Here is what has happened.
54% of lamp life used and working great...then hear a pop. Similar to the pop you here when a high pressure bulb goes bad, but not as loud. Then the picture went darker, not a complete loss.
I turned it off and then restarted. It would not turn on after about 45 sec, green lamp light still flashing, so I unplugged, changed the bulb with a new spare that I had, turned it on and now color banding. Colors are wrong and boxy.
Here is the kicker, when I turn it one and the bulb starts up, for the first 5 seconds the picture is perfect...followed by a flicker then the screen freezes for about 5 seconds then the color is all wrong and it gets slightly dimmer.
I put the old bulb back in and tried to start it but after 90 sec or so it gave solid red replace lamp bulb. I have also reset the lamp timer and have tried the digital impute and analog and they all behave the same.
Please help. Thank you all so much.
