i was having an intermittent problem with my hl5687w dlp. for a few months now, sometimes it would not turn on, it would make a low buzzing noise for a few seconds, then all 3 lights would blink,and it shut down. but in like ten minutes it would go on. finally, one day it was just done, and would not go on. i figured the lamp, i asked around and everyone agreed. i even went to samsungs website and chatted with a tech who said the same thing. i replaced the lamp, and tried it. it tried to go on, i hear the click from the ballast, but no picture or sound. from the back, the bulb lights, but no pic. then after about 20 seconds, all 3 lights blink and it shuts down...samsung tech says i have the wrong bulb, but they are identical, and run the same wattage,and it is a Phillips bulb. ballast? board? wrong bulb? please help, im working with a 37 inch lcd on a tv tray..it sucks

That buzzing sound is a symptom of a bad ballast, buzzing like electricity right or somekind of mechanical, the when you mentioned that the bulb lights?????? do you see the bulb is on from the back or the sides of the tv??? because if the lamp is on and you dont have no picture it could be the light engine, hope this info can help you.

i do see the lamp light up, no picture, then it shuts down after about 20 seconds. is there a diagnostic to figure if its the light engine?
