I am trying to determine whether the power supply in a Polaroid UHD TV set is defective. All voltages are good except I don't know what the LED voltage is supposed to be. Can you tell me? Thank you.

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

SOURCE: lost power supply


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.

Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Se50fy10 backlight not working

This is an exact problem that I am facing with my Seiki 50" TV. From my research, here are the probable issues:
1. Main Board/T-Con Boards are fine
2. Power Board : MIP550D-5TB could be defective - most probably the culprit. There is a power test to try but w/o schematics, it is not possible to identify component
3. If Power Board replacement does not solve, it is the backlight LED strips that are defective - tought one to replace.
Will update this thread at a later date.
