CRT (Makvision) image is a large bluish blob. Dead, or repairable?

Zebidee:

May as well replace them with new then. If you have to order them, then maybe grab a decent solder sucker as well. I don't like the wick either but sometimes there is no other choice. Flux helps.

You may as well prepare to check out all the electrolytic caps while you are in there - they are a common failure point and can deteriorate over time. Caps going bad can be hard to detect, and you have to remove them to test (unless you have an ESR meter). So lots of people will just grab a cap kit and do the whole lot at once every 5-10 years or so.

Baldbull:

Where do people get components on the cheap?  Is EBay the only real option?

Zebidee:

People get stuff all over. Digikey, Mouser, RS etc. are some of the better suppliers. There is also ebay Aliexpress and other online markets of course, quality variable as you'd expect. There is a stickied thread here for capkits.

You can also get cap kits from various arcade parts vendors.

Baldbull:

Desoldered blue pin from socket.... no change.

Any thoughts on where the issue could be at this point?  Desoldered the blue gun pin and no change.  Where's all this blue coming from?  Could there be some kind of short in the neck tube?
