      Greetings from Hamburg/Germany!

      I was an avid user of the old forum for many years during the early and mid 2000s – unfortunately, the old user database seems to have not been migrated to the new forum, so here I am as a newbie. 😉

      Although I usually tend to stick to the old stuff from the 80s and 90s, I am using Beovision 7-40s throughout the house, most of them MK5. Not even the first MK1 versions that I gave away to family and friends have ever failed me – they seem to be just as sturdy as the good old Philips-tubed MX7000s.

      Not so the Beovision 10-46 I have recently acquired. After a few hours, it started to display only colorful lines. Maybe the panel has given up, maybe some capacitors have leaked – who knows.

      Before I detach the speaker cover and throw the rest of the heavy thing in the next recycling bin, I would love to have a look inside.

      I consider myself relatively handy, but so far I have failed to open the damn thing’s back cover.

      There must be a trick, right?

        Problem solved – an old man living in a cave full of ancient technology hidden away from the world occasionaly shares his wisdom in all things B&O with us mere mortals before he vanishes again for decades, and I was at the right place at the right time.

        So here we go: The internals are accessed via the front of the TV – at least in the case of a 10-46, in order to gain access, remove the screws at the bottom, then flip over and gently slide off aluminium frame and glass, and you’re in. Have fun.

          HI All

          has anyone had a problem  with the Beovision 10-32 it turns on but no picture, I think there is sound ? the screen shows a very dim blue.

          any help would be greatly appreciated

          Kind Regards

            Revisiting this – the power board on my Beovision 10-46 blew up and I’m trying to get access to the board (PBC04).

             

            I’ve undone the 6 screws at the back, but can’t see how the aluminium frame and glass ‘slides’ off. I can’t find a service manual that shows the removal of this – so I thought I’d ask if someone had done this – and how did they do it?

              Actually – never mind – it came off when I was lifting it off the stand. It seems like it pushes up about 5mm then just pops out.

              Before going to a B&O dealer or repairer – does anyone have a PCB04 Power supply for the Beovison 4-46 spare?

              The PSU blew up spectacularly with a lot of smoke – and quite a smell so I though it would be one of the power capacitors, but having taken the board out, I can’t see any blown capacitors.

                Found the busted capacitor – it’s a EMI suppression capacitor that failed with much smoke. Not sure that this is the only component that failed as the screen did go off when the capacitor blew up, but I’ll put a new one in and see.

                  Replaced the capacitor, re-installed – and all working again.

                    Great job 😀 And good to know that there is relativly simple fixes like replacement of single components that can be done on those newer ish TV’s where the service manusl only suggest to replace the whole PCB

                      I was hugely impressed with the build; I could open it while it was on the stand, and the modular approach of build was really impressive. The only weak point will be the panel itself and third-party electronics.
