You need to check:
the Vga cables if the image shown is that from a computer
firstly check if the Panasonic logo comes ok in the beginning
if ok then try connecting a laptop directly thru a short patch cable to the computer port of the projector[i am assuming that the projector has been installed to the ceiling]
if this works ok , then the projector is fine!
you need to figure out the problem with the vga cabling and switchers if any of them are used!

sounds like bad cables, or wrong setting on projector you may have it set to compoent instead of composite,, you don't tell how you are hooking it up. (what type of cables you are using)

may i know now what is the age of your projector. have you done replacing the lamp of the unit before.
Lamp life varies by manufacturer and projector type.
Lamp life also depends on the projector's environment: air flow, clean
air, and also on the level of usage. Check the user's manual or
specification pages for your projector to determine the exact lamp
life.

It sounds like the projection lamp is beginning to show its age. How many hours of use does the unit have on the bulb? The bulb are typically rated for about 800-1600 hours of use before they go bad. The bluish image on the screen image is a typical tell-tale sign that the bulb is going to need replacing.
Most of your better projection units will have an internal time counter of the bulb life from the time the unit is first used or when a bulb is replaced. Check to see if your unit has this feature, if so it will show you on the screen display what is the total number of hours on the bulb and the estimated remaining hours of life.
Be aware that the replacement bulbs are NOT cheap and usually will cost you several hundred dollars, I have seen bulbs for professional projection units used for large convention/presentations have bulbs costing as much as $500.00 USD.
One other last thing to check is to clean the lens of the unit both inside and outside. To clean the inside, you will need to remove the bulb (be sure to wear a rubber glove as the oils from your skin will cause the lamp to blow, (causes a hot spot)). Then using a cleaning wipe, just as one used for cleaning microscopes or glasses, wipe the lenses. The discoloration might also being caused by dirt and oils on the lenses.
I hope this shed some light on your church's projection problem.
Testimonial: "I was hoping that it would not be a bulb issue. I do not know at this point how much age is on the bulbs, but I am going to check tomorrow. "

here are some probable causes..
This appears to be an older model (over 5 years old) and LCD projectors turn yellow with age. It's just what they do
However, if you are projecting a computer signal or a component signal, a short in the blue signal of the cable can cast yellow hues over your image. The hue will cover the entire image as if you are viewing the image "through rose (or in this case, lemon) colored glasses" so to speak. That's an easy fix.
Harder fixes: the blue LCD panel is weaking and/or gone bad.
If you have a round yellowish spot in the middle of your screen, the diffuser has been overheated and is "burnt".

I have the exact same issue with my projector and was wondering if anybody has an idea what the problem/solution could be? Have checked all internal connections, wiring, etc. but nothing is physically wrong with it. Powers on and off with no issues; bulb is working but no light out of the lens. Please help!
