Hello everyone, I tried to find out some threads regarding the same issue I am having, but the forum 2007-2012 does not work. My problem BS5/BM5  is that until it's working, is working fine, but if I have a power outage at home, or I give the command "restart" from "service menu", the BS5 can't get to boot, and I have to try more and more times (even 30x), switching it on and off, to get to boot it. When I am lucky, with 2 or 3 attempts I get it, but it doesn't happen so often. When the device can not boot, it appears the message in the attached file "BS5 Screen error" Does someone have the circuit board diagram of the 2 boards inside Beomaster 5 (a pic of the main board is attached as "BS5 Main board") With them my repair boy certainly would fix the issue. Keep waiting, thank you in advance
