Re: No power to my Hitachi 42hdm12

Hi, 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.

I was watching my Hitachi 42hdm12 and heard a pop and now the picture won't show up or sound or anything?

A pop is usually a power surge and you blew a board. If you take the tv apart, if this is it, it will be evident by the burn marks. You could have burned out the internal power supply as well.

We had a pretty bad storm now when I turn my Hitachi 42HDM12 on the screen is a redish pink color. How can this be repaired or corrected.

Hello, 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.

I turn it on and it turns itself right back off

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,
