Schematics & Help Needed. No Backlight Voltage

[claudyu07]

hi Guys. i have this tv here with power board LEKE LKP-SP017 REV:0.5 and i can't find schematics at all.

Tv switch on and working fine but no backlight.
No +24V on power board for inverter.

I have switched on TV, disconnected +24v cables from power board and used external power supply with 24V for inverter and all working fine.

Thanks very much.

Re: Schematics & Help Needed. No Backlight Voltage

Make and model of the TV?
What control signals (PS-ON, BL-ON, etc.) do you have feeding the power supply board?
We also need to see the whole back side of the TV to see how all the boards are connected together.
