Hello. I am repairing a Vizio sv471xvt and it had no standby led and wouldn't power on, so I ordered a used power supply and now the tv has standby and powers on but the screen is dark. I have to get a flashlight to see the menu on the screen, etc. Does anyone have any experience with this tv, to tell me what components need to be replaced to get the backlight working, because I'd hate to wait another two weeks returning this board and getting another one. I hate the backlight inverter is on the power supply with this model. Also, if anyone knows what components to replace on the original board...
