Sounds like a power surge likely followed the outage- or maybe you were actually hit by lightning- and since this set did not have a built-in kill-switch (circuit breaker) it could have very well caused some significant damage. Check the internal fuses, if they are blown, chances are, so is the rest of the set. For the cost of repairing something as over-reaching as this, I'd be looking for something new (And be sure to buy a quality surge protector, so this does not occur again!)

Hope this helps in some small way!

You may have fried one of your control boards in your TV. Sometimes these can be easy to fix. I recommend you take your unit to a repair shop and get a quote to repair it. Be sure to get a quote and don't just tell them to repair it. It may be cheaper to buy a new TV! Sometimes they will charge you just to troubleshoot your TV but that should be expected.

An electrical pulse from the thunderstorm has affected your TV. (Was it on a surge protector?)

There is a small possibility that it will come back.

Unplug the television and let it sit for an hour or more and then re-plug it.

If you need to get a new TV, also get a good surge protector such as Panamax.

TV won't turn on
The set is in protective shutdown because a problem was detected. The 5 blink code indicates that the problem circuit. In this case it is the blanking circuit. Were there any indications of problems prior to the storm? If not, I'll need to lok up this one for the specifics. Do you intend to repair this yourself?

Let me know and I'll provide the details.
Thanks,
Dan

Thank you!!!! Our power was off due to new transformers being installed in the area and we had no clue how to fix this. I called around and no one seemed to know the answer (not even Samsung, who only wanted to tell me my TWO year old tv was out of warranty),so I tried this and it worked perfectly!!! You saved me a bundle! Thanks!
