Default Removing smoking smell out of electronics?

I just a got great deal on a Samsung 32" HDTV. The only issue is the
smoke smell. Is there a way I can
get it off and out of my new HDTV without ruining the TV? Thank you.

Note that the original question sorta hinted that this is a NEW
Samsung TV. "Great Deal" around Christmas time usually means he
bought it on sale somewhere. Unless someone at the factory smokes, I
doubt if the TV had time to accumulate enough tar and crud to stink.

electronics used around smokers develop a smelly grunge film that needs to
be WASHED OFF,and then dried for several days,preferably in a drying oven.


Yep. My method is to use common 90% alcohol and give it a bath. If
immersion is possible, I do it. Hitting it with a hot water spray, to
wash off the ionic contaminants, water soluble flux residue, and
general accumulate crud, is not beneath my dignity. The trick is to
immediately blow dry the boards with an air compressor (with a dryer
filter attached). If there's something involved that's porous (wood
or press board cabinetry) or can't be washed (paper speaker cones),
then I have to let it air dry for a few days. Otherwise, the smell is
usually gone with the blow dry.

I did a lot of that while I was at Tektronix.
It sometimes was so thick that you could see the brownish yellow gunk
running off as you rinsed the unit.


Yep. To keep my office/shop clean, I won't let anything inside until
the dust has been blown out and all the crud removed. I clean
everything, even if I later decide that it's not worth repairing.

that gunk also attracts and hold other dirt and grime.it's NASTY.


Yep. For the ultimate mess, I have to deal with a machine shop that
uses various plastic case laptops and PC's near the machines. Hot
chips melt and imbed themselves in the plastic parts. Oil, dust, and
dirt adds to the mess. I usually have to scrape the case for chips
with a putty knife before I can safely move it. I wanted to baptize
the PC in the vapor degreaser, but the owner wouldn't let me.

Another fun mess are kids laptops that are literally wallpapered with
stickers, pogs, and stick-on skins. All the sticky back stuff can be
removed with some solvent or other, but there's no solvent that will
reliably remove all the different types of sticky glue.
