I picked up my plane with new G5s today. Previously I had a 750 hooked to a MD200-706 and a GNC255 hooked to a GI-106A. I removed the GI-106A and connected the MD200-706 to the CGN255 because the 750 is now connected to the G5. I am either seeing a weird parallax issue, reflection or my MD200-706 needle is vibrating at a high frequency fore and aft. The needle is clear when it is centered, but if I look at it from off-center it gets blurry. It did this with two different VORs. A video is here: http://www.xericdesign.com/archive/CDI-Video.mp4 Is this supposed to be like this? I have had this instrument for just over a year and don't recall it being like this. I got it at last annual in late October 2017. When I dropped off my plane at my shop in late September 2018, it was not like this (at least I don't think so). I just picked it up today and flew it from Portland to Reno. Naturally, it is 6 weeks out of warranty now... except it has been in the shop since before the warranty expired. Thoughts?
