How to identify which connector is positive and which is negative
I’m having an issue with D55un-e1 LED tv. LED driver/power supply is not working after using a multimeter. I wanted to check if it’s the backlights so I got an LED tester. However, the connector points do NOT indicate which connectors are positive and which are negative. (Power supply board : PLTVHU401XABV).
Here is the picture of the connectors
Could anyone please help me with where to stick my negative and the positive in this situation?
Thank you so much!
