Why will my Sanyo LCD led tv not light up?

I have a sanyo 32" LCD LED TV model #dp32d53. The other day I turned it on and it turned on fine showing a gray screen with the channel number but then all of a sudden the screen went black. It still has sound and the screen still works I did the flash light test. The TV has the main board/ power supply/ backlight inverter all on one board. From what I found out online if the screen still works but its not lighting up its probably the led driver/backlight inverter so I ordered a used board from a web site that said it came out of the same model TV with a broken screen. I just got the part in the mail today and changed the boards out but it is still not lighting up. If anyone could please help me I would be very greatful. Could it be the actual LEDs? If so is it a costly fix?

@mjkbuddha87 unlikely that all the LED's would have failed. Post some images of your boards and wires with your question. For that use this guide Adding images to an existing question

It sounds like you are still having an issue with the backlighting. If the LEDs were bad, you would have no picture (fail flashlight test), I would think. Could be a fuse or connection issue in the backlight cicuit. Try searching for a schematic and test the circuit.
