If is is the fan it is because there is another part they needed to put in to keep the noise from the wheel barings coming through...there is some kind of kit ...i know cause i needed a new light engine and notice no noise from the fan... repairman said they now come with a kit that surpresses the fan noise.

The buzzing noise would normally be either a fan or color wheel that is failing.

Buzzing noise

It could be feedback from your speakers... Make sure your power cord is grounded and if you have a sub or surround sound don't set the ac power adapter near them.

What is with the constant buzzing noise?!

That buzzing noise is the power supply. You probably have a bad capacitor somewhere on the power supply. You can find and replace the cap or change out the power supply. Herre is a link to one at

MY HITICHI 50V500 HAS TAKEN LONGER to come back on after turning

The high-voltage transformer (same as power supply) is faulty. It is very common in todays electronics. The old one will have to be difused of all power with difuser. Then it will need to be soldered off and new one soldered on. You can get them at,, or and others.

Loud buzzing noise on vizio tv

It sound like you may have sound processor problem which is part of the main board, I would also look at the 12vdc from power supply to make sure it is clean DC.

If it is a buzzing noise, it is the Ballast for the lamp.
If it is more of a grinding sound, it is the Color Wheel motor.
Does it go away when you turn off the tv? If so, does it stop abruptly or does the sound tend to get softer (winding down noise)
If the noise stops abruptly it is probably the Ballast.
If the noise takes several seconds and seems to get softer until it stops about 30 sec later then it is the color wheel motor.

My Hitichi tv will not turn on. When the power button is pushed, the lights come on as if it was going to turn on. Then, the lights begin to flash as if the tv was turned off. After the lights stop...

This is known to happen. You could let it cool down for an hour. If it still persists, then it will need to be fixed.
You can also try unplugging the tv set for at least 4 hours to do a "hard reset"

The noise is caused by dust on one of the toroidal transformers(usually a round looking thing with wire wound around it). Go to the back of your television and try and pinpoint were the sound is coming from. Turn your television off and blow it out with compressed air if it is close to air vents in the television. If you cant see it you might have to open your television back panel.
