specific problems landing lights B747-400/F

[Guest alex737ng]

Hi guys,I fly for a VA Turkish Airlines. They use a recorder to track the flights and log them. To start a flight with the recorder you have to switch on the beacon/anti collission lights.I use also the pmdg NG series and when i switch on the beacon lights and start the recorder it starts to record. How it is supposed to do.But when i do that when is use the B747-400/F i get the message to switch on the beacon lights. But they are ON!!I did some research and asked on a turkish forum about my problem.They assumed to load the 747 in a dark/cold cockpit and hit the L key. it would turn all the lights on and off. And then it should work.When i do that on the 747 it will only flip the landing lights, runway turnoff lights and the taxi light. On the NG series however it does flip ALL the lights. Does anyone know how i can get to flip all the lights at the B747???thanks in advance.Best Regards,Alex Alblas

It doesn't start when you flip position lights manually on the overhead panel?
