      Hi, I have been told by B&O that my 2002 Avant TV cannot be fixed. It has green and purple haze down the side of the picture. Does anyone know if this can in fact be fixed? B&O also told me that if I wanted to continue using my 8000 and 6000 speakers I would need to spend £5k for a connection box!!! I now know that Steve at Heavenly Sounds can provide me a connection solution for a lot less! So it make me doubt their assertion that the tv cannot be repaired. Anyone have thoughts?

        Hey,

        I myself have 2 Avant 32″ (the DVD RF) and they are lovely TVs, as you’ve found out B&O do not want to help CRT owners in anyway and it is soul destroying if you really enjoy the device.

        Depending on what you want to do do with the speakers you’d either have something like a beosystem 3 or 4 or an almando Multiplay Surround Switch – something like that – or perhaps a 3rd party AV receiver.

        The staple answer with older electronics is replace capacitors, and my friend actually has 2 broken Avants on my list to look at, do the caps and see if they come back to life. The key worry would be if the tube has failed in some way or a chip that is essential to operation has or is failing.

        I guess I would say – where are you based, how precious are you about the Avant, could you find a replacement Avant local to you? although bare in mind they are all getting older and going to eventually face various different failures. Can you perhaps post a picture of the fault?

          Hi David. This TV image in attachment should be a white background. You can clearly see the colours bleeding in from each side. Any thoughts on a fix?

            The problem you have is the classic degaussing issue. The problem is caused by magnetic interference which normally gets cleared when you switch the TV on. There is a degaussing coil which is around the tube which is energised for a few seconds when you switch the TV on. When you switch the TV on you can hear a short hiss when the degaussing energised.

            However, if the TV has been in store for a period particularly near other electro magnetic equipments it can get very magnetised and the built in degaussing may not remove it. Also of course it may be that the internal degaussing circuit is not working.

            To check if the internal degaussing is working switch the TV on after its been off for say 30 minutes and for the first couple seconds you should hear a rushing sound. If you don’t hear it, then that may be the fault.

            I inserted your image into the post to make it easier to see rather than have it as an attachment.

              OK that isn’t the issue I was expecting! Have you moved the TV or put a MASSIVE magnet near it? because that is a magnetic issue that the tube usually has a degaussing wire to compensate and correct at power up.

              when you turn it on do you hear like a ‘dongggg’ noise? have you tried unplugging it for a while and plugging back in (it might trigger the degauss, or set your stand to go from different on off positions as there is a degauss correction angle in the service menu of these TVs which I’m not 100% how it functions. either way it seems the degauss hasn’t worked. you can get external coils for professional use but that isn’t necessarily the answer – I wonder if a cap has blown in the degauss circuit and its now not working.
