While doing some rework, a hot lead fell out of my hand and dropped on the board. A few segments on the display lit up briefly and then an eerie silence. Except for the little map light, nothing works. I've checked the DC voltages on the IC's and voltage regulators and the only voltages I can find out of limit are on U1:
pin 7: 0 and should be 1.4 pin 23: .3 and should be 4.9 pin 25: .5 and should be 5.0 It would appear that the MCU is blown although I can't quite see how these pins could keep the display from working. The hot lead dropped down in the physical between the 3 blue buttons and the MCU. I've verified that the xtal oscillator that drives the MCU is running. Before I order a new MCU, are there any other components that I might have blown due to carelessness that I can check? 72, Clark/WU4B -- View this message in context: http://elecraft.365791.n2.nabble.com/KX1-I-Killed-My-Rig-tp7597836.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
