You must be very careful when cleaning the mirror, it is not like any other mirror as the silver is on the front of the glass. I believe that Hitachi's are made of glass and not mylar.
Do not use a glass cleaner, as they have drying agents in them.
I try to avoid cleaning the mirror unless it is really dirty. It is very easy to leave streaks on the surface.
Most likely you would be well served by using a mild detergent in a bowl of water, a soft cloth, (I like to use cloth baby diapers) anything that is lint free. Do not let the cloth drip into the set.
Clean the surface with the damp cloth and dry with a clean dry cloth.
Try to use the dry cloth to remove any streaks.

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

Remove tv screen from hitachi projection tv


The entire screen unit can be removed but first remove rear cover and look at the lens--clean with a lens cloth etc----peek up inside and look at the mirror--if not dirty or smudged just clean the lens.

removing the screen with its frame can be tricky--easy to damage the screens etc. Removal usually requires front speaker grill to be removed first---most just pull off but a few are secured from rear by some screws.

With it off look to see if at bottom of screen there are a row of screws--if the entire front unit can be removed it will pull out at bottom and be snapped in place.

A better suggestion is look at rear of set above back cover--if the upper part is plastic--it with the back removed can also be removed--careful as mirror is bolted into it---that way you can clean the mirror and get at the lens for the tubes without trying to remove screen unit--some of the smaller sets this is the ONLY way to get at the mirror.

Yes a number of screws but if plastic upper rear comes out with mirror much easier and safer way.

I have a hitachi 55vf820 lcd rear projection tv. How do you get the cover off to clean mirror?


Don't try that as the mirror almost never needs cleaning and MUST be cleaned with a special cleaner---leave a single fingerprint on that mirror (or a smudge) and it will stand out in the picture like a sore thumb.

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.

My tv has been getting darker I"m guessing it the mirror or the bulb is going out


It would most likely be the bulb. however open it up and see if your mirror or bulb are dusty, as this can also cause a decrease in brightness.

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:

CAN I CLEAN THE MIRROR ON MY HTACHI 43FDXOIB TV


With the set unplugged remove the back cover of the set.

Next remove all the screws on the entire large plastic shroud that is black in color; you will notice hand holds to lift it free and the mirror is attached to the inner side.

l usually use paper towels and glass cleaner to clean it and also clean the three large black plastic lens in front of it. It either is dirty or grimy the picture will be affected.


Carefully replace the mirror/shroud unit and put all the screws back that secure it.

Replace the back cover and see what it looks like. There is no access from the front of the set to do this.

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.
