In this video, I'm looking at three failed Lambario 18W LED panels that all failed within a week. They are about 9 months old and they were not used a lot but since they all failed in a week, I decided to open them up and investigate the issue and the circuit.
The panels are driven by a driver marked as 1FYL9T2CC and I was unable to find any info on it. However, the circuit was similar to other LED drivers that I've found so I was able to figure out how it works.
The LED panels had blown LED and since their construction is done with a strip of LEDs in series, having a blown LED will cause a break in the continuity and will cause the panel to malfunction. An easy fix is to remove those LEDs and replace them with just a wire, so we can re-establish the current path and the driver will take care of the rest since it only regulates the current that goes through the circuit.
To make sure that they last longer now that I repaired them, I also did some experiments to try and reduce the current that goes through them by replacing the current sense resistor on the driver board. I tried several combinations and I finally settled at a variant that uses around 30% less power than originally and the light output is not visibly affected.
