ATU-100 Stuck in Bypass #107

Open Rimon105 opened 1 year ago

Rimon105 commented 1 year ago

Hello all, i have been using my ATU-100 for the past couple of months with no issues. however, 2 weeks ago it stopped tuning. the display shows its in bypass mode and none of the buttons are changing it. i used test mode to confirm the buttons work but when its booted normally, it again goes into bypass. this was a kit but i have gone back over my solder joints already and double checked my windings (ill triple check soon). Any sugestions?

Hi. I would check a voltage on the buttons.

Hello, i checked the voltage across the buttons. Bypass is .01v, auto is 3.8v, and tune is 4.8v.

Bypass is shorted. Check the connection.
