How do I get in there safely to clean the mirror?? what do i unscrew first etc.. it still working just fine but the color is going after 15 years and i need to clean the inside.


Hello.
I would not recommend you to touch the mirror. It is hanged sort of reflection surface facing down so it is not real dust collector. You can clean lenses of your CRT tubes (red, green and blue) to improve your picture. Just remove rear cover taking out black and golden screws and you will see dusty lenses right away in the middle of the TV. Use DRY "Bounty" paper towels to remove dust from lenses, don't wet it with any solutions or it will leave film on optics. Just in circular motion move dust to the black plastic edges of lenses. Don't worry about some specs of dust that inevitable will be left behind - they will not affect image at all like thick layer of dust do.
Regards.
Russ.

Sorry you are having trouble.
This is very common problem.
Do you feel comfortable looking inside with the power off?
Most likely the lenses and or mirrors need to be cleaned.
For the mirrors we use Windex or similar cleaner
For the lenses I recommend lens cleaner from a camera shop
Yes this worth fixing. If you dont feel comfortable doing the cleaning yourself just call a serviceman

Cob webs behind screen


The frame around the screen just pops off. Unscrew the plastic holders from the chassis frame and the screen will come off allowing you to clean everything inside easily. The "2" thin screens are easily cleaned and put back on easily also. Don't do what I did and think the screens go into the front slot of your plastic brace, they slide easily into the wider slot. You'll also be able to clean the dust from the reflector and guns with Windex. Much better picture after wards, trust me. You would be surprised how much dust may have accumulated on the lenses.

How do I remove the screen to access and clean the picture tubes and mirror? Pioneer SD533hd5


Before starting, it is a good idea to disconnect the power cord for your TV from the AC wall socket or power bar. Remove the back cover from the TV. Unscrew and remove all the wood screws holding the back cover on. Grasp the bottom portion of the back cover and pull straight back approximately 4 inches. You may require assistance from another person if you are of small stature. There are two plastic tubular portions at the bottom of the back cover that insert into the particle board enclosure and if you don't pull straight back, you risk damaging the back cover and or the enclosure. The mirror is fastened inside the back cover and will come out at the same time. You will then have access to the CRT lenses and the mirror for cleaning. I would not recommend removing the mirror from the back cover for cleaning. It can be done while in place using a clean, soft, lint free cloth and a very mild soap and water solution. Just be certain not to leave any streaks. The lenses can be cleaned with a lint free cloth and alcohol or a camera lens cleaning tool. Take care not to touch the lenses with your fingers.

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!

Cleaning the Mirrors and Lenses Rear Projection Sony KP 53S15


Do not use water or vinegar. use a can of air spray first just as you would use for your computer. Once all the dust has cleared then use a wetnap with vinegar. Not too wet though as you must remember that vinegar is an extractent. Meaning it will not take much to clead those visible parts and mirror only. bulbs may need to be taken off and yes open from the rear of the unit.

Screen is dim and not very bright


You can safely clean the mirror and lenses, it can greatly increase your picture if its dirty. If you unplug your tv you can safely remove the back and gain access to the lenses. All it takes is a philips screwdriver. After you remove the back, you can remove the light barrier between the upper and lower half to free up some room. Take a dry scratch-free cloth and wipe the dust from the lenses. If they're grimy, use a little lens cleaner (liquids used sparingly here, electronics don't like liquids, be careful) You can look up into the top and see if the mirror is dirty. A flashlight shined on it will illuminate the dust/dirt if its there. If you don't smoke you likely won't need to clean the mirror, but it may need it. Use windex or similar for tough grime.. I can usually reach up to get the whole mirror but I've heard of using a swiffer mop to reach the top. Removing the screen is difficult but possible if needed to get inside. Don't touch the back of the screen but lightly with a rag to get cobwebs, etc.

Old hitachi


the coolant most likely needs changing in the CRTs. Another possibilty is the mirror has become dull. use a damp soft cloth to clean the mirror then dry also clean the CRT lenses . Dont use windex. You will be amazed the difference just polishing the mirror can make in picture quality. Looking into the CRT lenses while they are on will tell you if any groth are present in the CRT coolant chambers.
