| Radius Pivot DB-15 to DB-9 pinout? | |
Posted by: Kouzui on 2026-04-20 15:43:53I'm working on opening it, but the inside is pretty intricate. It's slow going as I try to figure out and document were everything goes. Did you have any resources that helped you take it apart?I don't think I found anything resembling a teardown when I did it. I just kept going at all the screws I found until it was apart. One thing is that I think you don't need to take the base off the monitor in order to take the CRT out. I found that out after, but I think the screws in the back were all that was necessary to actually get it out. Also, here's the list of the capacitors I bought:  | |

| Posted by: jasonfortheworld on 2026-04-21 09:16:23 Just realized there are 4 different model number for the monochrome Pivot Display. I have the second revision (model 0276) while yours is the first. The boards looks mostly identical except for the neck board which has mlre stuff populating the PCB. I'll probably need to do my own cap check when I have some extra free time. But your other work is very helpful for me to cross reference. When I'm done I'll make a list for my model and share it. But you weren't kidding about the RF shielding. It was soldered to the neck board and I had to undo it. Not the easier thing to take apart, but the inside is really robust. I guess it had to be if it was going to constantly be rotated. | |
