Hi there, new member today and still learning about B&O. I have just got a AV9000. The monitor originally worked fine, firing up, screens opening etc but today I just have the red standby light, it briefly goes to green when selecting tv but immediately goes back to red - what am I doing wrong?
Also the video / control centre displays Error SW.1.10 and Error 0. I have checked all the connections and the masterlink is in the bottom slot of the monitor but the message is still displayed. all I can do is eject the tape at the moment! Any guidance hints etc gratefully received! cheers
Hi,
Welcome to Beoworld. One of my AV9000s had the same fault when I bought it about 4 years ago. Replacing C101 fixed the problem in my case. It's a blue capacitor found on PCB4 (Power Supply & Deflection). It's rated at 2,2nF 1500V according to the service manual, but changes can have been made through production, so it's sometimes best to look at the original component - the one I took out seems to be 1600V.
It's a pretty common fault if I remember correctly and it's a fairly easy fault to fix - if you know what to do do and what not to do inside high voltage equipment that is!
The replacement capacitor I bought was 1,5 times the physical size of the original as it was 2000V instead of 1600V, so make sure to look at the physical size as well. I can't remember if I made it work back then by bending the legs or if I took one from a donor chassis, but it's definitely easier and better to get the correct size.
I added some pictures to show the size - the small cap is the old and the big is one of the new ones I bought (Yes, apparently I still have the old, faulty capacitor 4 years later for some strange reason...):
Old:
New:
But if you aren't familiar with repairing high voltage equipment, then I would strongly advise you not to attempt to repair your television yourself, as you could get seriously injured and/or damage your television even more. There is no guarantee btw. that changing C101 will fix the problem in your AV9000, so some know-how could come in handy. I have found a Danish website with other suggestions on what could be wrong though, so if it turns out that C101 isn't the problem, I would be happy to translate them. Just wanted to start with my own experiences.

Hi Dennis many thanks for your reply. Sadly I have no great knowledge of TV's so thinks its best I don't jam a screwdriver in there! I think I need to find someone capable local to me in Surrey / Sussex. If you know of anyone that would be great, if not do I need to re-post this as a new thread request? Thanks for your help Regards
