Just stay away from the flyback! A couple tens of thousands of volts is not fun but a couple hundred volts ain’t no big whoop! 😂

Here’s the service manual incase you don’t have: https://www.applerepairmanuals.com/the_manuals_are_in_here/AppleColor_High_Res_RGB_Mon.pdf

H-Stat and V-Stat. Bottom two left pots. After putting it all back together. My wheels started spinning in my head so of course I had to crack it open again and do a thorough adjustment based on the service manual. I downloaded the Display Service Utility as well. But first turned off all...

Yeah an easy fix. For once.

Could be before I cleaned it. Also it’s very hard to take a decent photo. I have to capture video and then find a frame that’s not out of sync with the camera.

Thanks for the help guys! Now I have a display I can use to fix these IICX boards from hell 😂 🤦‍♂️

Couple more pics to show color. The text is just slightly a little blurry but that may be normal and my modern 2023 eyes are just spoiled now with retina displays.

I think I’ve got it pretty dialed in now! One of the horizontal control pots is cracked and some pots were slammed all the way to one end so I think someone’s been in here before.

I’ve already got it a million times better by adjusting those. Now I just need to get the background to be black.

Ive got the casing off, Which Pot are you referring to as being the cutoff though? the manual mentions several:

Yeah I saw your warning in that thread as well that you weren’t sure which monitor was because you were doing two of them. Mine is the M1297.

Would the caps causing the bad convergence be on the video color (b) board you think? Or more likely the deflections board (d) that has the most caps.

Ahh ok good to know. Maybe I can ESR check the caps in circuit?

Thanks for the link and wow that’s a lot of caps!

Thanks. Yeah I just read similar instructions i the service manual. I will open it up tomorrow. I want to re-cap it as well. Unfortunately there’s no cap kits that I can find on console5 or elsewhere so I’ll have to build my own BOM and order them. I did find the Display Service Utility...

Took some more photos after changing it to the primary display. Seems like there’s 3 issues. 1) it’s showing the horizontal retrace lines 2) the r g and b convergence is off 3) there’s hardly any brightness control. The darkest black is light gray. *** after looking at the service manual ...

I got a chance to hook it back up again and you were right it wasn’t mirroring the screen. Once I dragged a window in there it showed up. So there IS an image, it’s just very washed out and it’s got those diagonal horizontal retrace lines in it. Caps??

Good point I see some color on the edges of the screen. I’ll try mirroring. And moving windows around.

Well I’m back at it with a repaired PowerBook 180 and video cable so I can test. The bad news. No picture. The good news it’s filling the screen with white so it’s doing something. And it’s showing up on the Mac. Video and photos attached:

All original but re-capped / repaired.
