Shuts off after 5-10 minutes - power supply or main control board?

I've spent hours reading through this thread but cannot clearly discern whether I need a power supply or a main control board for my PN60E8000.

Upon good power on, unit will shut off anywhere from 5 minutes to hours later. Front lower left red led flashes in the following cycle:

short (a quick flash), medium (maybe 1 second), short, medium, short, medium, short, medium, short, long (4 seconds)
... repeat ...

I then unplug it, wait, replug and turn it back on. Works fine for 5 minutes to hours and then shuts down again.

I don't know how many are still following this thread but can anyone tell me whether I need a new power supply or main board (which is much more expensive)? I'd like to believe the LED cycle above would tell us something but I couldn't find anyone referencing the flash code it is giving.
