Sony KDF-E60A20, buzzing sound, lamp light flashing red continous

Have a Sony KDF-E60A20, already replaced the thermal fuse last year, and a new lamp three months ago. But now there is a new problem, no picture/no sound.
The Power light blinks green when turned on and a intermittent buzzing sound comes from the rear of the set, like a beard trimmer almost, and finally the power light turns from green to constant red followed by the 'Lamp' light blinking red continously non stop every second.
Any suggestions on how to fix it?
