Toshiba 56HM195 56 in HD DLP Loud Buzzing and color distortion

Our TV makes a loud buzzing noise which gets louder the longer it is on, and there is a significant color distortion, Bright Greens, we have tried to reset the color selection on the menu, we also just replaced the bulb no more than a month ago, any ideas what is causing the noise and color distortion now?

    Same loud noise/buzzing problem. Call Support at Toshiba, they directed to local shop. Local shop estimates about $1,000. Color Wheel in light engine was suggested by Sears where we purchased it only two years ago. Is cheap Color wheel availble ? Is it fairly easy to replace?

If the sound, sounds more like a Hum with some vibration chances are the Cooling fan located behind the lamp is going bad, about $20 to repair, if its a high pitch hum most likely the Color Wheel and if thats the case about $30.
Good luck, my fan just went bad now seeing green dots everywhere, so debating on just junking it out or fixing it, with winter coming on might just breakdown and buy LCD and say the heck with DLP from now on.
Good luck to you..

I have a loud buzzing noise on my Toshiba DLP 46" projection TV. It is not the fan, it works fine. In fact the TV works great and has a good picture. The buzzing used to go away after awhile. Now it...


In some cases the buzz is external. The vibration of the unit may just cause a tray, flat surface, or other surrounding attachments to rattle and buzz. Look for anything that may be loose or laying on or about the TV.
