Question about Epson Multimedia Projectors

Blue on one side

Blue on left side and a small amount on top.

Where in the world can I find books or any media
that give general instructions on diganosis and
repair of lcd projectors?

I want more information beyond what is found in
service manuals. I have searched but cannot find.
Surely there are technical books on projectors.

Your kind assistance is appreciate.

Hi and welcome to FixYa,

Rather than search for diagnostic and/or repair procedures and as you posted elsewhere, technical books on repair of LCD projectors, may I offer an alternative? Consider DIYs (do-it-yourself) projects. These are how-to as performed by enthusiasts who build their own LCD projectors. To shorten your search, the following may interest you:

The idea is to forearm you with practical workable ideas that perhaps could be translated to a repair project.

Good luck and thank you for using FixYa.

Searching for signal


The problem is with the computer, not the projector.
There are special function keys, generally with blue lettering along the top row of your keyboard. Find the one that looks like a double screen or says "CRT". Also locate the blue function key [FN], probably on the lower left on the keyboard.

Press, and hold, the [FN] key and press the [CRT] key to change to dual screen.... and wait for several seconds for the projector to detect it. If it still doesn't work after you have waited, press the key sequence again (there are 3 different screen settings).

1. Computer Screen only (normal)
2. Projector Screen only
3. Both Computer AND Projector screens

with the projector off, remove the cover and unplug the blue lcd panel ribbon cable from the main board and reinsert it. you have to unlock the cable first (either the clip goes up or out, but do not force). if that does not solve the problem, you have a faulty lcd panel.

Blue on one side


It isn't the LCD panels, it is the Polarizers that degrade with heat. You can replace them yourself.

Hey there, my Sanyo PLV-Z2 was starting to have blue dust on the image, so i decided to clean the lens and remove the lamp for inspection ,everything fine , but when i reinstalled my lamp the blue had went...


( hope this doesn't sound too simplistic, but go back and check all your connections.
Take the cover off again and make sure that the main circuit board on top is pressed on tightly in the area over the right-hand back side because there are two connectors there. Also, there are several other connectors that should be checked--two on the left side, and one just underneath the left side. Those are all the kind where several wires enter a small, hard, plastic rectangle that then plugs into a little socket.

I have the same model projector, but my blue lcd panel is burned out. The other solution I can offer is for me to buy yours from you and use it for parts in mine. Good luck.

SHARP XR-10X PROJECTOR LAMP


Lamps are easily replaced by the user. Get a new one and pull out your instruction book to replace. Make sure you clean your air filter regularly to give longer lamp life. There is no way for you to "fix" the lamp module without replacement.

Blue patch on left side of screen


I had the same problem with my Hitachi PJTX100. I discovered that there was considerable dust build-up inside the unit, causing insufficient venting of heat which then damaged the color prism/filter. It was close enough in time to the warranty for Hitachi to cover parts replacement (approximately $1,600). Since the repair, the blue patch is gone. I also regularly vacuum not only the outer cover but also the inner air filter that easily snaps on and off.

Yellow area in the projected image


Hello Media Man,

Looks like your projector has done it. Thats acommon trouble to ageing polirising lens, usually the blue. less blue, the green and red make up the yellowish image on the screen. The blue is bombarded with tremendous heat from the lamp and it fade and wash out. If its free, its worth replacing. Get quote for the poliriser; 2 pieces each color.
Good Luck.
