You have bad capacitors in the power supply that took out the regulator, or the ballast circuit is defective. Not really a repair for the novice. Good Luck

This happened to me also. It had to be taken apart. The audio connector on the motherboard had come lose. Hope this helps.

SOURCE: Plasma TV buzzing

If the adjustments on the power board are correct and if you are not at high altitude, the plasma display panel is defective. If the set is off warranty, it is not cost effective to replace the display panel. If it is off warranty, you should give the manufacturers Customer Relations a call. The phone number is usually right on the back of the tv. The manufacturer of the tv might make a warranty concession if they are concerned about their brand reputation. Some manufacturers find it less expensive to just switch brand names rather than make good on defective products. If all else fails, you might get some money back by selling the circuit boards on eBay.

SOURCE: 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:

First. The whirring or buzzing sound you hear is the Color Wheel and it needs to be replaced. Second, since I do not know when and if the original lamp has been replaced it is a good idea to replaced the lamp. The bad Color Wheel is the one causing the set to shut down.

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.

We have a constant buzzing/whining noise when the TV is on.


Is it a whuring or buzzing sound? When color wheels go bad they can make a lot of mechanical nose, cooling fans can do the same but they do not spin as fast as a color wheel does

Have a Toshiba 42hm66 and it has started to make a humming/buzzing noise. At first it would make the noise for a few minutes and then quit...now it does it the whole time the tv is on. Any ideas?


Sounds like a fan getting cought on some dust inside you might want to have this serviced if you do not know how to clean it.

The humming would be a fan the buzzing would be the fan getting stuck!!
