Some component or soldering is degrading.
take out the circuit board and look for capacitors with shrinking plastic.then look for bad soldering.
if you do not know about electronics,do not mess with it there are 40000 parts in it.

Check your fans. You have a stuck fan. You may want to call a service center as it is a pain to get to one or two of the fans. Theres 3 or 4 of them.

hello .High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.

Sony Wega KF-42E200A Projection Bulb


New bulb is just fine.
3 blink shows that lamp cover after replacement of bulb in TV is not fixed properly or not seated well in its position.
Put new bulb and carefully place back lamp cover in its position because lamp cover will press tinny safety switch inside that will send signal to system control of TV that lamp is installed properly.
Turn On TV and get vivid picture of Sony.
Thanks.

Dead sony


The $1200 was for the lcd engine not the lamp. You should change the lamp. The buzz is the power supply trying to light the lamp.
