Remove pointy screws out of back of screen ( 3 up each side and 4 across top). remove speaker grill, remove 4 screws from center cover. remove 4 screws from bottom of tv, disconnect wire bundle. lift screen up and off. clean mirror facing up and lens. Do NOT touch big mirrror, trust me. put it back together by sliding screen back on and making sure all edges are flush before putting screws back in. the pointy ones go in the back every other screw is flat. good luck, should only take about 5 minutes.

I have an 60PP9202 Rear projection HD TV and the inside of it needs dusting. Is there any instructions available on how to do this? The unit was purchased in 2004 and was vaccumed several times on the back...


You will need to remove the back cover. Here you will dust the lens with a pressure can of air only. Then you proceed to clean the lens with an eye glass damp cloth Get these from an eye doc). As for the mirror, you must use real caution. This mirror is made of a stretched plastic. The best way to clean this is to use a new feather duster. Do not even think of using anything wet to clean this mirror. It is very fragile. Let me add, that you want to do this from the rear also. Next, I would not recommend you try to pull the front cover (screen) off. It would be next to impossible to put the screen back on the TV. You will also feather dust the inside of the screen from the rear. No wetting solution here. Be sure your TV is not plugged in. Thanks for asking and show all hands of support!

Need to take apart a Toshiba 57H83 for cleaning


This is fairly easy to do.

You will work from the back of the tv.

Steps:
1) Unplug the tv and wait a ten minutes for components to discharge.
2) Take the back panel off which is the brown pressboard with all the holes. Probably about 12 screws for that tv.
3) Take the back top plastic shround off if you want to clean the mirror. There are about 15 screws around the perimeter of the shroud, and maybe two in the back.
4) gently lift the shroud off the tv, it will have the mirror attached to the back of it so be gentle and careful.
5) lay the shroud on the floor so you can clean the mirror with window cleaner or non-streaking solution.

6) with the shroud off you should be able to see the tops of the CRT lenses covered in dust. Clean those gently. Do not bump them or turn the lens in any way otherwise you may need to do some re-alignment and/or re-focus of the CRTs.

7) DO NOT USE window cleaner on the back of the screen or front of the screen. You should get screen cleaner solution for this specifically. It might be best to just vacuum the spider webs off the screen and not clean it if you don't have the screen cleaner handy.

To clean the dust off the circuit boards, here is a tip:

With a clean soft paintbrush and a shop vac, or house vacuum, use the paintbrush and lightly brush around the components and on the circuit board. Have the vacuum hose right next to the paintbrush so it sucks up the dust as you stir it up. BE GENTLE on the components.

Stay away from the CRT necks and do not use your fingers. Remember the CRTs can still be carrying a good electrical charge, so best to avoid them.

Re-assemble the tv after everything has been cleaned. Figure it will take about 45 minutes if you haven't done it before.

My mitsubishi 65-inch dlp tv has white spots on the screen. What are the problem and solution?


It's either mirror hinge fatigue or dust on the inside.
Mirror hinge fatigue can be fixed by putting a solid color picture (white or gray works best from what I understand) on the display and letting it sit for 20 minutes.
If it's dust, someone is going to have to go in there and clean it out.
Also could be a defective micromirror device.
Try the first suggestion and if it doesn't work, you're going to need a technician to take a look at it.

I was wondering if u know y my mitsubishi tv wasnt showing a clear picture i replaced the lamp with new one but it still shows a dark picture


This may be a model that has two mirrors. Mitsubishi could tell you if this is the case.

Some idiot had the bright idea to have optical unit shine picture into tiny mirror which puts it into large mirror in back; problem is tiny mirror if there is at bottom and facing up, dust or dirt get on it and picture brightness will diminish up to 70% or more.

If model you own does have two mirrors, the front of the set with the screens will have to be removed to clean it, not real hard and takes 15 minutes.

If you can confirm it has two mirrors I can tell you step by step how to remove screen unit and resolve problem. Usually if tiny mirror dirty it will happen over time, picture will gradually get darker and dull looking.

Let me know if want instructions, the set either has two mirrors or it does not.

Mitsu 65" DLP-picture seems washed out


Most likely cause of your trouble is dust on the small mirror inside you set. Your DLP set has 2 mirrors not including the DLP chip itself which has about 500,000 tiny mirrors. The 2 mirrors reflect the DLP chip image to the screen you view. The first is the main suspect it's about 4inches by 7inches. It's mounted on the bottom center facing backwards. This mirror faces slightly up and somtimes after time dust, smoke, dirt settles on it . The second fills the space of the entire back of the cabinet but it faces down and takes alot longer to get dirty.
The compartment is sealed but dust seems to find it's way in. If you remove the screws that secure the screen assembly from the top , sides and bottom. Make sure to have a friend available the screen assembly is delicate when it's not mounted to the cabinet. You can remove and clean the mirrors. These mirrors are glass and you can use glass cleaned. Don't use glass cleaner on the screen it's plastic. You can clean it if necessary with plastic cleaner only. Probably not needed.
Good luck.

Cleaning the bulbs and mirror on my Mitsubishi 55" WS-55313 TV.


You should re-consider having a tech do that for you. The access is by removing the screen assmbly which are somewhat fragile. If you want to give it a try, pull the speaker grill off, it comes off just from pulling it, there should be five screws across the bottom of the screen assy, remove those, there is also an access door on the front of the set with four screws, that has to be removed to unplug the cable that goes to the screen sensors. The screen assy has to be lifted straight up an inch or two and then you can pull it forward away from the set.
As far as cleaning the mirror and lenses, you can't get to the face of the tubes so it's the top of the lenses that you clean, just use a soft lint free cloth (cloth baby diaper) and wipe the dust off the lenses, you can slightly dampen the cloth with water if necessary, same type of cloth on the mirror and you can use a glass cleaner on it just don't press too hard on the mirror.

Cleaning of mirrors


i have been fighting a dark screen almos impossible to see dark scenes

i found this from another person
the mirror has dust on it easy fix
remove front of screen by removing screws around the top and sides of the back don't forget to pop off the bottom cover in the front it just pulls off
then remove center cover screws
i could not disconnect the front electrical plug but it has enough slack to lift and then tip the front screen down to the floor
it will be obvious on the mirrors there is a big one it wasn't to dirty
lean in and look down there is a small mirror and lens they were filthy
there is a piece of foam trying to keep the dust out it was sucked backed so dust could get in
clean with windex and paper towels cloth didn't work
good luck

Large dust circle on a Toshiba 50H95 RPTV


No the front panel will only give you access to the CRT circuits. Remove the back panel. UNPLUG your set. You should be able to reach inside (its a stretch for sure) to clean the screen, clean the tubes and if you reach up behind you can actually clean the mirror. This will greatly improve your picture. Do not use windex just a damp soft cloth then dry with a soft cloth. The mirror cleaning is most important to get a nice bright picture. Over the years the mirror tends to get dull. Hope this helps.
