Re: blue on one side
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:
- If you need clarification, ask it in the comment box above.
- Better answers use proper spelling and grammar.
- Provide details, support with references or personal experience.

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.
( 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.
Hi, please try to replace the cable, try another input source and reseat or replace the bulb . If issue still present upon doing those steps you may need to call epson tech. support at 562-276-1300 so that they can verify whether your projector is under warranty or not and give some great option regarding your projector.
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.
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
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.
