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.

I need the service manual of '29mcz5m toshiba tv'


I went to the Toshiba web site (www.tacp.toshiba.com/customersupport/) and entered the model number you gave. It said no such model exists. If you can, please double check that number & click on the link I gave. You can download a PDA version of your service manual & have a hard copy. Hope this helped, kwmjo. Good luck with you repair.

Problem with Toshiba DLP Projection TV Model #52HM84


It is possible the lamps may be defective or that they may be the wrong replacement for this model, as it may have a different wattage setup with the ballast. If you want to try to order the TB25 lamp from a different vendor, you can order the original Toshiba replacement lamp for this model (52HM84) from a major Toshiba parts distributor at the link below:

Buzzing after 1 hour


Is the buzzing coming from the back of the TV, staying loud even when the volume is turned all the way down, or is it coming from the speakers?
