Will the power board from a 15" LCD HD/VGA TV power a-like 19"?

This TV has a PC interface VGA (HD-15) , so all you need is get a VGA to VGA cable to plug between the VGA output on the PC and TV.
On the PC select the display as external monitor.
On the TV pick the PC input as required input, not the TV tuner.
Here is the manual.

LCD TV 47HL167 Support Toshiba

Looking at the specs for your TV, it does not appear to have the jack for earphones.

You will have to connect an audio receiver to your TV and use the reciever's jack.

What gaming console are you using?

Do you mean the power switch does not shut it off, or do you mean it does not show the signal you want it to show?

I can't help you over it not turning off, but if you are not seeing the signal, it may be because the TV has various alternate inputs, and has to be switched between which one you want to show, such as:

2 x HDMI input ( 19 pin HDMI Type A ) - rear
1 x VGA input ( 15 pin HD D-Sub (HD-15) ) - rear
2 x S-Video input ( 4 pin mini-DIN ) - rear
1 x audio line-in ( mini-phone stereo 3.5 mm ) - rear
5 x audio line-in ( RCA phono x 2 ) - rear
2 x component video input ( RCA phono x 3 ) - rear
2 x composite video input ( RCA phono ) - rear

Try using the on screen menu to bring up a choice over which input to show.
Switch it to the one you have connected to it.

You need to read your HD digital tuner and see if you can lower the video resolution to the maximum the monitor can handle, right now it is too high for the monitor to display. If the resolution is OK then the problem is in the monitor logic board.
