My Samsung is a SyncMaster 730B. The power board is
separate from the LCD driver board, so it was possible
to completely remove the power board after discarding
the high voltage fluourscent lamps.
Recently I found out that the LED Luxeon drivers I'm using
are switching mode (and produce RF noise). One of my projects
is to build an analog LED driver.
Marc, hang on to those Dell Trinitrons! I've tried many
monitors in my 16 years as a software engineer. NECs
are by far the worst, Dell Trinitrons the most tolerable.
My foray as an ES began in 2001 after I bought a new 19"
NEC CRT for home. I was glued to that blasted thing. To make
things worse, my apartment had an ambient magnetic field of 3
mili gauss.
Getting a Turion 64 equipped laptop (Lance Armstrong model) fried
me, even 6 ft away (live strong my butt). Then the NEC LCD at work,
and cell phone finished me off.
There are some EMF ratings for cars over here:
http://www.ahappyhabitat.com/cars.htmlFor instance, the driver of a Toyota tundra gets a whopping
7 mg field, whereas a Chevy 1500 is negligible. Good information
if your in the market for a car. I also found some Cadillac
models that put off a very low magnetic field.
Eli.
