Zenith SF3537H

[Giambrone]

Can some please help me. I am having a problem with my Zenith System 3 Digital TV not turing on. One day it was working the next day it would not turn on. I had a tv repair person say he thought it might be the power supply module so I found a rebuilt one from a Zenith Dealer in NY but it made a spark when we plugged it in but still will not turn on. Any help would be appreciated.
