I was prepping a QMX for loan to a friend in a nursing facility and foolishly used a wall wart labeled, 9 VDC @ 300 mA to power it as it only needed power for receive. I had opened the QMX to measure the voltage at the jack which read 15 V. Before I could pull the plug it died.

So what's the probable damaged part and how do I test it?

Thanks,
