I also had to redo most of the solder connections on the boards. You could see what a bad soldering job Sony did when they were built. Not enough solder, Easy to break. I actually though about trying to reflow the boards since that would also be good for the ceramic caps, but in the end even touching a ceramic cap to resolder it will reset its value from ageing.

    Maybe these old 1975 color TVs are different than the 80's Sony ones, but I'd always try to save a monitor or tv before giving up.
    Very low emission from the green gun in every Trinitron TV I've worked on in the last decade, which includes every one I've owned. I don't know if this is really inherent to Trinitrons or if I've just been that unlucky.

    I've been looking for a long time. There don't seem to be any round here. Plenty of nice monochrome ones that size, and lots of colour sets just too big to set on top of my ][+ where it sits. But I haven't given up.

    Oversaturation was pretty much the way they all looked back then. That, and they weren't quite in tune. Most people even turned the colour control up too high on their composite monitors. That was what I remember always seeing anyway.
