Hear a whirling sound within a few seconds of tv image coming up - continues while watching and winds down when the set is turned off (fan?)


It could be the color wheel in the TV that you are hearing. There is a color wheel that spins in order for you TV to display colors and if it is struggling to stay at the right speed, it could cause the sound that you are hearing.

The fans also make some sound as when they spin and will remain on for a few minutes after the TV is turned off in order to cool the TV.

No display or sound on Mitsubishi WD-52725


This is a DLP They have issues with the color wheel, the winding sound could be from this color wheel. If it stops spinning it will cause the tv to shut down. DLP is a mechanical display process. If you are handy and understand electronics you could replace this yourself. If not i would let a tech handle it.

Cooling fan is loud . I'm going to replace the lamp in the unit because all 3 lamps are blinking on the front panel. Unit shuts down but I'm wondering if there is a seperate cooling fan in the back of the...


That's probably the Color Wheel you are hearing. When you turn the set on the color wheel has to run, one of the several things that has to happen for the set to come on. The color wheel sends a signal back to the control circuit to tell it it's running. If these sets fail to light the lamp they will shut off and try again, that's why you hear the color wheel start then wind down then start again. The set should try three times before it decides it's not going to be able to turn on.

One way you can tell the difference in the fan sound and color wheel sound is if you can get the set on, let it run for a little while so it gets warm, then when you turn it off the color wheel will start winding down but the fans will continue to run for a minute or two.
