My Predicta died today

[Captain Video]

This Predicta is not letting me have peace: today it malfunctioned again. I turned it on and immediately heard a small "pop" sound coming from the inside of the set. Them I waited, and waited, and waited... and no sign of life came from the TV, no sound, no light on the screen, nothing. The tubes inside the TV are lighting up, but there's no other signal of life coming from the set. What can be wrong now? The tech that repaired it will only be able to take a look on Sunday.
