Hi,Don't know if it has anything to do with SP1 for the PMDG 737NGX, but after flying for 15-30 minutes the displays loose the info and only show the blue screen.The knobs/switches then still work.I had this with the last 5 flights since updating the 737NGX.One time the info on the Radio display stayed, while the info on the main displays was gone.When shutting down FSX ( and Linda) the SerialFP text is showing.Help is appriciated.

Gerard,1. Try to click "Reload Lua Engine" in LINDA GUI's side menu (on settings page).2. Try to figure it out at what exact moment do this blank-out is happening. Do you rotate knobs at this moment or what you do else?

Reloading makes no difference ; one time it happens when climbing and another time when flying at cruise altitude.Both without having touched a button/switch for 5-10 minutes.Like I wrote, the buttons/switches keep working, so that's a ghood thing.

Actually, I have no idea, how this could happen. I cannot blank the display even on purpose, so you should test it in same conditions and same period of time with SerialFP2 software to check if it is not a hardware problem. And try the latest LINDA v1.1 - it's more optimized and not sending updates to display constantly as LINDA v1.03. May be it will work better for you.

Make sure windows isn't powering down the USB ports for idle devices, go into windows device manager then right click on all the USB Hub devices listed in the device manager and untick the option that says something like "allow windows to power down this device" in the power management tab, I can't remember the exact wording.

I reinstalled both the 737NGX and Linda and from that moment opn I did not experience it anymore up to now.......
