Sometimes (like today) the FMC of my 737NG remains cold and dark after switching the master battery on. All displays are lit, but not the FMC. It doesnot matter if I use ground power, the APU generator of even start the engines. Can anybody help?Hans HartveltThe Netherlands

Yes sir, standby power is the standard setting. I also tried other settings of this knob, but it doesnot help. I can see that the dark screen lights up a little when I engage the instrument lighting, so you should say that there is current to the FMC, but no text appears.

As a learning point for other simmers:I recently reinstalled FS9.1 with all its components. I had a problem reinstalling the 737NG due to an error message related with the font lucon.ttf. So I removed this font and the installation was a piece of cake. But since there was no text visible on the FMC I remembered this installation problem and thought that the FMC might use this font. So I removed the font back and YES !!!

Make sure your APU bleed switch is "ON".Hope this helps.Alex
