Hello, I have 2(Two) units and while changing Modes, I fly Mode 1 on right stick, power & Aer. Closing up the rear of the TX heard a ":Phut" sound, removed the back & reinstalled. Now in my display window top right corner I get an "ERR" sign and no blue transmit flashing light. My red light flashes, whereas it should be steady, with a flashing blue. It seems I should send the Tx in for repair, I paid $150.00 for it second hand and it was very good until I buggered it up. Please your thoughts on what to do, can I reprogram it? I am an ex Aircraft Tech & hold Elect licences.
Thanks, NeilT162
