Hi all.
I am trying to diagnose my visio vw37l
I have only orange light
5vdc standby voltage present on output of power supply but no "ps on" signal present at power supply when power button pushed.
I was reading another thread and they suggested unplugging the inverters (the other two output plugs of power supply i'm assuming) with no change.
anyone have any ideas on what to test to isolate (seems like main pcb maybe?)
Two fuses i could find on main pcb by the input cable test fine
I also have my 5vdc control voltage at switch/button board
thanks
scott
Update--- I unhooked all connectors on power supply and hooked 3vdcto "ps on" input pin, the power supply voltages 12vdc and 24vdc are present on output pins of the 3 p/s connectors. so p/s appears to work when it gets the "on" signal..
any ideas why the "p/s on" is not coming from main pcb?
Added pics--- Thanks for the reply
