Start by taking off the front bottom cover, usually they have screws way at the bottom one on each corner, then uncrew the screen usually there is 3 screws at bottom of screen pull up and out on the screen the screen has small screws in the inside all the way around take them off once you reached screen take it out and split it in half clean it with dry rag then put everything back together exactly the way u took it off before you screw the screen back clean the projectors with dry rag and the mirror with windex or any glass cleaning product.

Scratched plastic screen protector


I have a rear projection TV that I thought had a scratch as well. Upon closer examination and several attempts to clean, I discovered that there was a spider web behind the screan in front of the color projectors. I carefully removed the screen and gently cleaned the spider web from the screen. Presto no more scratches.

Hope this is a viable solution for you as well.

51" Philips Projection Wide Screen. Want to know


Almost all the Philips projection sets have a large black plastic shroud on the top half of the back of the set----it can be removed--most of these sets use torks type screws (star shaped).

With the upper part on the back removed you will find the mirror is suspended---do not try to clean it--it is film like handy wrap and will not need cleaning.

I use a swiffer type duster to reach inside the set to remove any spider webs etc, If dead insects or dirt inside the screen use a very soft cloth with water (just dampen the cloth slightly)

Usually you are seeing spider or cob webs and the duster will get them all--DO NOT APPLY FORCE IF YOU WIPE THE INSIDE OF THE SCREEN AS IT IS EASY TO SCRATCH IT!

Cleaning webs from inside screen


There are two ways to do this---the hard way which is to remove the entire front screen OR

What I do is (with the set unplugged) remove the back cover of the set; you should see the three large black lens.

Most of these sets there will be enough room to get a swiffer duster up inside to gently catch and remove all the spider webs. If there is not enough room let me know and I will tell you how to remove the front screen.

Also---if you can see those large black lens---clean the dust off of them with a lens cloth or paper towel with glass cleaner sprayed on the towel.

If you can reach the webs from the back do not exert pressure when you wipe the inside of the screens---easy to scratch them.

If you have questions let me know BEFORE you attempt this.

If this helped or told you something you did not know rate this solution as very helpful as I do this here for free.

How do I dust inside the screen of a Rear projection TV?


Unplug tv first Usually you can pop the front screen off the set. There may be two hidden catches depending on the model. You may want to use two people for this. Once the screen is off removed the spider web and clean the back mirror with some windex, don't clean the inside of screen with any cleaner. Replace carefully the screen making sure it clicks back correctly

Hitachi 51UWX20B spider web like lines help


I know my response is a while after you asked, but to clean the inside of the tv case is pretty simple.

Remove the bottom speaker cover...on this model you just pull it off. There is no clips or screws.

Once the speaker cover is off you will see the bottom of the screen, there is 4-5 screws on the bottom on each side....I think 4 in the gray plastic and 1 in a black metal strap. With all of those screws out pull out SLIGHTLY on the screen and push up. The top is held in with a down force clamp and you are just popping it out of that....It will pop back in once you are done.

Now clean the back side of the screen, the mirror and CAREFULLY dust off the lenses. I myself did not want to use any cleaners (to avoid streaking) so I used a new microfiber dusting cloth. My picture became brighter and the "crack" that I thought I had was just a dust web....

Hope this helps and good luck

Spider web inside tv


You need to open and clean it carefully.
  1. remove the back bottom panel
  2. Remove the top back panel (carefully the mirror is on it)
  3. Clean the mirror and the lenses (on the mirror don't use products with ammoniac) "a good tip is to use same staff to clean photographic cameras"
  4. Place back the top rear panel
  5. place back the bottom rear panel

Dirty screen but it is behind the outside screen.


The front screen with the frame does remove from the cabinet giving you access to the mirror and CRT lens. Remove the speaker grill,remove the four screws on the bottom of the frame, then working underneath a corner proceed to pop the rivets holding the frame to the cabinet. It will seem impossible at first because you have to use a lot of force to pop each one out.When reinstalling,a rubber mallet may help popping each rivet back in (I am not kidding when I say they are tight)

Spiderwebs under Screen, how do i clean it ?


Yes, I have seen this many times. Usually the best way is to remove the upper back cover and clean out the spider webs with a soft, dry cloth, but be careful because the mirror is mounted to the inside of the cover.

Trying To Remove Screen


I have a panasonic 53 inch and have had the same problem on numerous occasions. I removed the backing of the television, stuck my vaccuum cleaner hose inside the tv and sucked out the spider and the web.
