Bush BTVD91216 LCD TV power supply fault

[bearsdown1]

Hello everyone.  As an old CRT television repair man I have not really stepped up to the plate on LCD TVs yet.  However I promised an old customer I would look at her LCD TV for her.  It has power and a red LED lights but is not coming out of standby.  Monitoring the small power supply it is making 12vdc Ok but on main PCB some chips do not have a 5v supply.  Has anyone got a schematic for this model or even a make and model that uses a similar chassis or has anyone seen this fault before?  Any help will be appreciated and start me on the road to LCD repairs.   (I am now more into repairing stage equipment - better support from manufactuureres.)
