Cobweb inside of TV

Hello. I have a Sony LCD/Rear projection TV and it has a cobweb inside the screen that is driving me crazy. We took out the bulb and cleaned the mirror, and blew out everywhere we could get to, but it is still there.....how the heck do you get to the back of the screen?

    I have found that i have a very elaborate looking cobweb inside my tv but it is too big and too far in for me to get to and it is going from top to bottom and from side to side (damn near touching the mirror thing in the back) just far enough in though to where i cannot reach it with anything and just want to know how to take it apart without damaging anything such as the mirror thing in back; dust-off helps a little bit but is just not powerful enough

    I don't think a picture would show it. You can really only see it if there are very light colors on the TV. It is stationary, but it appears to move a little as though it is being blown on. I will see though if I can get a good picture of it. Thanks!

    I guess my picture file is too large to post. Do you have an email that I could send it to?

Remove the front panel there is a thumb screw in the back on each end to remove. then remove the screws from the back along the screen. remove 4 screws from the front bottom of the screen. remove the screen and use a soft cloth to clean the inside cavity.

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!

Cobweb?


You'll need to have the frame of the tv either opened so you can reach in there or the top mirror block assy will need to be removed to get inside to the screens. You may want to have a Sony ASC do this type of repair. Call Sony for a referral.
