Well, a bit of a bummer this morning. After several hours of playing last night with a perfect picture. I turn it on this morning and now i have no vertical.
I've opened up the case, checked the yoke and it is ok. The set says made in Taiwan ROC but upon examining the components are mostly made by Matsushita, the crt is a 150chb22, the vertical chip is a an5532 chip. I can't find a FCC number as such but there are 2 paper stickers with a serial number 4349 and a sticker that says 7A7. Nothing looks burnt inside i can turn it off and on and see a quickly decaying raster before it becomes a line. Par for the course from radio shack i quess. Kinda shocking that this set cost $320 back in 1988.
