What factors would prevent the CRT screen in the PMDG to display? Someone I'm trying to help is having problems. He's made sure the avionics is on and his other airline add-ons work, he went through a start-up guide I made, and nothing seems to be lighting his CRTs? What could be the potential causes? Thanks in advance.

Chris,One problem that I can think of is that he's been draining the batteries by flying without the generators engaged. Check the AC/DC metering display on the overhead and make sure your BAT and BAT BUS voltage is above 22V. If this condition is allowed to escalate through saving your flights you will eventually drain the batteries and loose a lot of equipment on the way. Check the manual, chapter 07, pages 7-25 yto 7-27 on how to read the metering panel.Hope it helps,

Okay thanks.

Check in FSUIP that you have checked the box that says something like 'Extended battery Life' - make sure you choose 'indefinate' or something like that.

Why cheat? ;-)
