The BDM9 would appear to solve the flashing mild problem. I see it's got a Stereo/Mono line output for just a separate amp/subwoofer. I'll seem a lot more closely at it and will probably place 1 on buy. I have by now constructed a TPS3255 using the 3E board/electrical power https://pingdirapp56.directoryup.com/servicios/displays-holders
