clifhanger Posted June 21, 2020 Share Posted June 21, 2020 (edited) Hi All, I have an 1040STe that is displaying 33 bombs. long story is I had it sitting unused for years and known to be working. However, powered it up the other day and the PSU burnt out in front of me. I replaced the PSU with a new one. It now powers up but displayes 33 bombs and power cycles every 5 seconds or so. I have looked at all the other components and nothing else seemed damaged or charred. I have also swapped the memory with known good sticks. Can anyone suggest what might be going on and where to start looking for issues? Edited June 21, 2020 by clifhanger Quote Link to comment Share on other sites More sharing options...
ParanoidLittleMan Posted June 21, 2020 Share Posted June 21, 2020 When PSU burns like that, usually there is overvoltage, so some chips are damaged/broken too, most likely. Quote Link to comment Share on other sites More sharing options...
