- My Philips Proscreen 4750G filter did the same thing just last night ... came out in pieces and powder. I stripped all the old stuff off the filter frame and cut the toe from an old pair of panty hose, then slipped the frame inside and slid it in the slot. Works like a charm.
1. I know my projector gets warm, but not hot, where the filter goes, so I wasn't worried about melting. Your unit may vary ... the foam that belongs there is significantly more resistant to heat than panty hose.
2. Panty hose are thin and liable to snag on things. Have a care putting it in that it's not torn in the process. Best approach is to try it and pull it out, then see if it's in one piece to get feedback on how it inserts. May use more panty hose, but save the projector, which sounds like a bonus to me. (wink)
3. My particular projector has a switch way inside that must be pressed before the unit will turn on. The first three times I put the panty hose filter in, the seam on the toe prevented the frame from inserting fully (the tolerance is that close), and the projector wouldn't work. After tearing that one putting it in and taking it out over and over I realized what was happening and moved the seam (using the other toe) to allow it to work.
P.S. Ronomy is a real gem. He's sending me some filter material so I fix it "right". But this *works*, and it's how my projector is being used in the meantime, so I thought I'd toss it out there for when he's run out. (grin)
