Sweet, just the flyback :?:

I replaced the HOT too as a precaution.

Certainly a good call to replace the HOT also.

Nice work!!

So a quick note on the tools i used...

I made a discharge tool with this

and

https://www.amazon.co.uk/gp/product/B099MJYV78

And for setting the screen and focus i found a plastic chop stick and shaved the end down to a screw driver bit so i could adjust it without having anything conductive in the monitor... particularly for this monitor as your tool needs to go past the high voltage wires while you adjust.

Replacing a flyback is as easy as it is dangerous. And it is VERY easy.

When I was kid I tried to replace the one of our family TV in a fashion I could only described as "YOLO"

Of course I touched the high voltage (with the TV plugged off mercifully) and of course the discharge went through me.

It's not the buzz you get when you accidently touch 220V. It's more like getting hit by a truck. I must have released half a liter of sweat in a quarter of a second, I remember distinctly being all wet, covered in cold sweat all over.

Since then whenever I replaced a flyback on a 1083 or 1084 I never, ever dared to do the "grounded screwdriver below the suction pad" trick. I just let it sit for litteral months (as in, more than half a year) before daring to open. And I adjust the focus afterward with a long bamboo stick and a webcam, which is very clumsy and takes forever.

I replaced flyback on my Atari and simple discharge with screwdriver and cable worked superb, Thanks to good people on this forum I was able to tune it later and very happy with the result.

While we are on the topic, I also need to replace the flyback of my IIGS monitor (no reference number on it except "12 inch Apple IIGS color monitor", I assume the only one ever sold bundled during the IIGS short lifespan ?), I've never been able to find a replacement flyback, there isn't any label on the flyback itself.

Any tips would be appreciated

Same problem here, but with a Commodore 1701 monitor. Significantly different flyback to the 1702; it actually looks like "2" flybacks.

Managed to find CJ26107 and CJ30635. I think it is actually 2 flybacks.
