Question about Polaroid Televison & Video
TV Part #DE550M3N4AU-YA4 Power supply Part # MIP550D-TF1
It is dependant on how many LED's are present in the back light LED array. IT can be 35 to 60 volts. In most cases the power unit does not fail, the LED's do because they are pushed to their maximum output for the illumination of the screen. All it takes is one LED to go bad and the rest wont come on. The diagrams for the unit are not posted

If the desktop charger is the version that can accommodate two radios simultaneously similar to the T5000, then the AC wall adapter or the power supply is 9 volts AC.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.

On the power supply board I replaced CAP C226 as per another poster and the problem is solved. It is a 470 uF, 35 VDC capacitor. Bought one at Radio Shack for <$1.50 USD. Radio Shack part number is: 272.1030.
