SOURCE: Toshiba 46HM95 Buzzing

I have the same thing, mine is the cooling fan for the lamp. If the sound continues for a short time after you turn off the TV then this is the most likely cause as the cooling fan will continue to run for a short time to cool off the bulb. I have looked into replacing mine, the part runs around $50 but I can't say yet how easy it is to replace yet.

TV turns on then cutts off


that buzzing is the high end power trying to turn the lamp on.... the electrical current and shock is what turn your lamp on your tv which is what the buzzing is dont worry thats normal...however your solution is buy a new lamp for your tv but make sure its the right serial number for lamp u cant just buy any lamp. best place to buy one ebay.... as in the lamp still trying to light up its only because the electrical current going into the lamp and then cutting off causing the red light on your tv....so other words all it is is the lamp... CAUTION!!!! those lamps get up to 400 degrees unplug tv to ensure no electrical current.... hope i helped.... JACOB WINKLER

Turn on TV hear a buzzing and then the TV cycles off and on again


Hi,If it seems you are experimenting a color wheel problem.The color wheel is a rotating disc that has a gamma of colors it spins at high rpms.The light of the lamp goes through it to create the colors on your tv.When it starts to go bad you will get color distortion ,black and white picture and sometimes you will hear humming noises.I found it with complete light engine assembly here: http://www.discount-merchant.com/TOSHIBA-2973026206-p/1160068.htm?Click=48173

Toshiba model #46HM95 picture dims and brightens occasionally and just started to turn off by itself.


Replace the lamp first. If that does not fix it then you will have to send the light engine to Toshiba to be rebuilt. The ballast is bad but is not available any more.

Toshiba 44NHM84 won't turn on


Usualy these problems are due to solder evaporating under the heat of the component.If you are a competent technician,by opening the tv set and by looking closely on the solder part of the board,
you should see a few that are not as shiny as the other, or look like a donut around the pin.these should be redone.those failiure are around the components that heat up:voltage reg,h-v reg and the
resistor around them.
good luck

Humming/buzzing sound


That could be either the ballast, or colorwheel. Does the sound get louder at the rear of the tv or louder in front. let me know I may be able to help you.
