Hello and sorry you're having problems. Offhand the 10 blink code on your set points to a hardware failure, which can be caused by multiple things from the power supply board to the Plasma display processing.

However it's worth it to try a hard reset, as sometimes the processor in the TV can simply have locked up.

The first thing you would try, is disconnect the set from power, then press and hold the power button on the TV itself (not the remote), for 10 seconds and release. Then plug the set back in, and also check that the power cord is connected tight at the TV as well. Press power once, and see if the set powers up normally. Try this procedure up to 2 times, and please let me know what happens.

Are you still having the same problem?

Expert:  Aric replied 19 days ago.

If you're still unable to get the set to power up with the 10 blink code, then this indicates a hardware fault in the set. This problem can happen due to several things. The power supply is a common cause of this problem. This typically will cost you $300-$350 to have repaired.
The other very common issues, are problems with the Sustain boards failing. They are responsible processing the Plasma display and are common failures for this type of TV. The average cost for this type of repair is around $400 parts and labor.
Given that a brand new 50" LED TV can be purchased for about the same cost as repairing this set, it may make more sense to put that same money towards replacement of the set- versus repairs.

Other than that, I'm sorry for the bad news and wish there were a quick fix.
