I'v got a Magnosonic 15" with HDTV resolotion (1280 x 760) that
runs of
12 volts, I don't have the manual with me IIRC it uses less that 2
amps.

That's a top quality brand name. Where did you buy it ..... on a
trip to India? Are you changing your story now by stating this thing
has "HDTV resolution" You stated you had a flat panel HDTV. Does this
Magnosonic thing have a HDTV tuner built in? Does it have a 16:9 ratio
screen? If so where can one be purchased?
