Remove speaker girll.No screws to remove grill just pull off.At the bottom of the screen frame you will see 4 1/4 inch screws.Remove screws and lift screen straight up.Clean cob webs and clean off lenses.I do not reccomend cleaning the mylar mirror.It is very delicate and you will scratch it.You can use windex to clean lenses.Good luck.

Hi, my name is Frank. My 55VF820 LCD Rear Projection Television started out with tiny little blue mega pixle dots in about a ten inch c-shape in the corner of the screen. Can still watch the TV, it seems...


Hi Frank, Your problem sounds like the projected image had been distorted by dust. Make sure your lamp is clean, then the lens, and then check to make sure there isn't any dust on the lcd itself. Good Luck!

We have a particularly long cob web right inside the screen of our Mitsu VS-60609 that's become quite noticeable. any way for us to remove the screen and clean behind it?


Yes , you can gain access by removing the speaker grille that pops off by grabbing it in the corners and pulling it out . Once removed you will see wires that come from the bottom of the screen trim and going into an access panel in the middle where you removed the speaker grille from . Make sure the tv is unplugged and remove the access panel and there should be two clips that need to be unpluged so when you remove the screen these to not pull out from the boards . Now you should see 4 to 5 phillips screws along the bottom of the plastic srceen that need to be taken out . once out now the screen can be removed . Now the screen slides on and off by pulling it upwards by grabing the plastic trim sides . It might be snug . Now some sets the bottom piece comes outward then up . Try the this previous suggestion first . Once off remove the cob webs and clean the three lens while your there to remove the dust buildup on them with a soft slightly damp cloth not pressing hard then dry it off with a cloth that is not damp . Make sure when putting the screen back on it slides back in the hooks that were holding on and the screw holes should line back up and connect your two cable clips back on and put access panel back on and speaker grille and your problem is solved . Good luck let know , thanks Team tech

Looks like dust behind front glass on phillips 46pp8621


The only way to remove the dust and or spider webs from that area is to remove the front bezel assembly and separate the protection screen, it's better to leave a svc. co. do this because the two screens behind that are very expensive. Hope this helps..

Dust behind screen


2 ways. There are two access panels about mid screen on the sides of the cabinet. Or you can take all of the screws out and take the whole screen apart ,all the way down to the lens on the projector. It is up to you. If you are pretty mechanincally inclined then take the whole cabinet apart, as you will be able to clean more of the cabinet. Use a microfiber cloth to clean both the screen and the rear mirror. Hope this helps. I usually clean mine every three months or so.

This may be caused by the high voltage arcing inside the set. This is most commonly caused by dust buildup on the electronics. A thorough vacuuming, with the set off & unplugged, may cure the problem. Use care not to disturb any of the components inside, as many are delicate. Compressed air(30PSI max.) may also be used.
