Hi Chipped Rice
The loud buzzing noise you heard was the colourwheel that gave in.
Now what happens is , the machine will turn on and go through the whole cycle and as soon as the colourwheel is supposed to start doing it's stuff the Projector will switch off because there is no response from the coulourwheel itself.
You will have to replace the colourwheel unfortunately as it cannot be fixed.
Thanks for using Fixya !

Possible cause is overheating.
Do you hear the fan working?
What happens when you use the lowest level light output?
Does it run longer?
Also possible cause is a faulty temp sensor.
AC wire connection may not be firmly pressed in socket.

If the word "OVERLOAD" is in your display, we have a bad channel.
But if only turn off, and the standby led is on all the time, you need change a couple of resistor of 10 Ohms at 2 Watts in main board. But you need disassamble a must all the amplifier. A lot of work, but cheap part.
