tv screen cleaning question
Albee Kuminova
XBR maybe close to 20 years old. Another is a 12 year old Sony XBR
squared. 3rd is a 13" stereo Toshiba tv with built in DVD. Best Buy and
Circuit City say Monster Cable tv screen cleaning kit for 20 bucks is
only way to go. In the past we've used windex with ammonia sprayed on
paper towel. Toshiba says use Windex without ammonia. I can't get
through to Sony.
It's very confusing. What IS a good, safe way to clean a dusty tv
screen?

to use on precision coated optics if you don't do it every day. Unless
there's a delicate anti-reflective coating, you have ABSOLUTELY nothing to
worry about. If there's an anti-reflective coating, you can still use
Windex as long as you don't do it too often. If you need to clean a
delicately coated piece of glass every day or two, half Windex and half
distilled water is a good cleaner.

cleaning cloth and then wipe the face of the tubes. Have the sets turned off
to avoid any possiblity of static shock from the set. Generally the material
referred to will do a nice job on also cleaning the cabinets.

off. If it is grease, and cigarette smoke stain, use water with a about 20%
isoprophal alcohol mixed in. You don't want anything too strong, that can
damage the coating on the CRT glass.

in the thread made at this newsgroup question.
I must point out that the reason you do not spray the screen is because,
most TV's today have electronics under the picture tube like customer
controls, so the spay will drip down and cause the components to rust and
"partly short out" what is called in the trade as a "gone leaky" This
would cause a lot of problems in the months to come when parts will need to
be replaced.

True, but if you're not going to do it every day, there's nothing wrong with
Windex. I've cleaned lots of optical equipment with Windex (carefully).
The main thing is to get it off again, or follow up with distilled water (to
ensure it dries clean) or sufficiently pure alcohol.

Windex on a paper towell works great, anybody trying to charge you 20 bucks
for a cleaning kit is ripping you off.

Do you mean deoxyribonucleic acid, digital network architecture, or
denatured alcohol?
I normally use isopropyl alcohol (electronic grade -- it dries clean) at
work. At home I use Windex or diluted Windex.

certainly should not be used on a RPTV screen.

in the spray bottle is denatured [rubbing] alcohol, very similar to the
grocery and drugstore materials readily available. Kit comes with the nice
red spray bottle already filled, the corduroy type cloths, and the wooden or
plastic applicator over which the cloths are stretched. Instructions
included was to spray a liberal amount on the cloth and wipe the fresnal
screen in a circuiar motion from centre out to edge, to wipe the lenticular
from top to bottom in one continous swipe. Seemed to work great in getting
the kids fingerprints, etc off the screen. BTW one wipe over normally was
suffucient, had some customers attempt to rub out a scratch using the stuff,
actually began taking the paint between the lines on the lenticular off
leaving a nasty blemish. Strangle it was supplied as the recommended product
with many Phillips, Magnavox, Philso, and Sylvania RPTV units.

different than denatured alcohol, used as a solvent or shellac thinner. You
find rubbing alcohol (aka isopropyl) in drugstores, denatured alcohol in
hardware or paint stores.

early 80's. My dad and I actually built one of these, and it worked, although
we had to do considerable work to the set to fix the keystone effect, Also, the
picture was very dark, requiring an almost totally dark room to be able to see
anything, and the individual phosphor dots were clearly visible on the image...

Don't you have to reverse the yoke connections also? I like the picture with
the bright wall lights on - not likely!

Depends on whether you want front or rear projection, either way it's a
silly idea, there's much more modern ways to hack together mediocre
projection TV's these days, as well as a plentiful supply of old real
projection TV's, I've gotten 4 or 5 of them for free over the last few
years, and most required a lot less work to fix up than building something
from scratch would take.
