    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.

          Problem

          This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....
