Any way to bench test an LCD TCON board?

[tucocaps]

I've got a small Samsung LCD. History unknown. The mainboard appears to work (system powers on, and has sound), but the screen is dark. I'm assuming the inverter is shot, and I think the panel is damaged. Would like to salvage the TCON, but is there any way to know if it's good? Thanks.

OK so I guess you assumed the Inverter is bad because you have BL-ON signal and 24V to the Inverter? You could probably have a good idea of the T-CON's condition by measuring certain voltages on the T-CON board. eg: Vin, Vdd, Vda, Vgh and Vgl. Also, the Gamma 1 to 14 voltages along with some others.
