Testimonial: "This is what i am referring to, it is a warning on the ShopJimmy site when I lookup the LED Driver I need. My question is this, if I can see the menu on the screen when using a flashlight, is it possible it is no the LED driver but the LEDs? PLEASE NOTE: Models that use this power supply are also HIGHLY susceptible to LED failure. What may seem like a power supply failure may be caused by the failure of one or more LEDs inside the panel (screen). We stock most LED strips for the models in question. Please search your model number to view the available LED strips."
