I have the same problem. I have been fighting with Toshiba Canada since March to repair it, replace it or refund my money. In June, they acknowledged that is an issue but will not do anything about it.
Here is the post
I am sending them a letter asking for something to be done and failing that I will be taking legal action against them.

It sounds like you have a quiet cooling fan problem. Those particular types of tvs are notorious for that kind of a problem after a couple of years. You can take the back cover off and remove the fan. Pretty straightforward and go to an electronics supply house and ge a matching one. That is your best bet of fixing the problem for yourself. God bless you.

My Toshiba 37av502u loses it's settings

As goofy as this might seem, a large accumulation of dust inside the TV chassis could be the culprit. The dust becomes conductive and drains the charge from the capacitor that keeps the memory "alive" while the set is powered off. I'm a 40+ year veteran TV technician, but I've specialized almost exclusively in antique (1940's to 1970's) all vacuum tube sets for the past 15 years. I can get a dead 1946 RCA 630TS 10" B/W TV (worth about $2,500 as an antique) working again with about 10 hours of bench time. My new roommate, a lady I've known since we were kids, brought a Toshiba 37AV502U with the same "loses its memory" symptom when she started renting my spare bedroom recently. I opened it up looking for a bulging electrolytic capacitor or a dead RTC battery like some computer motherboards. I didn't find any suspicious capacitors and the only batteries this set uses are the AAA cells in the remote. What I did find was A LOT of dust inside the set. Cleaned the dust out, put it back together, and the set is holding its memory now when powered off. Obviously, the dust was creating a shunt path that was bleeding the charge away from the capacitor that stores charge for the memory.

Our TV is making a loud humming noise. We think

It's likely your color wheel rather then your fan. I've replaced quite a few of these and the fans are usually good. Get and estimate - I generally charge $250-350 Total
also google your model # and color wheel to investigate further.

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 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!!

I have a 44 inch 44nhm84 DLP. When the TV is turned on, it makes a loud humming noise that goes down in intesity twice and then finally a lesser humming noise after the picture comes on. At first I thought...

This does sound like a color wheel. To my knowlege, Toshiba does not sell the Color Wheel seporately. In short, you have to replace the Opical Block. The cost of this is very exspensive and Toshiba may not sell it to you. You may have to go through a Toshiba Service facility to obtain it. Check prices of new LCD sets before investing the money.
Hope this helps,

Humming sound from new TV

Thank you for the info. I would suggest to take it back from where you bought it from if the store will allow a 90 days return and replace it for a new one, or you can contact Toshiba to get it fixed under warranty. There should not be any humming noise on the speakers.
