Blueish tint on picture

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.

Re: Blueish tint on picture

No... 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 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.

Blue tint projector

Hi Bear,

This is likely an issue with the polarizing plates, which need to be calibrated or replaced. This is not something that can be done by the average user. If your problem persists, please send us a message: Projector Repair Bulb Replacement

Lense hours

Hello muhammad
Projector's lamp life is said to be, not with the lens life. Lens is made up of glass. But lamp will go weak. the life of lame will depend on how much time the projectior have used. Normal life of Panasonic projector bulb spans between [1800 to 2000] continous use. It means, if we take the low life span of the bulb as 1800 Hours [1800/24=75 Continous days]. If we use it for 4 hours a day, the bulb may last for [1800/4=450 days ie 1 Year and 85 days] OK.

Our PJ862 we use for church has developed a blueish tint to the display. It is pretty harsh and looks really dark and blue. Any solutions? Would changing the bulb help?

Since this is a 3LCD type system, I believe the blue organic filter polarizer glass plate that filters the blue light beam before it enters the blue LCD panel is burnt due to old age and causing the picture to go blue.
You can confirm this if you safey remove the cover and check the optics.

Is there any way to check the bulb life on a Sanyo PLC-XU30 projector? I know some projectors have an option on the menu screen which lets you know how long the bulb has left. Its just that i bought it off...

on my XU 55 the trick to read the lamp hours is to press and hold down the power button in about 20 seconds when the projector is turned on. there will come a window in the upper left corner that tells about total hours and lamp hours. the window will disappear quite fast, so one might need to do it twice.

What would cause a Christie to shut off after 60 secs?

On my Vivid Lite the projector will shut off when the lamp hour count reaches expected lamp life. It will restart only long enough to read the hour meter again then shut it's self off again. You can manually reset the hour meter to continue using the same lamp.

Hp VP121 needs new bulb?

Hi there

Take out the lamp and check for any marks on the inside ( shaft ) of the lamp. If there is marks or discolouration on it then you can be 100% sure it is the lamp.

My picture brightness is uneven - there is a persistant bright field on my screen.

I have the exact same problem with my AE700. It a started about the same time, around 2500 hours for me. I lived with it untill I could afford a new bulb which arrived yesterday. The old bulb was still working at a 3603 hours when I installed the new one. But the new bulb didn't fix the problem for me either. I may try to take it apart this weekend and give it a good cleaning. Andy
