Check the power supply & fuse and make sure to vacuum out the dust.

In this case it seems you may have an issue with your ballast. Either it's going out or barely starting. I recommend you replace it

well sorry but this happens to mine to like every 2 years so you need to get a new bulb

Most likely part is the Color Wheel, most people describe it as a grinding noise.

On my samsung hlr6167 dlp,it was the signs of a lamp going bad/defective. Replaced the lamp and the problem is gone now.

You have one of the dreaded N series that is full of problems.
Even if you are out of warranty, they have been known to work with you.

i have found the lamp will cause sound no picture but if the picture freezes could be dmd bd or digital bd going bad

DMD bad, not cheap to fix and part is hard to find. Expect to pay $600
