Anybody have their set stay on for 15 minutes, then make a pop sound and go black? The blue light then flashes over and over till I unplug and replug it in 5 times or so.

I had the same problem. It turned out that one of the cooling fans get dusty and does not work. I opened the back of the Toshiba plasma TV and cleaned the failed fan, and it worked like a champ.

I don't know if you guys are still looking for an answer but turn the TV on where you can here that something is actually playing on the TV then grab a flashlight and turn all the lights off. Get real close to the screen and shine the flashlight on the screen. Can you see something on the screen? If you can then there is a very good chance that one of the inverter boards are out. This could be the slave or the master. For the 47" I actually have the same issue and have ordered the master inverter board. For the 42" I have both the master and the slave board and they are both working. So for the person that has that issue on the 42" TV if you want a board for your TV email me at [email protected]. For the one with the 47" flip a coin and order an inverter board for it either master or slave and try it. To determine which inverter board it is you would have to take the DC voltage across the start and then the end to see if you are getting any power. I hope this helps. By the way inverter boards usually run between 60-120 dollars each and the slave board on both these TV's are easy to install. The master is a little harder due to the power button board is in front of it and has to be removed first. Let me know if this helped.
