Hi when I turn on my mvh-300, the display turns on just for a moment and the turns off.Then I have to wait for a few seconds and press display button twice, the screen turns on then.All of the buttons and sounds works when the display is off.
What is the problem?
Could it be solved by pressing the microprocessor button?
