If it is a single line, one element burned out on the LCD. If it is a wide band, the LCD or the element driver is defective.

Hi Ron usually power down issues are caused by faulty power supplies especially if the projector looses power completely however the logic board could be protecting itself if it detects a fault such as a fan not working either way it is not recommended that you try to fix it yourself unless you know what you are doing, but it may be worth removing the cover and checking that the fans are working and connected properly, occasionally the lamp can be at fault especially if it has been used for many hours if the projector tries to power up and you see light through the lens and then it looses power its probably the psu at fault, if it powers up then goes into standby of fault then its most likely a logic issue. I hope this helps Regards Ant

Does your projector take lot of time to shut down? May be because it take a lot of time to cool down.
The main culprit would be dust, blocking the air vents/air filters. Use a 1/4 inch paint brush to clean them.

If you are talking about the actual image that is coming from a laptop being yellow instead of white, then this is caused usually by a bad signal cable running between the computer and the projector.
To be more specific: All colours in a projector get made up in some way between red, green and blue. White is all of these colours at maximum, yellow is made by red and green at maximum but no blue. If your image is Yellow when it should be white, then the blue signal information is not reaching the projector. This can also happen within the projector or computer itself but is less likely. If your using a VGA cable (15 pin cable) then blue is run through pins 3 & 7 (positive and negative respectively), see if your cable is either missing these pins on either end or if they are bent, although it's more than likely within the cable itself. You can test this theory easily by trying to put something blue on screen, if the blue signal isn't getting through then it'll appear black.
If changing the cable doesn't solve the problem try testing the computer by trying to use a different one, and test the projector by plugging in a monitor or another projector.

If you are getting a yellow screen without sending signal and just trying to get the "no signal" or "no input" screen white, then this won't be the case.

Hi,

Welcome to Fixya. If you need the audio of your presentation please check the connection if it is correct please refer to page 14 of the instruction manual. Please make sure that the cable from your computer is connected to the green port. if it is connected to the front port of the computer please try the port at the back. If you have spare cable it would be better to check if the cable is not working.

If you have questions please let me know. Thanks for using Fixya.

Sounds like you're missing the proper drivers. Download the latest drivers from the manufacturer's website and you'll be set to go.

This problem and the error beep codes indicate a lamp that needs to be replaced. The correct part number for the lamp is VT85LP. Basically the lamps are rated with a life expectancy of 2000 hours. At the 2001 lamp hour (3001 in eco-mode) the LCD projector will power on, but not display an image, due to the indicator requesting the lamp be replaced and the lamp hours reset (hold the help button on the remote for 10 seconds when powering it on).
