To clean the mirror and the optics, use a very mild solution of washing up liquid and luke warm water with a clean cloth that when in use is almost dry.

Side mirrors work some of the times


I'd start with checking the mirror switch. It's probably dirty or bad.

I can't find any documentation on how to remove the primary mirror for cleaning. I'm a newb and don't want to mess anything up. Thanks, Bob


First -- how do you know the mirror needs cleaning? Did you shine a flaslight down the tube and see some dust? Never use a flashlight to determine if a mirror is dirty-- they are ALL dirty when you use a flashlight to check them.

Only clean the mirror if it is interferring with the views through the scope.

There is a ring around the back-- remove those screws and the mirror should come out-- don't driop it! Then remove the mirror from the mirror cell.

The only thing fragile are the main primary mirror and the smaller secondary mirror anything else can be cleaned with Windex and or Pledge.

To learn how to clean the mirrors read this:

The mirror should be VERY dirty or leave it alone.

You must do this gently or you will scratch the mirror. Once the mirror is clean you will need to re-collimate the scope. Watch this video:

Receiver end of faxes shows vertical black line. I changed drum and toner also cleaned glass scanner. I do not have a glass flatbed scanner only an automatic feeder.


The cause of this problem is usually a dirty scanning glass (there might be ink or white out on the glass). Check the glass really closely or the cause could be dirty optics or a bad CCD board. There are mirrors underneath the scanning glass. Dirty optics can cause lines when faxing or copying. If you can not access these mirrors, they would have to cleaned by a technician.

Dirty primary mirror


Nice telescope! I clean mine with a dust blaster, those canned air things.They are cheapest from Sam's Club, if you have those near you.Be careful if you decide to use swabs, you may scratch the mirror or remove the special coatings on the mirror.Try the canned air first.If you do use a swab, exercise great care.Use nothing metal.Maybe a long plastic spatula with a soft , lint free cloth.No solvents.Good Luck

Hi. I had the same problem with my Philips RPTV and the fix is extremelly ease. You just need to open the back cover (mine uses torx screws). Inside the tv is very mechanic. You will find the three CRTs and most likely the lenses are dirty. You just need to wipe them off with a soft cloth. Also the CRTs project the image not directly to the screen, but to a big mirror and that mirror will be most likely dirty (like when you open the hot water in front of a mirror). Once you clean the mirror and the crts, your tv will like as the they you got it.
