If the unit is not far out of warranty I advise contacting the manufacturer to obtain a possible parts or labour only warranty coverage, if not, your other option is removing the back of the unit and check for any faulty capacitors on the power supply printed circuit board. I hope this helps. Good luck.

2 year old Sanyo DP42848 Screen turns on for a couple of seconds then turns black... Audio works fine. Help!!


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.
