I've checked on line for a schematic of this TV but was unsuccessful but I suspect it is one of two problems.
1) A fuse inside the TV was blown from a power surge caused by the storm. If you can locate it pull it out and look to see if it looks blackened (even a little) or if the wire inside is broken. This would indicate the fuse did it's job and stopped the power from burning out the whole TV. All of these fuses are available at your local electronics store or Radio Shack if you have one nearby.
2) The power supply on the TV was hit by the surge and burned out. There is no simple solution to this problem as the power supply would need to be replaced and the only way to do this is to hire a qualified TV repair service. If you happen to be good at soldering and understand electronics you could do this yourself after buying the power supply on line. I checked online and the part is about $60-70 USD.
There is a possibility that the power surge could have fried one of the circuit boards and if that's the case then you would have to weigh how much you want to pay to repair the unit after having a repair service estimate the work. I feel pretty strongly that you have one of the other two issues I listed since you didn't mention any other items in your home that were damaged at the same time. If there were more items then I would suspect the power surge would have been much more massive and likely caused considerable damage but since not then the damage would be minor leading to my previous conclusion.

How can I unlock my Sanyo TV set


Without its remote control; you can't unlock it.
If you wish to buy its original remote control, contact the authorized service centre, or authorized dealer to your device brand. They can either give you a genuine remote control to your device, or can direct you, from where can you purchase a suitable one.

But, was the cable/satellite feed protected? Lightning can come in from anywhere, not just the power line. The bad thing about the way cable and satellite installers ground things is, they ground to the same grounding system that the house does, which can backfeed the surge through the entire house - it shouldn't, but it can.

I would, however, contact the maker of the surge strip and attempt to file a damage claim. They all come with a liability warranty of some sort.

After a lightning storm, my TV will not turn on. Is there a fuse or something on the in coming power that may have blown causing it not to turn on?


Any TV subjected to a power surge will have problems. If you can remove the back cover, do so. Locate the glass fuse. In the best situations the fuse is clear and opened, and replacement will repair your TV. In worst cases the fuse may be blackened, and you will see that many components are burned and shattered. If this latter is true, only replacing the TV is your best bet. In many cases electronics may be connected to surge protectors, but lightning will over ride these devices and cause damage. I have seen this happen many times.Thanks for asking and show all hands of support!

A lightning storm will destroy a TV in many cases. I have repaired very few, with this problem. I would certainly find a new TV, if this is the case for sure. Thanks for asking!
