I own a Samsung HL-R5067W 50'' DLP. Set is about 3 years old. Recently I heard a loud pop while viewing, picture distorted, but never went blank. I turned set off. When turned on again a loud whining noise (sounds like a bad fan) occurred and lamp would not aluminate. Green lamp light began to blink on power button and about 15 seconds later the set made the electronic sound it would usually make under working conditions (as if the set is trying to turn on, but no lamp light). Green lamp light would blink for about 30 seconds then red standby/temp will light up (constant not blinking). This process re-occurs about three times then all three lights (Green Lamp Light, Red Timer Light, and Red Standby/Temp Light) blink. Manual suggested this may be a bad lamp so I replaced. This has not resolved the issue. Same exact problem exists. New lamp has never aluminated.
