Opuradio RNS 510 bad mainboard
They are not able recognise and discard BAD mainboards RNS510 after reflow or they not tested it at end of repair line at all, who know. They sell this mixture, but not accept complaint of functionality! Ali will not support You, it is shame. Opuradio store on Ali have "no feedback" -why and how it is possible? Ali is accomplice? Dont know, but know that they arent good boys and it was wery bad idea buy mainboard there. Lost 140usd. Peter
