Never assume anything. My SV 1000 was working fine and I had run the test and determined my unit would need the updated circuit board eventually. About two weeks ago on turn on the display had a very slow flicker like power surges were occurring and then when I changed the brightness setting, I suddenly got flashing red Xs on the ADHARS and EMS displays. Map was normal. I manually shut it down and assumed it was being caused by the circuit board that needed to be replaced. It would not restart and I got a black screen. I returned the unit to Dynon and they had it back to me in 6 days. Outstanding:
Now the rest of the story: On installing the SV I hooked up everything and turned it on and got nothing. A black screen. On investigation, I discovered a blown fuse. Replaced and turned it on again. Display had just come on and was starting to do the setup required when it shut down on it own. Fuse was blown again. Oh Oh. Replaced and fuse and it blew immediately. Call to Dynon techs confirmed it worked before they returned to me on the bench so:
Bottom line Tech support said to try to power just from B/U battery. It wouldn't power up so I disconnected the B/U battery and it booted normally on ships battery. No more blown fuses. Although my unit needed the new board the failure I experienced was caused by the B/U battery failing, not the circuit board problem. New battery will be on the way soon after I pull the old one. So again don't assume something until you investigate. Had I bothered to look at the C/B panel, I would have noticed the little LED in the fuse on but I just assumed it was the unit failing from the need for the new board. Tech support was timely once I was smart enough to call them.
