I opened up two more sets that I got from the TV shop and thought about the vertical circuit repair that you did on the Orion.
First set was a 4 or 5 year old 27" Orion with no vertical deflection. I could tell that he changed the vertical IC (LA78041), a cap, and a diode. Who knows if he used the right parts. I put it back together and said I'd tackle it another day.
The second set was a 27" Sylvania (Funai) that was dead with a squealing P/S. Unsoldered the LA78041 and it came up with no vertical deflection. Also found a bad cap. I went through my junk looking for an LA78041 and found everything but what I needed. I'll check the local parts place to see if they have anything. If not, I'll have to order the part, which will tick me off. It's getting so I have to order more and more of what I need because the local parts house does not stock many TV repair parts anymore. The owner told me that TV/radio repair parts were his "bread & butter" 40+ years ago. Now, he said the schools and other commercial interest are the only things keeping him going.
I probably need to order several of these LA78041's as well as some of the other common vertical IC's. Over the past several months, I've fixed many of these "junk brand" TV's and many of them had vertical deflection failures, usually caused by the cheap low grade electrolytic caps used.
