power board(the tan board in the middle). If you do, that will rule out cord and fuses. Then just replace the power board. It only $53 at Power Board
Lightening could have damaged other components but for $53 it's not a bad idea to replace the PB first.

Your coax should also have a grounded connection outside, to absorb a direct hit and irect it away from everything.

Quiz: How do you verify at an outlet that the ground is intact?
Posted on 9/7/14 at 11:13 pm to Spock's Eyebrow
A. Look at where the coax enters the home. There should be a barrel type connector with a grounding wire connected to a grounding block onnected to your electrical service or to a grounding rod inserted into the ground.
B. Take a standard digital multi meter, set to 2K ohm scale and then touch one end to a good known ground and the other end to the outer part of a coax connector. The meter should read near 0 ohm. If its not grounded it will read open.
C. Call your service provider and tell them you want it tested. They'll send someone out.

Check.

Would it be equivalent to use a continuity tester between the connector and (say) the ground of an electric outlet?

That seems perfectly reasonable.

Checked that, it is getting power to the board.

That's what I was thinking also, thanks

Spinoff question, do they make "small" surge protectors that can be hidden behind a mounted tv outside? (or anywhere). All I've ever seen were the big long ones with several outlets on it.
