Hi all, I got this lepai lp-2020a+ from ebay, at first it worked ok but now no audio comes out from speakers, cant hear that click of the relay, no pop when powered, i opened the amp and tested with speakers bypassing the relay, capacitors, etc, but no nothing. Tested with various power suplies. also with one that i use with a lp-2020 model. The blue light is on. I waited with the amp powered on for more than 1 hour and nothing. Dont know what else to do.
