Re: replaced SMPS cards and the QMX is not detected by win 10 to load the firmware.
|
By increasing the current to 1 A the Qmx turned on for about 10 seconds, it was connected to the PC with win 8 and it was detected, then I smelled a burning smell and I immediately disconnected the voltage, I noticed that the card underneath the SMPTs was a little hot and it didn't turn on anymore.? I hope it can be repaired.? 73 Giuseppe iu8eun
Good evening everyone, today the SMPS cards arrived after almost a month of waiting, the post offices here in Italy work badly, well, this evening I replaced them, no shorts on them, I carefully checked all the soldering and I have no found no problem, I connected the QMX to the PC and it is not detected by win 10 whether powered with 7V or with 8, 9 and 12 V at 500 mA. Would anyone have any suggestions for me to do further tests.? Thank you very much 73 IU8EUN Giuseppe iu8eun
