I have the Samsung HLP4663W DLP. It has been making a whirring noise, so loudly that I'd have to increase the volume to hear the tv. Yesterday it wouldn't turn on at all. The lamp light was blinking so I went online, ordered a lamp, and low and behold it arrived today. I replaced the lamp (and housing) and now the stand-by/temp and lamp lights are flashing and the set wont turn on. Any ideas?
