I'm working on my first restoration project; a Donkey Kong. It has some monitor issues. It has a partial horizontal collapse that I understand I should be able to take care of with a cap-kit.
I posted these questions in another thread, but it got buried.
The image also sporadically "sputters," "clicks" or "sparks." It flickers, there's a bright flash on the screen and there is a crackle type sound. See the video. This was taken before I adjusted the color pots.

After searching the site and getting some advice, I believe my flyback is going bad. Other people have had this problem and the advice was that the flyback was arcing to the chassis/cage/ground. First question, does my assumption seem sound?
I've read that people suggest that you take off the flyback cage and look for the flyback arcing. This can temporarily be fixed by applying silicone gel/caulk to any cracks in the flyback. I understand that this is only a temporary fix and the flyback should eventually be replaced.
Some other questions:
Should I discharge the monitor prior to removing the cage? (I'll of course turn it off and unplug it.)
Any particular type/brand of silicone? Or just like bathtub silicone caulk?
I will eventually replace the flyback I believe. When I do this, are there other parts that should be replaced at the same time? I'll do my cap kit then.
Do all aftermarket flybacks have the 2-part focus assembly like in this guide: http://www.cinelabs.com/sanyo/Sanyo_Install.pdf ? So, do people recommend cutting the cage, like suggested in this guide?
Are any particular aftermarket flybacks better than others?
Anything else that should be kept in mind with flyback replacement?
Thanks all!
