Posted by: ried on 2022-12-20 09:12:21 We're going to Save the Molar Macs! 😀 Now I've gone ahead and jinxed it.
Posted by: ried on 2022-12-20 13:14:22 Solved. Even with my shoddy soldering skills, I was able to fix the cracks at the power supply->motherboard connector and it's once again working as normal. It's been running for an hour, struggling mightily with Quake III Arena 😆 Thank you, everyone, for helping to solve this. Hope it helps other Molar Mac owners, too!
Posted by: 3lectr1cPPC on 2022-12-20 13:27:23 Do we normally pin important threads over here? There used to be a bunch last year but they were unpinned mostly. If so, this one definitely should be!
Posted by: AwkwardPotato on 2022-12-20 13:55:46 Yay! Probably wouldn't hurt to reflow the joints on other stressed components too just to avoid future headaches... connectors, transformers, anything with a heatsink. Same conventional wisdom you hear for Compact Macs. Do we normally pin important threads over here? There used to be a bunch last year but they were unpinned mostly. If so, this one definitely should be! Agreed, since this seems to be a surprisingly common issue.
Posted by: Torbar on 2022-12-20 14:30:57 Awesome to see that helped, and now I definitely need to reflow mine! funny that it ended up being a relatively simple thing that all of us typically do with compact Macs. Thank you to everyone that helped narrow down this issue, but particular shoutout to AwkwardPotato, and Techknight(who helped me over twitter). Also, a source for NOS flybacks is here(figure cant hurt to post for future people if they need one. Mine was doing the zapping sound thing before replacing it). https://technotronic-dimensions.3dc...-Apple-powermac-Flyback-transformer_p_60.html Slightly different revision, had to bend 2 pins to make it fit in the board, and splice/solder the G2 and focus wires, but it works. (tagging @Unknown_K so they see it, i know you reflowed the solder joints on the PSU, but whenever you get around to it, you can check the -12v wire) Agreed about pinning the thread is probably not a bad idea. Tagging @Cory5412 so he can do it if he agrees
Posted by: Cory5412 on 2022-12-21 10:48:40 When possible, we are no longer pinning new threads. I did a big clean-up of old pins earlier in the year. I would rather not go down that path again, as it makes the forum more difficult to use. We have a wiki - here's the ideas/wishlist thread for articles for it: https://68kmla.org/bb/index.php?threads/wiki-pages-article-ideas.7129/ We can make wiki accounts for more people or if you post here in sufficient detail as to the symptoms, troubleshooting, and fix, someone can write a wiki article and cite this thread as the source. Framing it that way also makes finding the important things significantly faster for anyone who needs that information in the future. (e.g. don't need to wade through a bunch of people proposing a PRAM reset to fix a broken cdrom drive.)
Posted by: 3lectr1cPPC on 2022-12-21 11:15:08 I can make a wiki page on this if people would like that, just would need permission to use the photos from this thread on the cracked joints and the wonky display.
Posted by: ried on 2022-12-21 12:43:03 Works for me.
