SV-D1000 smoked

[rfsolutions]

Updating the software, running on batteries only, updating software after test flight prior to leaving for KOSH. PFD smoked! Anyone else ever have one completely Smoke? It tripped the breaker and had the typical distinct burned smell. Makes me rethink using this stuff in an IFR platform. Gonna miss airventure this year! :'(

Test flight for what? . . :-?

Marv, I feel your pain re OSH & the Dynon issue.

This is the first time I've heard of any screen being 'smoked' due to a manufacturing fault, & ive done a lot of installs. Not saying it can't happen but it'll be easy for Dynon to see what caused the problem with your unit.
Hopefully the result is not too painful.

Sounds like a wire shorted and popped the breaker, which likely saved the Dynon screen.

Yeah. I'd try turning on the SV with the backup battery (holding button one) to see if it was just a wire.

The pfd is smoked. Moved it to the right side to feed the ems data and popped the breaker on that side and let more factory installed smoke out. I was receiving several communications errors from xpndr, roll & pitch servos, etc. after the pfd popped & swapped positions everything back to normal. Screen was dying and then died. Dynon being champs, have one waiting in KOSH.

Please get an answer as to root cause for this and post it here once Dynon has a look at it. This is very unusual.

A friend had a similar problem with his 430W a few years back, during early flight test. Turned out to be a tiny piece of metal swarf that had dropped into the 430 during aircraft construction (so not a failure of the box at all). A good reminder to protect electronics from FOD during building or maintenance.

I'd be surprised if this wasn't something similar...but then again, who knows? Let us know the outcome, please.

Glad to post the failure cause if they share it with me!
