RCA XL-100 ColorTrak console picture issue

[VHFUHF]

Hello all,
After years of lurking I finally decided to make an account and post a thread here in hopes of some tips/assistance. I recently rescued a 1976 RCA ColorTrak XL-100 Console set that a gentleman in the suburbs was trying to get rid of. He claimed the set powered on normally, but hasn’t really been used in years. When I went to test it out, I was so excited when I heard it spring to life. Alas, the CRT never fully powered on. The top half was lit up with green and red lines (not even the typical ‘snow’) and a white line formed just below the middle of the CRT and the bottom portion was black. When the guy saw that he was as disappointed as I was since it had apparently worked fully a day prior. He let me take it for free which was nice, since cosmetically the set is in immaculate condition. I have a feeling there’s at least one bad cap, but I haven’t cracked it open yet to investigate. That’s my project for tonight (stay tuned).
Now perhaps I haven’t been digging in the right places, but I haven’t had much luck finding the model that I have online, let alone finding data or schematics for it. I wouldn’t say I’m a total novice when it comes to old sets like this, but I could definitely use some guidance as to where to begin troubleshooting. I’ll start by cleaning the chassis out once I get home, since by the looks of it it hasn’t been cleaned or serviced for probably a few decades. I attached a picture of the front of the set and the manufacturer info, and I’ll post some more updated pics once I pop the back panel off later on.
