Re: No power to my Hitachi 42hdm12
If even trying the TV in another known good outlet, it still doesn't work, do a hard/full reset - turned off via master power or unplug for a couple of hours.
If all else fails, maybe you should seek the services of a qualified professional since this involves opening the unit, circuitry diagnosing and board/component repair/replacement.
Hope this be of some help/idea.Post back how things are or should you need further information.
Good luck and kind regards.

Convergence problems are usually caused by a diode on the convergence board. These little critters have a tendency to short out and cause the convergence to do strange things.
Obviously, this is not a job for the home owner because few of you know electronics. So, call in the technician to make the troubleshooting of the circuit. The diode costs $.98. The technician will cost you about $250. Don't ask me to explain it.
That's the way it is today.
The Zsus and or the Ysus boards are common failures. You can unplug the Zsus board from the power supply and if the power stays on, I would replace both the Zsus and Ysus boards.
I hope this helps,
