    Same issue here...it seems that the yellow blog changes somewhat between each power off and power on. Prior to this issue, we had an issue where the whole screen had a strong yellow tint.

Yellowish colorization on center of displays is not a prizm issue. It is generally a need of cleaning factor. Even with the filters clean, the LCD's can and acquire heavy dust build up on the panels. This is not limited only to the LCD's it also applies to the polarizers and spectrum filters. Your unit most likely requires deep lens and panel cleaning. This is done by trained professionals, as they can be permanently damaged if the proper tools are not used.

Depending on what it is if it looke like a scorch mark the it is not the Optical Engine (prism) it is more likely to be the polerising filter most are quite esly changed and would cost about £15 ($30) for parts and about twice that to get them fitted at a service center, if it is pixel dots then it is a LCD replacement and not worth doing.

Your blue device is dying, this problem is as old as lcd projectors. I would suggest replaceing with a dlp product. Lcd's are organic and can't handle the heat and the blue is the first to go. Average about 3-4000 hours..

Projector is working but intensity problem,, display is not good


Have you changed the brightness setting or put the projector into eco mode. ?

Also see what mode your dvd player is in (same on projector) they can have film modes which reduce the brightness.

The XL8U will tell you when the lamp needs replacement. There is a yellow box that will appear telling you so. The lamp is easy to replace, the model number is VLT-XL8LP.

Yellow spot


the problem is in the light path starting with the blue input polarizer then the blue lcd hopefully its just the input polarizer. worst case you will have to replace the LCD block witch is expensive to do. the polarizer ia a speacialy tinted glass designed to help with the LCD's temp.

Lamp Meter: Where do I look for it?


On the Control Panel, if you press the up-arrow, enter, and down-arrow buttons at the same time you get the usage screen. The hard part is selecting the three buttons at the same time. It takes me multiple tries to get the combination correctly.

Yellow middle, Blue Exterior


Hi Druaga

This is a Blue LCD Polarizer that will have to be replaced if the spot shows yellow.

You will find that this will only get worse as time goes by.

Hi terry2421

No this is not the bulb. You will have to get the Mainboard repaired at a service provider. Losing signal and a discolouration showing up is a clear indication of a faulty Mainboard.

Get a quote first , because some service providers overcharge on these sort of repairs. The most you should pay is $150.
