| Ok actually I think I express myself wrong.
I need the Inverter schematic ( the circuit which turn on the lamps ). Actually power supply and Inverter are located in the same board. Problem: When I turn on the monitor the Transistor on the Inverter board starts to warm and after a while is burned. The lamps turn on until the trasistor do not burn. Thanks for helping |

| Just perform generic checks.
First make sure it has no blown/bulged electrolytics. Are fuse(s) O.K.? Does main filter lytic have Raw B=Plus? Does Raw B=Plus make it to the regulator device? Does the regulator driver I.C. (and supply) have startup voltage and puts out drive signal to regulator? Do secondary supplies have correct voltage outputs (with or without loads connected)? |

| Very few service manuals contain schematics for power supplies.
