| ggherold@gmail.com: Apr 11 07:07PM -0700 Hi all, My daughters ~3yro computer wouldn't boot... no hard drive. I took her my lap top and brought it home.. cracking open I found no hard drive, but a scandisk thingie. I took it out of the connector, some of the gold plated contacts were corroded (or worn?) It's about a 1"x3" pcb, connector on one end and flat head screw into 1/2 plated hole on the other. The connector was 'sprung' such that the screw in the back was needed to hold it down. (Is that done on purpose?) And I assume the plating around the 1/2 hole at the end is for grounding. Anyway, on several of the gold plated contacts the gold was almost all gone, leaving corroded copper. I think all the 'corroded' pins were on the top. I cleaned it with IPA and put it back in.. same problem. Ideas? Can I try a simple tinning of the contacts? or something else? George H. |

If a switch should open but doesn't, another monitoring switch shorts the power feed (via a resistor) which blows the main fuse. 2 series switches without monitoring were used in the 1970s. I've seen much worse in historic machines, I remember one that continued cooking with the door part way open. > NT I saw an interesting very old Moulinex one which seemed to have a fairly loose door, but when it started cooking, an electromagnet pulled the door very tightly onto the oven. Before I tried it, I expected it to be very leaky but it was one of the least leaky I tested. |
