Hi Charles,

Sorry for the late reply, I'm offline upon purchasing my service.
You have said that you can hear a low buzzing sound before the unit gone to subsequent shutdown and the lamp blinks green(meaning that the unit try to turn on the lamp for consecutive attempts but not generally mean that the lamp itself is faulty.) and the temp led light come on.

As a matter of fact all the information you have mentioned linked to the symptoms you've encountered right now. A low buzzing sound might be caused by faulty FAN inside the unit that trigger the error code (blinking of the standby/temp led light) and turns off the unit automatically due to thermal protection circuit.
However, the technician might be true also that the buzzing sound came from the faulty color wheel. To confirm it, you have to verify where the buzzing sound came from. Color wheel is in front of the lamp assembly. Faulty color wheel can produce the same symptoms you've encountered right now but most of the time, it shows 3 blinking led light at the front panel (Timer, Lamp, standby/Temp).

I would advice you to open the back cover of your unit, fixed the lamp door safety switch with the tape to make it in closed position( if it is on open position the unit will not power up), and then turn on the unit and observe the fans if will spin or not, and check also where the buzzing sound came from before the unit gone to shutdown.
I've suspected that the fault came from the fan based on the led light flashes. Please let me know what you will discover after following the steps above to verify where the exact fault came from. Also, let me know the exact status of the led light at the front panel, (Timer, Lamp, standby/Temp ), which of them lit solid/blinking, it will help us to narrow the caused of the symptoms.

line o/p transformer &transistors are gone .. any service person can replace them

replace the lamp only takes few min make sure you get right one for model of tv the LAMP MODEL number will be on OLD LAMP the tv will work and sound will come back hope this helps

if the house lights flickered i would contact your insurance agent and tell him what happened it's possible they will cover the cost of repair, i would not ignore it it could lead to bigger problems .

If you have sound but no picture it means that your power supply and tuner are working correctly. The number of times the timer LED blinks is the code for the problem with the picture. The computer will stop the picture and blink the timer LED if the vertical circuit stops working, if the picture tube is too weak or if the horizontal sweep has stopped. The set should be serviced by a qualified tech familiar with Sony sets.
