First thing I would do is reinstall the original module and see if you can get back to where it was. If it acts dead like the new board, then something else happened coincidentally. If the original board runs with the shutdown and motorboating, pull that dual section PC mount electro and check it, or better yet just replace it. That cap causes all sorts of mischief including damaging the start transistors on that sub board I mentioned earlier.
On Zenith modules, the suffix is critical. I used to have all those boards memorized, but whereas a 9-181-01 might sub the 9-181, the 9-181-02 might not, but the -03 might!
Our local Zenith distributor (Plymouth Electric NH CT) used to mail us cheat sheets that had all the modules listed with the suffixes that would interchange. Saved a lot of time and trouble. All that stuff I tossed out twenty or more years ago.

Well, good news, sort of..... I had the same idea myself, put the old board in to see if she will motorboat. Well, she did a ittle but I got her up and running, right now the old girl is playing Bonanza. I still have the same old issues with the picture with a red tint and raster lines on the right side of the pic from time to time, sometimes it clear, sometimes not, it does look a little washed out on the right. The new board I have is a 9-181 main board, I put the chips and MOSFETS in but nothing there but the old board still works with these issues. There was time she would run for 5 minutes or less and cut off, but she's been going for over 30 minutes now. Still I'll power her down soon until I can fix her properly or find someone to help me. BTW, the old board is a 9-181-02. Seeing that I was able to get her going, sort of, I feel proud of myself. at least I got it back to where it was.
