Power boards on plasma tv s can shock you.

Plasmas are probably the riskier board, owing to the higher voltages required for the setup. LED and LCD panels should be less problematic, unless the caps are for the starter (or whatever) on the actual lamp unit.



Shorting electronics is dicey business. One thing I have read that works for microwaves needing a quick d/c is to plug it in and drop it in a drum of water. I am certain I would be summarily removed from my job if I was found "dipping" larger appliances with a live charge so I have not tried it. That just feels like something not OSHA-approved. But for smaller boards, I suppose you could connect the power from the supply board to a power strip and just pour water over it. That sounds a little uncertain, though.

Also, as an aside, I had a spark on a defib unit but it was the lithium battery pack. I left it alone for a month to d/c the capacitor but those batteries were still packing heat. Are there permanently-mounted lithiums on TV boards? I don't see many of those so I am unfamiliar. They could be the culprit, too, though with all the cap problems flatscreen TV's have had in the last decade-and-a-half, I'd expect them to be the most likely spot for a spark.
