| SE/30 rebooting problem with screenshot | |
| Posted by: macclassic on 2020-01-03 06:25:08 My SE/30 has now started rebooting by itself in a vicious loop, and "extensions off" makes no difference. On a couple of switch on's it also displayed the shown pattern for a couple of seconds, which then disappears before it tries to boot?  | |
| Posted by: dochilli on 2020-01-03 06:46:40 Check the voltage of the AB. May me low voltages. Must be 12 and 5 V. Voltages can be checked at the floppy port. Is the logic board recapped? Check the reset button. Can be the cause, if it is Reseat Rom and Ram. | |
| Posted by: macclassic on 2020-01-03 11:09:44 Yes it's been recapped. But I've just checked the voltages at the port and the 12V is reading 12.72v and the 5v is fluctuating between 4.59 and 4.62v :-( | |
| Posted by: Bolle on 2020-01-03 11:41:49 That’s right on the edge of when one of the Sony soundchips resets the system. The Sony PSU is easy to recap, that’s what I would start with. I think there’s even a list of the needed caps around here somewhere... | |
Posted by: jessenator on 2020-01-03 11:56:42list of the needed caps around here somewhereI just keep snagging the one on JDW's re-capping video 🙂 https://docs.google.com/spreadsheets/d/18X-EN67lQdZ2crCBAlkHrtqCCoJK6cLw_BkIYdlJvgs/edit#gid=0 | |
| Posted by: macclassic on 2020-01-03 14:25:26 Thanks for the help and assistance in this matter. I've just swapped in a spare power supply producing 4.9v and the problem has gone. The recap will have to wait 🙂 | |
