Every third or fourth time I turn on my highbeams, the player goes into standby, then start up with the low-voltage (battery) icon in the upper lefthand corner. It also happens when doing some wide turns or using on the indicators. Note that I have two MK2s and on the other one, nothing like that happens. It also doesn't happen when plugged in AC. Does anyone have an idea of what is wrong with it? Maybe some soldering is bad inside? Or the connector is loose?
