I have changed the bulb on my Sony VPL-HS50 video projector and the image is now in black and white. I folloewd the instructions in the manual word for word. The bulb is a Sony genuine part

It must be a problem with electric connection. you should check whether it is OK or not. If it is okay, read instruction manual.

Your bulb is going out. replace the bulb and you should be fine.
Just remember to set back to defualt settings before your change the bulb out and make sure your give the bulb time to pre-heat before you turn the project all the way on.

If this projector is an LCD (liquid crystal display), your LCD probably gone.This usually happens after a period of time with an LCD projector.Try cleaning the LCD or take it to your Sony dealer. yours faithfully Zkhan

These instructions are for a Sony Cineza VPL HS3, but may be the same for the HS3.
1st thing to check - is the cover properly/completely closed - this can stop the projector from working.
Connect the power and set the projector to standby mode.
Press these buttons on the remote control in this order, for less than 5 seconds each.
Reset - Left Arrow - Right Arrow - Enter

This is required, to reset the lamp timer.

Also, something I found interesting from the internet - lamp life isn't when the bulb dies, but when a bulb has lost 10% of its brightness - so you might well be able to reset the timer and get much more use from the bulb - the image just wont be as bright.

Thank you.

I also have the same problem -- the fix is to replace the optical block ( Internal lamp engine ) which is a $1,100 part. I just purchased a used projector for half the price of the part.
