You can look for the model and brand, look for it on the internet and see if you can have the schematic diagram, you're lucky if u can. Lightning will strike first the tuner side, if there is a red blink, the primary side may be okay in switching type regulator, just replacing the charred part may not solve the problem. look for shorted components on the secondary of the power section.

Baldwin EP 101 When I turn it on there is a loud roaring sound. Can not control the volume, and no keys will sound.

Even a nearby lightning strike can damage electronic equipment, and other things that can cause damage are surges, transients or voltage spikes caused by power outages. Commercial electronic equipment isn't protected against such things.

Older equipment that used thermionic valves or tubes were more resilient to such things but even they are unlikely to survive even a minor lightning strike. I once had an old tube type tv and the antenna was struck by lightning - the tv lit up the corner of the room fizzing and popping with blue sparks flying for a couple of seconds. Nobody was more surprised than me when it still worked, though it was never the same tv again...

Later equipment with semiconductors and especially integrated circuits or silicon chips are very sensitive and easily damaged and even if they do survive they will almost certainly fail at a later date. Memory type circuits are extremely easy to damage which is why they have to be foil wrapped, placed in conductive bags or packed in conductive foam until used...

Your piano will need expert attention to assess the damage but it wouldn't be surprising if repairs cost more than the insurer was willing to pay; hopefully it is insured...

Would replacing the main board fix my TV?

We can't predict what might have been happened during a lightning strike. If the TV is dead now; the main power supply regulator board [SMPS] board is fault. If so, you have to replace it first. then only we can get information about the condition of the main board. If the TV was connected to external Ariel or cable; before the lightning stroke; the possibility to damage to the main board too is there upto 80%.
In fact, if both of this boards are damaged, it might cost around 2/3rd of the total cost of a new TV.
The decision left to you. Do whatever you want.

Which circuit board on my Smart TV might be broken after a possible lightning strike. There are two main ones. The power is getting to the unit, but I can't get the menus, connections etc to work.

Nobody can predict, what might have been happened to your TV after a lightning strike. Do you thing anybody can? Is any technician have a super-natural power to predict the faults that might have been happened due to lightning (More than 10 Million volts to start on stroke) ? Can you?
Sorry.
Contact the authorized service center. OK?

Plasma Panasonic TV stopped working

Lightning-damaged electronics are a gamble to repair. Sometimes the problem is a single component, but more often multiple components are damaged, and even if you get it working, something else may die shortly thereafter. If you are lucky, only one board was damaged. My recommendation, if you have homeowner's or renter's insurance, is to put in a claim for the TV and get it replaced.

Having put forth that caveat, the blinking red LED hints that you may have enough left of the set for it to be repairable, especially given that much of a plasma set is already built to cope with high voltages. Try downloading a service manual and following the troubleshooting procedure. Here's the link (it's a Hungarian site, but there's enough English available to find things):

Will a nearby lightning strike cause a power board failure?

It could happen yes it would depend where the strike entered the TV. Not all lighting strikes hit on the electrical lines, on a TV they can come through the cable, as well as a antenna if you have one hooked up.

Toshiba 37AV500U damaged thru HDMI input.

The lightning stroke has been effected to the main digital board to your TV. It will be best to replace the main digital board as card basis, rather than trying to repair it. Before replacing the board, a through checkup should be done. Contact any expereienced service technician for help, as this work is a very skilled one. No body can predict about the damages to a lightning stroke, as there will be trillions of voltage present for every stroke, and even a slightest voltage can damage so many components in a TV like equipment, as it is designed to work for 110 or 220VAC.

My 32" LG TV has no power. It was plugged in when we had a close lightning strike. It was not turned on. Afterword, the power light blinked red and I was able to get the tv on. However, after I shut...

This sounds like the power supply has failed. It is also possible that there are other faults in the set that occured at the same time.
