emax II display/ps whine

2012-11-26 by plus_321

Hi,

I am trying to put another oled display in my emax II, but after taking out the old one I hear a whine coming from the screen.  I unsoldered the inverter (VR1?) and now I still hear a whine coming from the power supply.  Is there anything I can do?

Thanks,
Chase
