Question about Televison & Video
My Mitsubishi WD-57731 won't turn on. It'll make a whinning noise and crackling noise. I checked lamp and it doesn't look burned out. After TV fails to turn on the TV will not respond to any buttons unless you reset it. There's no yellow or red light.
It takes a trained eye to see failure in the bulb. I susppect the lamo is gone. You hear the color wheel spin up and the lamp tring to arc. (crackling sound)

Sounds like the repair guy sold you a generic or remanufactured bulb. There is no break in time on these parts, more like a break down time....it will only get dimmer with time. If you're comfortable doing so, pull the bulb and inspect it. Look for a brand name, if it says philips or osram you're fine. If you don't see either of those, then this ballast may not run quite as hot as the last. If the dimming effect is something that really bothers you, call the repair man and tell him. Also look at your work order reciept, does it specify what kind of bulb was used as a replacement?
