There's usually several layers of power supply/protection between CRT and power line in a solid state set. A surge will usually take out the bridge rectifier and parts in the power supply of solid state sets. If lightning hits the antenna the tuner balun will fry and possibly other parts in the tuner.
If you're worried about the CRT you could unplug it and hook a 6V lantern battery across the heater pins. If the heater lights it's probably all good.
