<h3>Hi B&O fanatics,</h3> i love the beovision 10 series. I sold mine in working condition ;-( Now i got another one with a problem, which i couldn´t solve so far. It´s a 9553. picture is there, fire tv stick is working. Excellent picture. But no sound at all. a connected Beolab 4000 will be powered on (5V signal) but also no tone. Even the test noise in the sound option menue is not working. As far as i know, the power pcb has been exchanged (old one died) - i don´t know if there are different types for the different mk versions and now the wrong one is in. Would be glad, if someone could give me a hint, how to fix that stuff. I would like to reuse it (has the nice black frame) Best regards 69er
