I'm trying it . Gladbag would also protect phosphors from UV?

zenithfan1 06-29-2012 05:27 PM

Yes, it should and it'll also help it absorb more heat. Good luck!

I have thought about taking several out to death valley to get the lenses off. It gets so hot out there the trash bag would melt to the glass. The thing would be off in 20 minutes

Are phosphors sensitive to sun/UV esposure? Enlighten me please - first I've heard that.

Just a suspicion; I would worry about TVs in sunny shop windows.
But maybe tinted safety plate filters most UV like airplane windows
are treated to protect people from high altitude UV.

I've never heard of UV bothering them; I guess if they can stand up to being hit by electrons they can handle sunlight? Uneducated, though.

Some of us have mentioned this before in multiple posts. During the downtime between sunny days it wouldn't hurt to be soaking it. The PVA will soften up around it's edges but it takes awhile. I've had good success this way.

If it's the green halo type, then it wont work. Has to be the RCA type black moldy looking stuff. The green ones are a Pain in the a$$!
Snelson, yours does not need any work. No cataracts. Just clean and reinstall.

on the subject of the uv causing any problem ,are all phosphors made the same ,can being exposed to the sun for extened amounts time cause it to lighten ? there are more than just uv in sunlight ,i can see his concern if your not sure of something its better to safe then sorry,for years they said that if your computer is left on the same picture it could burn the image on the phosphor ,iv never seen one ,its a interesting question though.
