[TechAssist] Re: Toshiba TP50F61, EXT speaker damage

Jeff,

The polarity will not affect the TV; however, the impedance of the
speakers will.  If they connected multiple speakers or had wiring
problems that may have shorted the output line(s), or had low impedance
speakers driven at high volume, the audio output IC may have taken a
"smoke break."  That could send it into shutdown or take out a secondary
supply voltage.

Hope they don't think this is an "in warranty" repair.  Ignorance and
stupidity is chargeable!
