• Search the part number on the board, it may tell you other tv models / sizes and do an google search ...

• Not the exact PSU as the schematic given appears to be for up to 42" models:

  Possibly close enough to at least help understand.
  From personal experience with these psu's and from a first glance at the schematic beware of, (referring to schematic in link):
  
  (bulging secondary capacitors of course...)
  Bad solders on transformers
  IC901 (ICE3AS02 standby power PWM)
  C613,C625,C626 on main power
  C310,C311,C315 on backlight power

• thanks but this is not the right schematic.
  the broken circuit is a fairchild FSQ510, there is none in this manual.
  I replaced it (and a fried resistor)  but the power is still ticking (one relay is ticking in fact)

• the tick maybe a synonym of an short circuit still present, the supply tries to start and shutdown because of the short
