Hey everybody I have a generic chinese-made COB X5 1500W light. When I turn it on, at first all of the 5 cells light up but after about 2 seconds one of them goes out and doesn't come on again (always the same cell). I tried searching online and in the forum here but wasn't having much luck finding anything. Does anyone know how to troubleshoot these or is it just dead and not fixable? Thanks guys
