Have an old samsung hlr5067w, started buzzing horribly last night, I was in other room with my recording setup. Wife tells me it just got real loud. I did not get to analyze before she shut off. She said the Pic was on, but twitching and color was screwy. When I went in, she had turned off and pulled plug. (Oy) I plugged in and it hums loudly, seems to try to start, nothing on screen, lamp light on front flashes, cycles through loud fan for a few minutes, shuts off, tries again, then shuts off and all three lights on front flash. Any help? I can replace Color Wheel or Lamp, but don't know how to tell what the problem is for sure first. I just joined, my first post. I am also just creating my home studio for VO work and am investing my money there, so would prefer to fix & make due for now if it is feasible.
