Panasonic Viera TC-P50U2 lost picture after a ‘pop’ sound

Panasonic Viera TC-P50U2 lost picture after a ‘pop’ sound the pop sound is similar to the sound made when it initially powers on. I’m getting the 10 flashes, but I know the error codes can vary model to model. My television doesn’t have any cooling fans that I can see. ANSWERS:
