I've been running DCS for ten years without any TIU issues. Today I had to reset my 10 year old TIU to restore signal. After a routine power up, I had trouble recognizing engines and the signal strength was near 0. It took a while for me to determine it was the TIU. A TIU reset appears to have fixed it for now.
Anyone have this problem? Hopefully I will be better prepared the next time.
