While changing the bulb on my LCD TV I noticed that behind the bulb (I assume the LCD chip) has dust or ? on the face. Can I clean that before reinstalling the bulb and if so how?
Use only a lens cloth and some dust is normal.
I noted the haze or ? on the optical Block when replacing the bulb. With a new Phillips bulb the TV now works great. From what I have read online I guess I will eventually have to replace the optical block. I understand their are remanufactured untis out there as this TV is out of warranty. Thanks to all who responded.

Yes, it's possible, but it's more art than science and there is a risk of making the problem worse. If they are only visible from very close, do you really want to take the risk. Also, if your TV is still under warranty, any home repair will most likely invalidate your warranty.
There are some good video guides to cleaning your LCD and repairing scratches on YouTube:

Personally, I use a large pure-bristle (not nylon!) paintbrush for removing heavy dust before cleaning as it doesn't drag potentially abrasive dust particles across the screen.
It's unlikely the scratched screen is covered by the TV warranty, but if it's really bad you might consider making a claim under your contents insurance - if you have accidental damage cover.
Hope this helps.

The optics block has failed and it will have to be replaced. Contact Sony for an auth. service center in your area as the optics block in this unit has a 2 year mnfg. warranty.
