    I've tried playing around with the settings in an attempt to rid myself of the noise but to no avail. The only thing that seemed to affect it seemed to be the backlight. Should I look into purchasing a new tv or is there a solution?

Hi there, (as far as I know :P) all these tv/monitor cords are the can even use the one from your home computer. If you have a homecomputer try that powercord, if that works. then thrifstores are full of these for around a dollar. Radioshack and the like will have them too, but it could run upto $20....You can also try computerparts stores...These cords are all over. I have an old crt monitor of wich the power cord fits into my 2008 32" lcd tv....

Good luck and if this has (or not) helped you, then please rate, thank you!

There are two possibilities here.

The first is that you've had bad power board.
NS-L42Q-10A is known to have issues with the power board.
You can read more here:

The second option is that you have a bad main board. This also not unheard of and since you were able to get it to work with another power board it is actually the more likely case.

What I'd do if I were you is try to heat the main board a bit with a dryer to see if it will start up more easily in that case.

Do not overheat it though.

Sometimes it's just bad capacitor that needs time/temperature to work good.

Other times it's bad solder, usually on the main microcontroller, which needs higher temperature which expands the metal until it makes good contact.

Other times it is something else.
