Toshiba 46HM95 Buzzing

I have a 2 year old Toshiba 46HM95. There is a loud humming/buzzin noise, but the picture and program sound have not been affected. It seems to be coming from the vent area in the back. After the t.v. is turned off and cools down, the noise stops. Suggestions?

    I have the same television, mine is apx 4 years old. I had the same issue, I had to replase the unit that the lamp plugs into. Mine was under warranty so I couldn't tell you how much it was, but the toshiba customer service line is very helpful.

    Had this problem in January on my 2 y/o set. As time went on, the buzzing would start sooner and sooner after the set was turned on. Turned out to be the optical engine, which had to be replaced. There was an issue getting the replacement part from Toshiba and it took about 7 weeks, but once the part came in, it was only a couple of days. Fortunately, I'd purchased the extended warranty, because the service guy said the charge was $800. Good luck.

    I have a two year old 46HM95 the cooling fan has become loud and it kind of hums or buzzes.There are no other noticeable effects on the performance of the TV.

    I have tried cleaning any dust that has accumulated around the fan or any areas where the fan may be drawing air from.The noise remains the same.

    Buzzing sound just started today. The sound stops immediately after turning off the TV. Still trying to figure out exactly what the problem is.

We are experiencing the same problem. we just put a new lamp in and right after we turn the tv on it hummmmmms then we cut it off and it hmmmmms for about 5 mins then just stops any suggestions

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.

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:
