CRT experiencing blue flickering.

[iOutatime]

So after adjusting my VGA to DVI-I connection, the blue artifacting seemed to disappear. Shortly after, I tried increasing my CRT's refresh rate and found out about 1/2 an hour into use, it started to buzz so I reverted back to 60Hz and (although it didn't remove the noise entirely) it made it barely audible.

Now I went to sit down at my desk and bumped the table to see the worst thing imaginable. I saw my entire image warp for the briefest moment. I lightly banged my fist on the desk and kept seeing it reappear. After a quick power down and rest, I booted the CRT back up and it was gone. Although I was quickly greeted with the blue artifacting from before, which leads me to believe that problem was something to do with the CRT internally.

Everyday there seems to be something new to this CRT. I've only had it for a few months and I brought it to have a CRT (+ it matches my retro setup perfectly). I'd hate to see all the cleaning and elbow grease I put into it go to waste. If anyone can help fix these issues, please do! Thank you.
