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.
sounds like picture bulbs maby %30 i think it may need to go in for a check up they can pin point the problem hope ive been somewhat helpful thanks viper
looks like the color wheel its bad in the set,color wheel its not spining at its proper speed( one of the segments may be broken)
thats the vibration you are hearing.. and the set its trying to turn on..until you replace the wheel you will be able to watch tv again.
