Check the +170 volt  test point on the power board (not the power filter board, the one that the plug comes into) but the one to the right of that board. It has a 5v test point (TP +5v) , a +170 and a +70. I've found that the +170 transformer goes bad, and won't allow you to adjust the voltage using the pot screw.

I have a 2006 Hitachi Ultravision 42 inch plasma

plasma tv units use a lot of power ,well into the hundreds of watts 9 some big screens use up to 800 watts to work)
I suggest that you consider a new led unit which uses barely any power and you will get a remote with it

I have nec plasma sync 42mp2 but no remote

Usually many plasma's have their controls on the side of the screen including power, so I would check their 1st.

As for getting a remote, harmony (now owned by logitech) makes some great remotes. One of the advantage of their remotes is that they are programmed from the computer by entering the model # of the items you wish to control. So you would just enter the NEC model to program the tv.
