Lamp needed replacement. Changed lamp and TV still does not work. No picture or sound, just a buzzing noise. When on button is pushed the TV acts as if it is going to start up but only buzzes and makes a squealing noise. After it tries to start up and doesn't happen, then it sounds like it tries to shut itself off and then tries starting back up again. This continues for a minute or so and then finally does shut itself off showing all three lights again (timer, power, standby/high temp).

Yes, loud pop sound was broken lamp in tv, replacement of lamp will fix tv problem. Lamp replacement procedure is easy and would be written in user manual. Please buy Sony original lamp for good picture in tv. Thanks.
First. The whirring or buzzing sound you hear is the Color Wheel and it needs to be replaced. Second, since I do not know when and if the original lamp has been replaced it is a good idea to replaced the lamp. The bad Color Wheel is the one causing the set to shut down.
What it sound's like is that the lamp ballast is the problem. Buzzing sounds like when the power is first brought to the ballast it has to ramp up the voltage to get the lamp to light, then the voltage drops back down when the lamp is lit. Sounds like the lamp ballast isn't ramping up the voltage the way it should. May have to replace it. A good service shop would be able to do this for you. Blessings, A/V Media Guy
