    Testing Edge LEDs question?

    Hello, Professor budm, I need help!

    Both are Sharp Vizio Edge LED TV strips your can sub it with no problem.

    A tested 89.8v 34 LEDs 17 twinsLEDs reverse voltage is 13.89v it has 17 diodes.

    B tested 89.9v 34 LEDs 17 twinsLEDs reverse voltage is 330v? why it has no diode protection? Both are working OK in the same TV?

    PS: in the pic2, B looks like each led connected head to head (the last pic).

      Not all LED has protection diode. I believe there is lawsuit going on due to patent of the protection diode for LED.
