Bad storm, lightening strike outside then TV went off and will not come back on.

Lightning strike? Scrap it and buy new tv.

Is your TV plugged into a surge protector? If not it very well may have gotten a power surge during the lightening storm that fried components in the TV.
Or is the TV connected to a cable box? It could be that the cable box took the hit if it's not plugged into a surge protector.
Or a possibility of both.

HAVE YOU CHECKED PLUG AND INTERNAL FUSES

take the back off and find the fuses,pull them and have them tested,replace with theSAME FUSE TYPE there is a short blow and long blow.get them at radio shack

100 to 1 odds the capacitor got zapped when the power went off.Top of the capacitor where the wires connect should be flat. A lightening strike will cause it to be puffed up.

Look to see if the rear video/audio inputs work (DVD etc) and if they do the damage is at the tuner in the set (nearby lightening can discharge into the cable or wires for signal.)

If using a box (cable or satellite) it may have took the hit.

A good idea if lightening storm is to not only unplug set (static discharge can come in via the power cord also) but disconnect signal source from set.

I have in extreme cases seen a nearby strike get in via the power lines and destroy almost every appliance plugged in even if not on.

Your surge protector did not function properly, contact the manufacturer of the power strip.

obtain the latest time machine , go back to an hour or so before the lightning strike and install a quality surge protector .

Lightening may have caused a surge on your power lines to the house and to the outlet the TV was on.
Do other things work on that outlet? If not you tripped a power breaker.If they do work check this.
Unplug the TV for 2 min or more and plug back in.
Try bypassing your surge protector you had it plugged into. It could have died when the lightening struck.
(no surge protector?) Bet you'll buy one for your next TV.
Look for 3000 joules and up rating for a surge protector and insure it has protection for a cable/antenna input too.
If this doesn't work the TV may be fried or internal fuse blown.
Time to take it to a repair shop or depending on it's age (5 years+) it may be time to buy a new TV and surge protector.
Near Lightening strikes can effect appliances from several inputs that could be affected from outside like Power, Cable, Antennas, Phone Lines that come into your house.

it is possible to fix it. There may be some burnt fuses and a couple of resistors. But it can be fixed in my opinion.
