Zenith SF3537H
 

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.

Did you see where the spark was ?
Also look at the fuse(s).
Was the new module still factory sealed ?
For now about all I can suggest is pulling the power
supply & HV board and check for bad connections, burned
spots.

Without the manuals this is one of the hardest TV's to fix
ESPECIALLY now that there is no parts made nor tech
help from the factory. Add to that there is practically no
tech that ever worked on more than a hand full. We
were a Zenith dealer & I think I did 5 or 6 out of the
maybe 40 we sold over the years.
Sorry but you gotta remember this set has lasted 2-3 times longer
than it was supposed to.

Anyone have the service manual for this tv (923-3334) or the schematic (923-3123).

It turned out the transformer on the power supply module was fried. I replaced it with a rebuilt power supply module and now it works. I would like to replace the transformer on the old board and use it as a spare. Can someone please tell me what the part number is for this transformer.
