A problem has come up with my main panel during testing and configuring, that suddenly the screen blacked out after a while of operation. this would be not a good experience in flight, That’s why I have a backup panel but still it is not very desired experience. After a long battle to get in contact with our local distributer of MGL which was very useless, I contacted the US branch and got prompt responses next day and help to what the problem is and how I could fix it. After a few more emails it was clear I had only to change 3 diode for the back light of the screen control cost on material $20 and a few minutes of soldering, done. Extensive testing for hours showed no problems anymore.
