Sorry, was looking for a critique of the overall design..Thing smoked pretty bad and the diode rectifier had de-soldered itself..I don’t repair these anymore. Shop around and you can probably get one with higher capacity for under $10.
OK, a critique of the device is that it does have an input filter but not an adequate one, and it looks like it may have a MOV to protect from line spikes, but if that small tan block next to the yellow block capacitor is not a fuse then it is not protected. Most of the control circuitry is surface mount on the underside of the board and so it can't be seen. If you have the specifications you can get another supply and be back lighting the LEDs.
