no display with bios from all theme. With old one have display but after shut down dead. Need to disconnect baterry and rtc and start again until next shut down.
I also solved this problem. This is a problem with the EC Bios program. In my case, NM-B452, the problem was solved by programming the IO chip
 
hello, which software do I use to open the boardview, since it has * .tvw extension
