Download the service manual.

At the risk of sounding sarcastic, I would have thought that someone who had been around long enough to make 66 posts would have already heard this. Attach pictures using 'Manage Attachments' (below the test entry area). Frankly, I suspect my 'Crystal Ball' line is getting stale.

Thanks Ronnie

If it is emitting a loud buzz then it is a broken panel. It is probably broken in the vacuum tube in the top corner above the buffers or along the edge of the panel near the buffers.
