I just changed out my lamp on HLP4663w because the pic went out and had the whole lights flashing deal on the front. Well that didn’t do anything but now it it’s vibrating when tries to start up and I can hear the ballast clicking like its working. I made sure the lamps seated good and cleaned the dust out too still no picture just sound and vibration til it shuts back down. None of the other postings really said anything completly like this problem and I know there’s alot of us out there with these problems so any ideas would be greatly appreciated!
