My phillips is making a loud buzzing noise, no picture, then it shuts off

See attached photo: you have a bad color wheel----it turns at about 12,000 rpm and bearings in the tiny motor go bad.

High pitched or fan like sound is classic symptom.

The wheel is available on the internet and You Tube has video instructions by model number for replacing it---Google the model number for the part number for your set to locate the part and instructions.

This for most people is a do it yourself job---takes like 45 minutes start to finish.

If color wheel slows too much set will shut down as its speed is monitored and the wheel can even shatter causing shutdown of the set.

have someone check speaker ground to the TV chassis. Your speakers are picking up reverb from the Video Signal.

buzzing noise is cause by small electrical arc inside the unit or a problem in your audio circuit.if you can open the unit up and check if its an electrical arc.

Your color wheel needs to be changed. Mine just did the same thing. I changed mine, and the buzzing sound went away, however now my picture washes out with light or yellow colors. The darks look green and purple also.

Does the DVD player still work, even though it's making the humming noise?
The humming noise may just be normal for that machine. Turn your TV up louder .
If the player doesn't work, the drive is broken, and you would have to send it to Phillips if your warranty is still working. If the Player still works, check to see if the disc is warped or cracked, this'll make the drive unstable, and make the noise.

Hope my answer helped :)

this can happen with the flyback transformer's brightness which can be adjusted , also the power transformer can make humming or buzzing sounds which can't be adjusted , also this can happen with the picture tube or the CRT board failing , and sometimes chips with heat sinks or the IC's themselfs

Mine does this too, just bought it yesterday and noticed the sound this morning, I guess because the house was quiet, now it's the most annoying noise ever. I have been searching for solutions all day, one forum said to go to the picture settings and turn the light sensor to "OFF"...Haven't gotten home to try it yet, but I hope this helps BOTH of us!

I purchased a poloroid tv 3732 in may of 2005 from circuit city, after about 14 months the set began making a clacking sound and humming sound that gets so loud it is unbareable. I have to turn the set off. I have found out I am not the only one with this problem that has a poloroid tv. I had a technician at my home that told me there is a service warranty on these sets because the wrong part was used and the part needs to be replaced.
