The cheapest, fastest, easiest, and SAFEST thing to do is to use a 120v/240v
step-up transformer.... available special order from Radio Shack or other
mail order suppliers. Make certain you get the proper VA or Watt rating.

I was recently given a Phillips 33FL1785/61R television. It is a
250volt,
NTSC model.

I realize this may sound like a crackpot idea, but could this be
converted
to run on 120v? Would swapping out the power supply do the trick?

I tried contacting Phillips and did a google search to no avail. I'd
hate to
throw this thing out if it could be salvaged.

Thanks in advance


If you know how to do safely do a diode voltage doubler, you can (and
it is a switcher type). TV sets don't care bout the line frequency.

I would somewhat disagree. With an AC-DC-AC-DC convertor input, the
filter capacitors for the rectified ac need to be larger when powering
from a 50 Hz supply.
