When I turned my television off I heard a noise like a light bulb breaking. When we turned the television back on, there was sound but no picture

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

If your set all of a sudden won't come on, e.g., the screen is blank, but the LED on
the under the screen next to the on/off switch keeps flashing, then there may be an
internal fault on the set that needs to be reset.
To force the reset, try this:
Whenever the set senses an internal fault through its monitoring circuitry, it
essentially shuts down the set. The flashing LED provides the indication that a
fault has been detected. Removing power to the set resets the monitoring
circuitry. When plugged back in, the circuitry again does a check of the
system. If it finds that there truly is a problem, then the set is shut down and the
LED will again flash. In this case, you need to call a service tech. Most of
the time, however, the unplug/replug routine is enough to get the set up and running.

It's not a 1k Resistor but a 10k...it's the resistor R3 on the Circuit Board Part Number RPB-4434ZA (P/N: 23122468). If you don' replace the resistor you will keep burning your lamp. If you decide to replace the resistor by yourself...you should take the time to look at all the on the back of the board. This Board is made by the company Rubicon Corporation for Toshiba and it's a issue on the Toshiba DLP TV (62-52HMX84). If you don't wanna do the job yourself..bring your TV to a repair and give him the part number of the board and ask him to replace the board for you. If the price is higher than $350.00 go somewhere else...He try to fu....^&*%*%&%.

The internal fan kicks in when the set starts to get too hot.
Check the ambient room temperature to make sure it is not too hot in the room. Also note that some fans ALWAYS turn at some speed and if its making some sort of noise you dont like then it might just be dirty. try dusting it out.

my 46HM95 was humming also, I have the extended warranty and the company came out and diagnosed it as the light engine. the part was backordered and it was just fixed today, it was ordered back in February. Problem was solved.
