It sounds like the polarizer filters are starting to ware due to heat build up, if you remove the lid and the main booard, there is a white plastic mesh cover over the lcd panels, you can remove this and adjust the polarizers for the red, green and blue lcds to adjust the black level, there are 3 hex bolts holding a plastic frames which in turn hold the pre polarizer filters, buy slightly loosening the bolt you can slide the plastic frames left or right to adjust the levels, buy you should mark the position before you start. this may not solve the problem but may help to improve it, unfortunately these projectors require special software to make electrical adjustments which is hard to get hold of.

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.

Yellow tint


Hello. Here's the visual key to remember about projectors--LCD panels show their colors like this: RED lcd panel displays cyan onscreen(baby blue); GREEN lcd displays purple; BLUE lcd displays yellow. ( You now know where the displayed dust is!) The problem is most likely a burned blue lcd or polarizer filter in front of the blue lcd panel. This occurs when the dust filter isn't cleaned regularly or properly and heat builds up--yes, enough to "cook" the lcd panel or actually cause a burn to develop on the polarizer. The polarizer is just like a lens in a pair of good sunglasses. It is a small, extremely thin, pane of glass with polarizer material glued onto one side. When burned, it causes a "shadow" effect--that enhances the display of that particular color--in this case, yellow.--Hope I was of assistance!---Rick

I have a hitachi-ultravision digital tv and there is several areas of blue on the screen edges and also a blue area in middle of the screen..


I hate to tell you this but what is called a filter 'Analyzer or Polarizer that is positioned before the Blue's LCD panel is going bad or has a great amount of dust build up on it.
A Good TV Service with experience on these types of LCD TV's should be able to tell you what the cost of repair is.
Blessing,

Dell 2400 MP DPL Projector projects a yellow tinted image.


Clean any external dust filters or air openings in the unit.If you don't want to remove the filters, you can simply use a vacuum cleaner hose to suction away the dust from the filter element--same effect anyway. The unit probably does indeed need a thorough cleaning.
The yellow effect is most probably a burned BLUE polarizer filter located behind the blue LCD panel. (Color key--Purple onscreen=green lcd, baby blue onscreen=red lcd, and yellow onscreen=blue lcd). That's how you can tell which lcd has dust on it! Usually, the green lcd has the most free area around it and collects the most visible dust. (large purple specs) The polarizer filters can get burned due to excessive heat (not keeping proper ventilation). Of course, it might be the blue LCD panel which is failing prematurely due to heat build-up over time. The polarizer filter isn't that expensive if it can be replaced, however, the actual lcd panel IS.---Rick

Projection has yellow tint


From your description, it sounds like a problem with the blue color. Green LCD=purple onscreen, Red=cyan(baby blue) onscreen, Blue LCD=yellow onscreen. It could be a lot of dust on the blue lcd panel, or worse, might be a burned polarizer filter behind the lcd panel due to excessive heat. If you can focus on the yellow and its tons of yellow specs, its dust. A burned filter however, must be replaced. A technician trained in projectors will have to do it. The filter material is glued to a thin glass panel and is replaced as a single filter. It's a very involved repair.

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 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 !
