A little earlier, I posted because I couldn't get my 300u to turn on. I just got it. Well, I had it mounted with monkey_man's $20 diy mount. I took it down, and from something my wife read in the manual, I just opened the door to the bulb, re-closed it, and walla, it turned on. Well, I re-mounted it again and things "seemed" to be going well. It turned on, but, I couldn't get my dvd player to play through the component cables (the composite works), and, the fan started sounding horrible (really noisey). Has anyone else had this problem? Any advice as to what I could do?
