Yeah Plasmas don't have bulbs....the entire display is one giant Flourescent display.....
So it needs a + 180 V, a - 180V a - 65V supply along with lower voltages to process the Video and sound...
Since you have SOUND, the low voltages are OK, but the MAIN POWER voltages are seeing too much current flowing and it's shutting down the display to protect it.....
I suspect an IMBALANCE in your Xsus, Ysus (or Zsus) board and it's tripping the shutdown circuit after 20 minutes of warmup time.....
Now all you have to do is determine which board is at fault...

Maybe you need a new bulb.
