C310 avionics black and not booting [PMS and TDS not installed]

[jurgen.born]

Hi! I have a problem where the only GPS working is the Asobo GNS530. The PMS50 GTN750 and TDS GTN750Xi will not work (the screens stay blank) when Avionics power is turned on. The buttons light up though. Also the HSI has the red NAV warning flag always shown. I did everything exactly as shown in the checklist.

Do you actually own the PNS and TDS? You know those are seperate addons you need to have installed in order for them to work?

I did not know that. Thank you very much!

Take note that there is a free version of the PMS GTN750 available: highly recommended!

I'm having the same problem and I have the pms50 GTN750 and the two small glass gauges that you can replace the two steam gauges from the tablet stopped working also. I removed everything from the community folder except the C310 and the GTN750 and it still didn't work.
Any other ideas would be greatly appreciated.
I did install new Radeon drivers lately, could that be the problem?

The G5 gauges are stock MSFS. Are you positive you have the latest version of PMS software and that it's installed properly?

I have the same issue as Jurgen.born and I do have the pay version of tds gtnxi 750 and have not found a solution for this yet. Has anyone figured out why this happens.

His issue was because the software was not installed.

Have you made sure your TDS software is the newest version? The only other complaint of it not working was because of out of date software. Also until it gets updated for the SP you cant use both the TDS and PMS as it causes issues with the touchscreen etc.
