Taking apart and putting back the freznel screen of a Mamyia 220

When taking apart the Freznel screen of my C220 to clean it three small silver metal washers droppedout, but when replacing everything I was unsure of the correct positioning of three small metal washers, and two black cardboard spacers, one spacer is slightly thicker than the other.The spacers fit under the Mamyia logo and level out the focusing screen. Is an exploded diagram available to clarify exactly where they fit?.

Many thanks

Those are spacers for equal plane for all corners.

Without the service manual, then you are up the river without ...

Just try to put spacer(s) on one side more than the other and close it up. Now look thru the viewfinder with lenses attached and check for sharpness.

If you're doing lots of cloe-up or macro, then those spacers are needed. If you can't correct problem, just shoot at F5.6 or higher.

You will have to remove or add spacer(s) by using T & E methods.

I have a panasonic pt47wx49e rear projection television. On the bottom half of the screen there is a red shadowing effect that makes me think the convergence is off. Also there is a scratch on the outer...

I had the same problem with my tv. It is a convergence problem but if it has convergence settings in the menu and they don't fix it, you need to clean the lenses with alcohol and q-tips. I did it with the tv on so i could make sure it was clean by the absence of streaks on the lenses. The outer screen (if it is smooth) should be a protective screen (just plexiglass). You can get a replacement at a glass store be sure to keep the old one so they can cut a piece to size. It the screen you are talking about has little lines in it your freznel lens is scratch and it will be difficult to find a replacement. Good luck!

Screen has been pushed in 42wt29b

If the protection screen is broken, Just take it out and replace it with a sheet of plexiglass. If the freznel lens is damaged I believe you will have a hard time finding a replacement. Good luck.

You will have to remove the screws around the top and sides of the screen in the back. The screws should be 7/64" allen key. I took the protection screen off of mine because I don't have kids or animals. I would clean the plexiglass layer after removing it from the TV. If you get any bit of the cleaning solution on the freznel lens it will leave a very noticable spots that you have to work hard to get off. Good Luck!

Top left of screen looks warped as well as bottom. Almost as if something hit the screen, but the kids say it wasnt them. Tried the convergence feature on the setup, but that does not help in any way. Also...

has the screen been pushed in?
does it look cracked?

the reason the pic looks warped may simply be the magnifier screen (lenticular) behind the outer screen (freznel) has been pushed in giving the distorted look

if so and you are capable it is not a big job

however if either screen is cracked then it is an expensive job

Please Help with color & screen Cleaning

You are going to have to adjust the three screens in the front of the set behind the speaker cover. You will need to adjust the Red, Green, and the Blue all to look like a B & W picture so turn down the color or put in a B & W movie from a DVD or VCR. Then adjust each screen till you get the best blend and a good grey scale. Grey scale is the best B & W you can get on the TV set. The screen has two surfaces on it. The outside part goes up and down and is called the lenticular screen, and the inside part has round circular pattern too it and is called the freznel lens. The circular screen and the outside screen can be cleaned with a car polish cloth called a Shammey. Use deluted windex and only wipe the rag in the direction of the screen, eather up or down or circular. Good Luck

Image problems

this might sound odd but you might have a bug or something on your mirror or have you bumped the front screen? the freznel and lenticular screens could have seperated. i would contact a local repair shop for an in home service call just to verify these 2 possible scenario's.
