Lighting hit it no power at all - Vizio Televison & Video

Most likely the TV has a power supply related problem. It maybe something simple like a blown fuse inside the TV. Or,.It's possible that it maybe a bad capacitor or transformer on the power supply board But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptom.

You have a few choices:
1. You can try leaving the TV unplugged for 30 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route. ( Just don't tell them lighting hit it ) :)
3. 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.
4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.

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