Remove front speaker grill(s) at the bottom of the screen behind the speaker grill you will find four or more black screws hold the bottom in. Look carefully to see the front keyboard needs to be unplugged---usually one or two different size plugs; you may have to remove the inspection plate located in back of the speaker grill to get to the point where they can be disconnected, with the keyboard disconnected the entire screen lifts straight up(you need to bring it up 3-4 inches and then it comes straight out(there are two hooks on either side that it goes into--when you finish line up a little and slide it back until it is back in place.

Clean the mirror with glass cleaner and the lens can be cleaned with a lens cloth or with a paper towel with glass cleaner sprayed on it.



Replace the screws and the speaker grill unit for the set.

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.

Sorry you are having trouble.
This is very common problem.

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

I have a Mitsubishi WS-65413 65 in. Rear Projection TV. This has been a great TV with no problems as of yet. My concearn is its getting up there in age and I wanted to purchas a new lamp for the tv. I just...


WS-65413 is a Mitsubishi set first made in 2003. It uses three picture tubes and no lamp or bulb.

About the only problem these sets ever have in them is failure in the convergence circuit--it happens with age.

If the picture looks good about the only service they ever need is to have the lens on the three tubes cleaned about once a year--if the lens are dusty the picture will be somewhat darker and dull---gradual change--It also has a large mirror that depending on if you are in a dusty environment can be cleaned as well.

Usually the mirror because of the way it is mounted does not need cleaning. Two ways to do this:
If you just want to clean the lens turn the set off--UNPLUG IT and remove the back cover--you will see the three large black lens units---clean them with a lens cloth or a paper towel with glass cleaner sprayed on it.

The other way is tricky as you have to remove the entire front screen assembly--most of the time you have to remove the speaker grills, and inspection plate and unplug the front keyboard---four or five screws along the bottom of the screen unit secure it and with them out you lift the entire unit up(good idea to have 2 people do this and not flex it--you can dislodge the screens from the frame if you are not careful) and out.

What I usually do is remove the back cover and stick my head in and look at the mirror from the inside of the set--if it looks clean without grime or dust--let it be and just clean the lens.

If you want to improve the sets picture after you put everything back--go into the customer menu and select convergence--there will be instructions on screen telling you what to do--select advanced convergence and with the device or input button go to a unused video input----look at the grid of lines--if red or blue are off a little you can adjust with the Mitsubishi remote--the better the convergence is adjusted the better the set will look.

Usually if not any circuit problem---cleaning the lens, mirror, and adjusting the convergence is all that needs to be done.

Rear projection tv picture quality loss


most of these sets have 3 lens for the three picture tubes inside and also a mirror---if it has never had the lens cleaned they could be dusty and this will diminish the brightness and clarity of your picture---if real dirty the picture will look washed out------most of these sets you can remove the back cover(unplug set first) and gain access to the lens ; clean them with a lens cloth or a paper towel with glass cleaner.

I need to clean mirror


Most rear projection sets the screen will pop off the front. Usually a couple of hidden catches. Get another person for this.
Once off you can clean the mirror but not the inside of the screen.
Unplug tv first

Cleaning mirrors and lenses on Sony big-screen projection TV


it's fairly easy to remove the screws on the back bottom portion of any rear-projector television. when the bottom part is removed, you will see both the mirror and the 3 lens. isopropyl alcohol or windex should do an efficient job. a soft lens rag can be found at any camera store. i'd spray the lens rag instead of the actual lens or mirror when doing this job.

Focos is bad


Not good for a non qualified service personnel!
WARNING! focus is close to the HIGH VOLTAGE!
Consider this.... if your TV is more than 5 years old, it maybe the crt is gone?
Those TV has self focus... nothing to adjust what so ever?
Try cleaning the inner lens... might help?
