TV Will Not Turn On

We had a thunderstorm that seems to have knocked out several electronic items, including our TV. Right now, it won't do anything. The three indicator lights are all illuminated--not blinking, but constantly on. I cannot find anything that says what this means--all references that I am finding refer to these three lights blinking. Does anyone have any ideas where to begin? Thank you!

You begin with a call to your homeowner/renter's insurance company. Typically, lightening strikes are covered.

As for repair, lightening strikes is the ultimate stress to a device. I don't repair lightening strikes. I don't even save the PCB boards of lightening strikes for spare parts, since I have no idea what kind of stress that component has taken. Even if it works at first, how long and will it work predictably.

If your insurance won't cover, and you want to attempt a repair, you will need to open up the TV and systematically diagnose the TV. Start with the power supply, and move forward. You will want an oscilloscope if you don't already have one, since you'll need to know the quality of power coming out of the supply. Also, be ready for a lot of soldering.
