Your arcing could be the silver mica disease in one of the IF cans. Some have the mica caps in the base of the can and can fail, causing arcing, static etc. They can be cut our/disconnected and regular micas soldered in. I oft do TV's in steps against the advice of some. Makes it easier to find any errors. I usually start with the power supply, then horizontal, vertical and sound in that order. Keep the brightness and contrast turned way down just in case you power up with no vertical sweep, and in some cases, no sweep at all. It may save you burning a line or spot on your tube.
