Pretty sure it is the mainboard I tried testing the very thin wires and connectors from the mainboard to t-con and got nothing so the mainboard is not sending anything to the t-con which is probably on the same circuit as the bl on volts.

Re: Insignia NS-LCD47HD-09
Ok tried to jump bl on with 3v did nothing. I also see no picture/menu on the screen with flashlight. Just strange to have all the correct voltages besides the bl on. I did notice I have a ribbon cable from the t-con board to the master inverter would that be something to do with the bl on feed thru the t-con? I tried removing the ribbon from inverter then jumping with 3v but still nothing.Leave a comment:

Insignia NS-LCD47HD-09
Hello all, first post. Got this older TV for free has power but no backlights or picture. Tested voltages and it seems everything is there but the 3v BL ON. I know the inverters are a common failure with the fuses but they checked good on this one. So my guess would be the main board having a faulty component? Or does the BL ON come directly from the power board with the 24v to inverters? -
