Just start unscrewing the back until you can get into all the areas. Please unplug the tv first and press power repeatedly for 35 seconds to help discharge the capacitors. You should use the wand on your vac to **** out all the dust and webs at least once a month. The top of the lenses that shoot toward the mirror and the mirror should be cleaned with windex.

Cobwebs proscan ps56700 inside screen


It can be done from the front but from the rear is actually more easy and safe--removing front screen and frame entails some danger of damage to the screens.

I have over many years of outside/home service calls encountered this.

As a outside technician I want the quickest and safest way to do this.

With set unplugged simply remove rear cover:

Use a swiffer type duster to reach up and inside and gently get all the webs out(do not use force when against the inside of the screens) and if the handle is long enough you will be able to remove all of the webs.

Also when doing this you will see with cover off 3 large black lens at the top of the chassis above the circuit boards.

They are the light source for your picture--clean them with a lens cloth or a paper towel with Glass cleaner sprayed on it---Do not attempt to clean the mirror in the rear as it is a film material and is easily scratched.

If the lens were dusty/dirty and then cleaned the picture will be brighter and sharper looking----that should be done about one time a year.

COBWEBS DRIVING ME CRAZY INSIDE MY SONY TV HELP!


Easy way to deal with this is to unplug set and remove back cover-----with one of the Swiffer type dusters(there should be plenty of room inside this set) gently reach up and get all the webs out---also a good idea if you do this with a lens cloth or paper towel with windex clean the three large black lens you will see when you remove the cover---they usually need to be cleaned about once a year(if they are dusty the picture will be darker and not a clear)

If this has been helpful give me a vote here.

Cleaning cobwebs from philips rear projection tv model 51PW9363/1


I had the exact same problem and the fix is easy to do. Unplug the TV first of all and wheel it out so you can easily get to all of the rear screws.

  1. Remove the screws from the ventilated back panel (the piece of wood with a bunch of holes in it surrounding the AV connection panel.
  2. Remove the wood panel you just unscrewed.
  3. Remove all screws from the upper plastic case on the back.
  4. Remove the back plastic case carefully. This is a little tricky due to two metal pins that it hangs on. Lift it upwards and you should be able to free it from these pins
  5. At this point you should be able to see the entire workings of the TV, and consequently the massive amount of dust that has accumulated.
  6. Carefully take a vacuum and remove all the cobwebs, taking care not to bump the mirror or the lenses.
  7. First, I used some compressed air to clean off the lenses and then used a clean microfiber towel to remove all the dust from the lenses, the mirror, and the screen on the inside. Make sure the part you are wiping the mirror and lenses off with is free from any dust or dirt or you will risk scratching them.
  8. Reverse the dissasembly process to put the case back together.
  9. I went through the convergance settings at this point and found that they were all out of calibration and as such recalibrated them. Use the mulitpoint calibration for best results.
  10. Enjoy a much cleaner brighter TV!
