Question

My television has audio and no picture it went out when i was watching it the tint of the picture got a pink tone to it and then went out shut it down by unplugging it waited and started it back up it was working and then it started to deteriorate mostly static/fuzzy picture. restarted and it worked for an hour or so. Next mornig no picture just sound I hear some whining louder than before but it doesn't seem to be as loud as most people describe when their color whells go bad. Can they make just a little noise? bulb lights up initially but I hear the whine and then the bulb shuts down. I guessed the colorwheel but I am not sure. What do u think? I would hate to take it to a tech if it is just a color wheel i had the old one out spun it a little and it spun but the bearing seemed a little rough so replacing it isn't a problem. if it is more complicated than that i'll take it to the tech.
