How To Test LCD/LED TV Power Supply Boards(No Power)

Learn how to test LCD/LED TV power supply boards before buying a replacement. The TV power supply board under test in this video is from a Coby 32" LCD TV. Testing boards from other manufacturers or LED TV's should be very similar. Once the power supply board has been removed from the TV with the power cord still attached, the next step is to turn on the power supply by shorting 2 pins together(Power On) on the power supply board. Coby models use the designation, "PSON/5vSB". Other brands may differ(such as STB5V). Refer to the video for more details, and make sure none of the Electrolytic Capacitors are LEAKING or BULGING. If they are, replace them.
