My projector sony vpl cs6 projects yellow

Bit of a common problem with Sony projectors of the era that they often had problems with fading and/or cracking of one or more the LCD panels - especially the blue ones for some reason, leading to the type of problem you are experiencing. No point in swapping components either as they will both have similar faults - although replacing an LCD in a video projector is almost impossible without the manufacturers jigs to mechanically align them afterwards anyway...

In the menus there should be an "image" adjustment option, it could also be related to the "sync" rate. Try different settings. You may also need to adjust the resolution you're sending to the projector from your computer.

Connect the power cord and turn on the projector.
When it's in standby mode, press the following keys on the remote in this order for less than 5 seconds each.
RESET
left arrow
right arrow
enter

What's the problem

It is possible that there can be few reasons for the fault siad:
1.the lamp can be faulty
2. the filter can be clogged.
3. the lens cap trigger switch can be faulty and staying on
4.The power supply can be faulty, not delivering the power but shuts off.
5,the main processor board can be faulty witth errors.
It might need board swapping to confirm.

does the "lamp/cover"-led light up? i had the same thing happening, the lamp either broke or is about to break and the projektor won't turn it on again to protect itself. if its very urgent, open the projector pull the lamp out and put it in again, it might work for 1 or 2 more times, but it is very likely to explode (usually not breaking the projector but for sure not good for it).

good luck!

You have a bad lcd, you would probabaly have some blue lite leakage also. Any lcd projector should not be left on the same image for long periods, it wears out the pixels that control the lite thru. The blue lcd is usually the culprit.

There may be a dust fleck on one of the LCD screens inside your projector. I had a similar problem and managed to clean it. But it requires you to dissassemble the entire projector !!!. If you are not technical, don't do this yourself. !!!

Hi Tim

I've seen this many times. Only way to get rid of it is to replace the Mainboard.

This will get worse as time goes by.
