    What are you using for input cables?  HTMI Cable or red white yellow? or red white green blue red?  or are you using a coax cable input?

SOURCE: screen went black on my 42" sanyo model dp42647 lcd

Hi there! The panel may be in protection mode. The Inverter board is the most logical area to start after checking power supply Voltages.(5,6,24 and 13Volts). There may be coils on the Inverter Board which have bad soldering or faulty. Other than this it may be main board which controls switch on or off. If all else fails, refer to a repairer. Beware of High Current!!! Best Wishes and Good Luck, Jus004

You may have a defective inverter. The inverter provides the back lighting you need to see video. There is good chance the starting resistors have changed values. It would be best to replace the inverter in your case. I would have to have a schematic to find the bad resistors. Thanks for asking and show a few hands of support.
