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.

Dc59 I removed the clear canister but the inside with the chambers with a mesh cover are filled with a fine powder. How to I clean?

I have the same buildup of very fine, powderlike, dust/dirt particles behind the mesh screen.

I do not doubt your technological explanation as to why/how this accumulation has occurred but there is another issue created by this buildup and an concern to go with it.

The issue is that this accumulation literally stinks. We have 4 cats and a dog which is likely why there is such an odor. There must be a way to remove this stuff.

The concern is that, after putting up with the stinky Dyson and the continued accumulation, the "dust" will eventually completely fill the space behind the mesh screen. When that screen is completely filled is the only solution we have is to spend another $600 for a new Dyson?

The Dyson is not your typical disposable technology that we often buy today. We chose to spend the extra $ for the Dyson because of the spirit cleaning of the unit. Had we known the unit would, within 6 mos., begin to stink and would likely need to be thrown away within two years we would have purchased a less expensive brand.

Since we have learned now that Dysons are stinky and disposable units we can run it under water, let it dry and hope for the best?

There is dust buildup behind the control panel due to the openings in the vent trim. I'm worried the dust may eventually cause a short, etc. in the electronics. What is the best way to clean this ar

Use a small rubber hose or flexible tube and place one end near or on the dust. Blow thru the other end. The dust might have some grease in it, use toothbrush or small long bristle brush, similar to a baby bottle brush but much thinner, to help loosen dust.
Do not add insulation!!
If it's a convection oven, the vent might be intake. Most vents are exhaust. Does heat come out of it during use?
Is it fan induced? Put a piece of paper near it, does the paper get sucked in or blow outward?

Freezer compressor gets hot

Check behind and underneath for dust buildup, sounds like your compressor needs cleaned on the outside, the dust is causing it to overheat and retain condensation, hence the ice buildup. Easy thing to check, good luck.

There is something like fog in the corner of the screen projected by DS+8K.Could you tell me what's the matter ,plz

Hello :

What you are seeing is dust on one of your LCD panels. Try pausing your image so that these abnormalities are clearly visible Then simply de-focus your projector in BOTH directions . You should see these blobs actually become a solid object either in the form of a string of lint or a spot of dust. If this is the case , then I recommend you to contact the manufacturer or the local dealer .

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..
