1982 Zenith System 3 Problems

[NowhereMan 1966]

Well, I think my 1982 Zenith needs help, I think a capacitor or two went. First when I try to power her up I get a buzz and if I get her going, she goes for about a few minutes and then shuts off and buzzes. I knew I probably had a funky cap or two, most likely on the 9-186-01 HV board but she still ran. She also had white retrace lines on 2/3rd s of the screen too from time to time. I'm just looking for input but what research I did, basically the 9-186 board needs replaced or worked on. She is a SY2585P model with a 9-181 chassis and 9-186-01 HV board. I've seen 9-186-03 through 10 boards for sale and would like to know if they can fit, I know an 05 or 06 can fit from prior research. Also, what SAMs book should I get, i tried to search with the model number but it isn't listed although I'm sure any SAMs that covers the 9-181 and 9-186 will do. This is my first time digging this deep into the TV so i want do do it right. I know you have to discharge the CRT too, I've seen it done where the TV tech used a screwdriver with a plastic handle (of course) with a wire and 1 meg resistor hooked to the chassis for ground. This is what I can figure but I'm open for advice to people that are pros and more familiar. I would like to keep the old girl going, I know this is a labor of love but it does mean a lot to me as many of you can understand.
