Power Supply 17IPS16-3

[steffen55]

Hi all,

please could you help me with some basic troubleshooting hints for a Vestel 17IPS16-3 power supply from an LCD TV.

The power supply seems to have no output at all. I can measure a voltage of ~325V at the primary side of TR800 but no voltage at all at the secondary side. Looks like it's shorted.

Are there any inputs to locate or at least to isolate the fault?
