Re: Dirty Screen

You should be able to access the screen from behind after taking the back panel off.Also if you reach up inside the rear wall you can clean the mirror ad picture tube lenses. This will make a vast improvement on picture brightness and quality.

Removing a screen protector on a Hitachi 57F10A

You might try Hitachi for the service manual with full breakdown.

Basically the entire front screen unit comes off from the front in one piece, then inner two screens come out--carefully! and then frame needs to be partly pulled apart to get out screen from rear as it is in a slot all around the frame.

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.

Mitsubishi VS-6043 - 60 inch

These are fairly simple, remove the speaker cover and then remove the screws at the bottom of the screen, then the whole thing lifts up and off, be sure to unplug the front panel controls, this plug can usaly be found just behind the cover behind the speaker grill

Cobwebbs between the screen and the screen protector

Hi pykeman,

I have successfully used a feather duster taped to a vacuum cleaner extension tube with duct tape. Remove the back panel of your projection television, then remove the the rectangular panel near the top over the chassis where the cabinet exposes the inside screen area. You will see the red, green, and blue CRT lenses. Insert the feather duster through this rectangular opening and sweep your cob webs away from the screen. Works for me every time.

Dark blotches behind the screen

When I had this problem with my 52525 I cleaned the bulb with a lint free cloth. The dark blotches went away.

Inside screen seems to be getting dirty

I had the same problem until I removed the screen and cleaned the front mirror with a static feather duster. First, turn OFF power. Second, remove screws on rear at top and on both sides of the screen. Third, remove speaker grill. Fourth, remove screws on each side of the screen where screen meets the speaker area. Fifth, remove two screws in center area of speaker area under screen. Sixth, lift screen up and away from set housing and use a duster with a two to three extension and GENTLY wipe the noticeable dust layer from the front tilted mirror located behind the screen at bottom of screen. Seventh, do everything in the REVERSE and you're done. If you need to replace the lamp, now's a good time to do so. Also you should clean the dust filter located behind an access door on the rear (right hand side as your are looking at the rear) with a handheld type of vacuum device.

After I completed ALL of the above procedures my WD-62525 was better than I remember. I bought it in 2005 and the picture quality has never looked so good.

The screen is as light as a feather but 62" is awkward. It is recommended you use another person to hold the screen but I work best alone and it was a breeze.

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)
