Flyback shot by 4 year old with water pistol

Your 4 year old son shot the Sony in the flyback transformer. Smoke and sparks everywhere. Great aim!

Who says these FAQs cannot be funny?

Needless to say, unplug the set immediately. Inspect around the target area for obviously blown or damaged components. Test fuses and fusable resistors. Repair burnt solder connections and circuit board traces. Once the set is entirely dried out, power it up - preferably through a series light bulb and/or Variac until you are sure nothing else will let loose. Look, listen, and smell for any unusual behavior. If it now works, then consider yourself lucky. If not, there may be damage to transistors, ICs, or other components.

We're seeing another 'hazard' these days, people cleaning their television screens with window cleaner - no problem in the days of separate chassis but with the entire circuit board jammed under the tube on most TVs these days just a few drips and its all over. Some have just corroded the switch banks (had one recently just got into the A/V switch - when you walked around the room the set changed to A/V and back by itself!) but a few have got around the microprocessors and surface mount components and resulted in complete write-offs. I suppose the damage is the opposite of electroplating as the microprocessors have constant voltage to them. Never mind, they'll be a good source of parts for future use.
