Over years of exposure to seasonal weather variations, the internal capacitors within the driver degrade due to trapped heat.
The root cause is almost always a failing constant-current LED driver (specifically the original shipped with many fixtures). This driver converts 120V AC household current down to the low-voltage DC required by the TVZT chips. Over time, exposure to fluctuating outdoor temperatures degrades the internal capacitors inside the driver. The driver struggles to maintain its 700mA output, entering a continuous cycle of shutting down and restarting, which creates a noticeable blinking or strobing effect. 2.

The TV produces sound, but the screen is completely black. You can verify this by shining a flashlight onto the screen while the TV is on—if you can see the image, the backlight is dead.
If you choose to complete a repair using a retrofit kit or an alternative driver, follow this layout to work safely: Failed MD:LED-D35-2 LED Driver in Outdoor Fixtures Over years of exposure to seasonal weather variations,
When used with aluminum PCBs, the 3030 package allows for superior heat dissipation, increasing the lifespan of the backlight.
