I have a Philips 55PP9401. It has a beautiful picture....While on, it looks like a cob web with some dust on it is being projected onto the screen. Is this possible and if so, can it be remedied easily?
Its a spideweb behind the screen. i had the same problem, take the back off (unpluged) and spray them out whith a can of compressed air. i thought mine was screen damage for a long time till i saw the spider walking on the screen from inside.

Re: Inside the cabinet projected on the screen?
Well . there are 4 things that can cause this..
1= the outer screens could be dirty.clean with screen protector cleaner.Spray on cloth and not on outer screens.
2= outside lenses of picture tubes could be dirty.Unit can be opened .Outside lenses can be cleaned with a lens cloth .Do not use paper towels or cotton as this my scratch surfaces of lenses.
3= inside of picture tubes could be dirty.This should be done by a repair shop only(dirty coolant inside tubes)

You may have mineral deposits on the inside of your screen or if it is a projection set then the projection lenes and or mirror has mineral deposits on it and or dust and or cob webs obscurring the image.
it is not reccommended for game console to be played on a projection t.v because projection tv's have three color bulbs in them and the conversion is different and if it happens to work it has been known to have burn the games image in the screen after awhile.. usually the store doesn't tell youthat unless you ask them about playing game consoles on a projection tv
I have successfully used a feather duster taped to a vacuum cleaner
extension tube with duct tape. Remove the back panel of your projection
television, then remove the the rectangular panel near the top over the
chassis where the cabinet exposes the inside screen area. You will see
the red, green, and blue CRT lenses. Insert the feather duster through
this rectangular opening and sweep your cob webs away from the screen.
Works for me every time.
First, repair convergence problem = replace both convergence
