Backlights turned up to high and they are pieces of crap, cheaply made, disposable by design.

32" TV with blown LEDs may not be worth fixing?



I found in my salvage pile of LED Strips some with the same amount of LEDs.

That's the most damage I have seen from led burning out. Was it hit by lightning?
