Device level repair of the blue lcd device. Not a user repair. The blue device has or is failing. Happens about 3-4000 hours of projector life. Its called color decay. Suggest replacing with a dlp brand product.

The image on screen is almost a dirty yellow colour and not sharp at all. Also where do I purchase new filters from?


Hi,
A yellowing image, especially if it's circular in shape indicates the BLUE LCD polarizer is burned from overheating or just a lot of hours on it & it needs to be replaced to make the yellow go away. You can purchase a new filter from hundreds of online retailers. Just do a search on Google for "NEC VT595 Filter"
REPAIRS:
If you're interested I do replace the polarizer filter panels. I have parts in stock for the NEC VT595. The repair quote is $50 & if you have it repaired the $50 is put toward the repair. The repair will include cleaning all the LCD panels, filters, lenses, etc. on the inside which will bring back the original sharp picture again. If you like you can email me at prmhelp@earthlink.net for more information on having it repaired.
Thank You,
Jim Peters

Sharp notevision xgnv6xu oval yellow spot


I have a similar issue with yellow pattern on the left and top right of my screen. Took it apart and found the blue lcd had damage that matched the yellow area that was projected. I thought it was the lens but it was the blue lcd .It has gone bad and no replacement. Are you interested in selling the bulb or the whole projector? I have since purchased another projector and am keeping the bad one for spare parts. Hope this helps..Ben

OVAL SPOT IN PICTURE


LCD 101, your blue device is dying in the projector. Very common problem. The blue device cant handle the heat and allowing the other colors to come thru. I suggest replacing with a dlp brand product.

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 there

Is there any on screen prompting ?

If not , open up the lamp door at the bottom and take out the lamp. Check on the lamp's shaft for any irregularity ( i.e. vein like looking black marks or bubbles or a white spot , also check that the fillament on the inside is not broken.)

If you spot anything I listed up here , your lamp will need replacement.

If you cannot see any irregularity , check when the unit shuts down which of the LED's on the unit flashes.

It will either be your lamp or the Ballast ( lamp's powersupply ) that is faulty and will need replacement.

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
