I turned my TV off. Later I turned it back on and I heard a pop, then this awful grinding noise. I changed out the bulb about a year and a half ago. Picture is still quite bright. I pulled the back off the TV and cannot isolate where the buzzing/grinding noise is coming from. I left the TV on for a while hoping it would work out. I've noticed when the grinding noise slows down, the picture wavers.

The lamp can cause a dark picture if it is defective. There is an access door to the lamp. Take the lamp out and inspect it. Especially at the bottom of the center stem where you may see a bubbling of the glass. If so it is bad for sure. Other problem could be in the main board. For good price on lamp with housing go to pureglare.com and enter the model number.

Hi,
There is a very good chance that we have a bad lamp here again. Which is about the best case for you.
I think the first thing we should do here is take it out and inspect
it. We might find that it is shattered and know without a doubt that it
needs to be replaced.
Also if you don't know about the
lamps in these sets here is some information: These lamps are a
"consumer replaceable item" meaning they are made for you to change.
This is similar to changing a light bulb in a lamp but allot more
expensive and a little more difficult. These lamps last on average
anywhere from 1 to 3 years before they need to be changed. They also
burn out based upon the number of hours the tv is on and the number of
times the tv is turned on in its life. The more you watch the tv the
faster the lamp will burn out, and the more you turn the tv on and off
the faster it will burn out. There is really no way to prolong the life
of a lamp other than not watch the tv, so most people don't worry about
it to much and just expect for this to happen ever couple of years.
Let me know,so that we could proceed.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
