DLP buzzibg (humming)

[stufl]

I have a samsung DLP HLR5067W and replaced a broken colorwheel. I am now experiencing a "buzz" which disappears when I mute the sound. Is there something I can reset in the service menu, or is this a ballast or lamp issue?

That sounds like your speakers are starting to kick the bucket. The ballast is unaffected buy the remote since it’s the board that regulates power to the lamp.
Try increasing the volume on the tv, if the buzzing gets louder, then its definitely the speakers.
Good luck.
