Hello,

My new Star Trek has a switch mode power supply bolted to the top of the
burned out linear power supply. I was considering restoring the game to
factory condition, but with your above comments, I'm not so sure I
should! Could you detail a procedure for bulletproofing this monitor? (I
had thought the 'fire' problem lay in the fan blowing on the deflection
transistors, fanning potential sparks into flame, but now I'm not so sure!)

Thanks,
