I picked this TV up from a condo straight out of the '80s a few weeks back. Like Miami Vice '80s! It was awesome. The TV did work for a few minutes when I got it home, but the picture quickly began to distort just before the vertical collapsed. I unplugged it and let it sit for a few weeks until I was ready to make the repair video. At that time, it would no longer get a picture or sound. I could here it get power and the sleep lamp on the front would come on, but I never got snow or static. I resolved that issue by replacing several capacitors, but once it began to power up again, the vertical collapse issue appeared to be intermittent. This failure was traced to the Vertical Deflection area of the board. Although I never saw exactly where the cold solder was, after reflowing the solder in that area, the failure was resolved. Now the tv functions and looks great!
I do not recommend you working on your own tv without an understanding of the potential risks involved.
