| IIfx click then nothing | |
| Posted by: Johnnya101 on 2022-04-04 15:50:01 Got my recapped PSU back. Put it in my IIfx which hasn't been started for a couple years, press start key... Click. Had new batteries installed a few years ago. Checked them now, the right one measures 1.6 volts and the left is 3. Guessing this is just a battery issue? Nothing turns on, it clicked once and won't do it again. No power led, no fan, nothing. Don't have any spares on hand so I'll have to order them. Also, the only nubus video card I have currently is a toby. Will a 3 resolution vga adapter work with that? | |

| Posted by: Johnnya101 on 2022-04-05 06:00:34 Removed the battery and tested the voltage. Reads 4.5 ish. Threw in a new battery I found. Quiet click then nothing. Power button on the back doesn't do anything. Logic board was working last time and is fully recapped. Startup circuit was patched. Still have new batteries on order, but this doesn't seem like a battery problem at this point. Power supply? It was just recapped by Amiga of Rochester, and was tested and worked. I will note that this supply came from my IIx, because he redid this one first, but both are interchangeable. | |
| Posted by: unity on 2022-04-05 18:10:15 And... did you try jump starting it? | |
| Posted by: joshc on 2022-04-05 23:02:39 Yeah, try a jump start: Sounds like a problem with the startup circuit, but jump starting will verify if that's the case or not. IIfx startup schematic:  | |

Posted by: Amiga of Rochester on 2022-04-26 09:26:16Problem probably found. Tom from Amiga misread some caps...As I believe in full transparency, yes I absolutely did. Two 10,000uf caps I misread as 1000. I am remedying the issue and have appropriate values on order. Thank you for your understanding John and if we're lucky this fixes your board issue...which I might test with this recapped PSU I just did for you. | |

| Posted by: LaPorta on 2022-05-27 18:32:28 Glad it is up and running! What are you going to put in this thing? | |
Posted by: Johnnya101 on 2022-05-28 03:51:57Glad it is up and running! What are you going to put in this thing?Got a SuperMac Thunder IIgx, Radius PrecisionColor Pro XK, RasterOps image processing accelerator, Radius image processing accelerator, an ethernet card, maxed ram, dual floppies, and an scsi2sd. Hope to do some Photoshop things with it, some aftereffects, etc. with dual monitors. Currently installed 7.5.3 just because it's easier to get networking going so I can transfer some stuff on it, then maybe I'll put 6.0.8 or 7.1.1 on it too. | |
