Cleaning lenses on projection tv


Have the set unplugged please.

CAN BE DONE FROM REAR--from the front is a bit tricky and dangerous---from rear with rear cover removed locate the three large black lens( hard to miss them) and clean them with a lens cloth or a paper towel with glass cleaner sprayed on it.

Depending on how much dust===should be done one time a year.

I am replacing the bulb in my three year old DLP television. The replacement is straight forward. I wanted to know if there is any preventative maintenance I should do to the mirrors, lenses, or cleaning...


No. Just keep you house clean and vacuum often . Keeping dust and dirt to a minimum is the best way of keeping the fans in the tv from drawing that dust and dirt into the tv. Also cigarette smoke will destroy this type of tv. If you ever get a dark spot in the picture it may be dust on the lense. You can dust the lense with only a microfiber rag.

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.

Our samsung projection tv has occasional blue marks on the screen, which is recent. Is this a problem with the tv? or something to do with Directv?


I suspect that it may be just dust particles on the projection tube lenses.
Take the front off and clean the dust off the lenses.
I hope this has been helpful

Mitsubishi wd 62527 has very dark picture changed


Clean the small front projection mirror. That mirror can get dust on it and will cause the projected image to appear dull and dim and cleaning that mirror will usually restore the brightness and crisp details in the image.

Dull/cloudy picture


If the set is 4-5 years old, it probably has dust on the lenses and mirror.
This can cause a murky picture.
If you can remove the front screen assembly, you can gain access to the lenses and mirror. Clean with a dry micro-fiber cloth very gently.
Hope this helps,
Dan

I have a RCA 60 inch TV and its about 12 or 13 years old. It has never been serviced or cleaned on the inside. The problem I'm having is the picture is starting to fade (quite a lot)and I was wondering if...


you probably have a little of both. the shutting off is definately heat related but could be too much dust on heatsinks, etc causing it to shutdown. cleaning may eliminate problem but could be a sign of an underlying issue..
the dust can really cause the picture to dim. most of these tvs you can pull the "lightbox" or guts out of the cabinet to clean all 3 lenses, and clean the mirror if needed. don't mess with the screens except cleaning the front from outside. usually a 1/4" driver will be all you need, and a soft cloth for the lenses. use compressed air or a vacuum to clean out dust which will help with cooling, but the picture is only effected by dust on lenses, mirror, and screens.

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!

Epson livingstation 45" tv


I just fixed the problem on my epson 57" living station. The picture is like new. Yo have to clean the dust off of the the 3 lcd lenses. (I'm not sure if thay are actually called lenses)
You can get to these by entering thru the front of the TV. Yes the front. You must remove the screen. There are A LOT of screws. This screen housing covers the entire front of the tv. and you have to remove the back panel and ALL the screws on the back of the tv to get it off. The only electronics that have to be disconnected are the Speakers and the front control panel. They both have snap connectors. After you remove the entire front panel which houses the screen and expose the inside mirror you will see more screws. You must remove those as well to remove the mirror housing. DO NOT REMOVE THE MIRROR FROM THE HOUSING. Note that there is a peg that is next to a screw in thre front of the mirror housing thst you must pull the plastic housing out in that area to release it.After you remove the mirror housing you will see the 3 LCD panels or lenses. YOU DO NOT HAVE TO REMOVE ANY ELECTRONICS OR SCREWS AT THIS POINT. Use a can of compessed air to spray the dust out of this area. I used a vacume to catch the dust as it flew out in the air. Try to hold the can as upright as possible.Keep hitting it with the air until no more dust comes out. Put the tv back together. As you open up the tv you will see dust everywhere. I took the oppurtunity to clean as much as I could. The Mirror though was clean an I was afraid to touch it.

I am a Construction Salesman yet fairly handy. I have no electricle experience. This took me 2 1/2 hrs. I spent the first 45 min. trying to get to the lcd panels from the back of the tv. Don't waste your time. You can't.
