| darksun9210 Posts:1319 | August 05, 2008, 05:29:00 PM i got that on my A4000T. AT type connectors are ... pants ... i have no idea what kinda current my machine was drawing, but it would do this to a PSU every year or two. suffice to say the machine was fully loaded with cyberstorm accelerator and every video and zorro slot full. if your machine is acting flakey, this is a prime cause. |
| rkauer Posts:3263 | December 21, 2007, 08:44:28 PM Not always! Normally what happens is: one of the pins comes loose. With this the other +5V wires had to supply the current required from the system in an overcharged basis. Then one more comes to fail (due the overcurrent in the connection). What happen next? Yes, one more to fail. Then other and finally all the wire contacts will fail miserably! The solution: check the contacts in a regular basis. Whit the Amiga opened and powered on, touch the connector's surface. If hot, disconnect it and clean the pins. If it not helps, swap the connector for one from another PSU. |

| January 10, 2006, 02:43:19 PM this is what happen if you try to insert the power plugs the wrong way while its powered up... to bad someone must learn the hardway! |

| Dr_Righteous Posts:1345 | August 21, 2005, 01:51:41 AM Damn, now that's what I call a bad day! I hate it when I blow PSUs... The arcing, the smell of burning electrolyte from the capacitors... Barbecued resistors and the lovely smell of charred wire insulation. *shiver* |

| May 09, 2004, 04:01:29 PM Snap, had exactly the same on mine. Got a picture here, but it's not online anymore.. I struggled on with the burnt connectors until the plastic finally crumbled away completely! I replaced just the plastic bits from an old AT PSU, cleaned the metal connectors up, and it's not happened since. I suspect at least part of the problem has been that the original plastic plugs weren't a very good fit. |

| January 28, 2004, 11:00:37 PM Finaly, my picture has appeared (after several months of trying) Quote (thats an AT PSU, btw, not ATX).Ooops!! So it is too! How embarassment! :oops: :oops: (I know it's AT, just wasn't thinking at the time - how do I change the text?) |

| January 28, 2004, 03:50:21 PM Obviously not much redundancy was added when they did the A4000T power calculations. /Patrik |

| January 28, 2004, 11:27:37 AM I was having all sorts of problems with my A1200T/Z4 and I noticed the P8 & P9 connectors were looking slightly yellow here and there. I found that the connection blades inside are very easily fatigued and lose tension on the board pins. This causes overheating as seen in this picture. I stripped each connector down using a narrow probe to unlatch the blade fixtures. Retensioning each blade has fixed the problem permanently, I hope. JaX |
