Yes, I would check again in total darkness. If you see arcing at the HV capacitor solder joints, etc., you can try insulating them as Tom suggested. I have used "Corona Dope" by GC Electronics for such purposes. It's available from
http://www.tubesandmore.com/ and other suppliers.
You also want to make sure there are no sharp points -- clipped lead ends, solder tails, etc. -- on such joints.
If the arcing source is not immediately obvious, a plastic or rubber listening tube held to your ear may help locate it.
It's possible the CRT itself has a problem, but I wouldn't mess with its base until you had eliminated other possibilities.
Don't run the TV for long periods when it is arcing.
