With all the listed sets,itis most likely the y-drive(sus) board.The only problem is that this board usually fails when the horz.buffer ic's fail,which is usually part of the plasma display.This was a semi-common problem with this set.The best bet is to find a new set,since the parts alone will exceed the cost of a new one.Pioneer or nec seem to be the most reliable that i have seen.

If the TV goes in standby, then it is in protection mode.
Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
Try first leaving the TV power cord unplugged for some times, let say one hour or so.
The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.
1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.
2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.
If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
If under warranty contact the manufacturer ringing the number on the user manual
If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

My 42 Inch Vizio experienced the pop of death out-of warranty. I bought mine at Sears and they sent a technician over within a day or so. It turned out to be in the power supply and they shipped a board right out. Total including parts and labor was $280. Although no expensive TV should die after less than 2-years, Sears seems to be able to deal with repair in the home without drama.
