Hello,
I have the HITACHI 42PD3000E Plasma TV that comes with the external "media box" called AV3000.

The behaviour is that when I power the TV set from the remote, sometimes it turns on and operates normally and other times it makes a "clicking" sound, like relays going on and off, and either turns on after some few clicks or repeats this loop. In most cases, it eventually turns on.

I did some research and someone suggested that the switching regulator MOSFET I901 and D911 Zener diode need replacing. I unsoldered the diode and tested it...
