Describe the past - How did it fail? One day or acting up for a while? Could be a weak power supply - a bad capacitor on a power supply too. Look for popped up capacitor top inside.

Plasma tvs do not have "back lights" LCDs do. you probably have a bad driver board along with the upper or lower buffer board or maybe both, best to have a tv shop look at it.

Replacement power supply is used?
You need to verify the DC output voltages of the power supply first and make sure this power supply has no bad caps with leaking/bulging tops. It goes into standby can also be that it detects fault some where in the set.
Please see my basic troubleshooting guide here:

Learn about bad caps: http://en.wikipedia.org/wiki/Capacitor_plague
Capacitors kit: http://lcdalternatives.auctivacommerce.com/Default.aspx he can make you a set of caps.
Or www.digikey.com, just make sure to use caps with low ESR, 105c, high ripple current and long life rating such as PANASONIC FM or FC series.
Please post back what you find.
