Sony VPL PX40 Multimedia Projector Questions & Answers
Noticed a yellow hue in the centre of the image projected by BOTH of my second-hand Sony VPL PX40's.
Bit of a common problem with Sony projectors of the era that they often had problems with fading and/or cracking of one or more the LCD panels - especially the blue ones for some reason, leading to the type of problem you are experiencing. No point in swapping components either as they will both have similar faults - although replacing an LCD in a video projector is almost impossible without the manufacturers jigs to mechanically align them afterwards anyway...
How do I take apart a px40 projector?
1,remove the screws on the back. (only 1-2 screws)
2,force the cover(white) from the back
any questions, feel free to ask me
have a nice day!

How to fix yellow hue center bottom of
Most often color distortion is due to the bulb wearing out. Projector bulbs often fade or distort colors before they actually burn out. The other thing you can try is to reset the projector to it's factory settings, which sometimes fixes color issues. It's usually an option in the "settings" area of the menu.
Blue glare
HI there
This might only be a dusty lens on the inside. But it could also be a faulty Mainboard or LCD's.
Take it to a Service Centre and ask them to check it out for you. They normally quote first and then repair if you give them a go-ahead , you've got nothing to lose.
Bulb Reset issue
I had the same problem and called Sony, they just said to keep trying what the manual says to do, but make sure the unit is in standby mode. I tried in powered mode and in standby mode many times and it did not work. Then I tried again the next day when the unit had been in standby mode for an extended time period. I hit the four buttons like the manual said, all four in quick succession. I also tried the four buttons in many different sequences from what the manual said. When I powered back up the lamp timer was set to zero, finally! I think having the unit in standby for an extended time was the key. The Sony rep really emphasized the need for the unit to be in standby.
