I have a new bulb, with under 300 hours of lamp life, recently (last 100 hours) a blueish tint is showing up more vividly throughout the picture... Looks bad with dark images. Anyway, I'm trying to determine if this is a problem with my projector itself or if I got a bad replacement bulb through B&H photo.
I've ruled out a cable... I get the same results using HDMI, VGA and Component cables. Any help would be appreciated.
lcp panels will look different when going bad !
this is the polarization filter, most of the time the one BEFORE the lcd panel (blue in this case).
these should be cheap but are not easy to get...so you might pay quite a lot.
you can also buy polarization filter sheets and cut them to size.
keep in mind to check for the right orientation !

Re: Blueish tint on picture
Most likely not a bulb problem (substitute a known good bulb if you have one to be sure). more likely is a bad LCD panel inside the projector. the light is split into 3 beams which go through 3 LCD panels (red, green, and blue) which produce the picture. the blue panel could be going bad.

Your blue picture tube is failing. Invest in a new TV. "If" you can find a new set of tubes(you have to replace all 3 red blue and green) they are around $800-1000. Not cost effective. Run the TV into the ground if you want to wait but do not invest any repair money in my opinion.
Hello, it sounds like the lamp has gone bad, it's gone interminent to the point its like a flasher in your cars blinker system. If you remove it, you might see if it's discolored to a blueish tint instead of a shiny silver mirror finish. On those with the small lamp it can be harder to see. the lamp number is XL-2400.....tks
You're either using old/expired film, or taking photos during dusk. Color film is balanced for daylight photography. Using it under conditions other than that will result in varying color casts on the resulting images.
Fluorescent lighting: Greenish
Indoor bulbs: Reddish/orange
Outdoor at night/dusk: Blueish/purpla
Ourdoor at dawn: Pink/blue
Or, you may have just gotten bad print work done. Try a different lab.
pepsi_2_cola, If after reseating the vga plug to vga connector 3-5 times and the problem still persists, you will need to see about having the unit refurbished with new "switch-mode-power-supply"/ "inverter board" and possibly new "cold-cathode-fluorescent-lamps" installed. visit YOUTUBE before doing the refurb thing! Search and view vids on "lcd monitor disassembly" , "lcd monitor repair" the longer ones are more imformative. then get back here with what you have learned about how lcd monitors fail with age and amount of total "ON" hours of use. please state the age of monitor next time! a gateway 1975 could be 4-6 years old! It could also be time for a new one! You DO KNOW that those "cold-cathode-fluorescent-lamps" don't last forever!!!!! 12fixlouie If this was of any help please rat this response on fixya.
