Received my 430W back from Garmin on Monday. Current cost is still $1200, plus shipping. As Oldguy said, the thing looks brand new
Bad news is that when I put it in today, while it now boots up properly, it pretty much fails the CDI test
Both needles only deflect about 1 1/2 dots (no where near 1/2 scale), the heading is 7 degrees off, and the VLOC/GPS indicator seems pretty dim with the plane inside my hangar; not sure I'd see it in full daylight. Before the 430W failed the CDI was not even 1 degree off, and showed proper 1/2 scale deflection on both needles. Not as sure about the previous brightness of the GPS/VLOC indicators. One more thing, after hitting 'OK' on the CDI test screen the vertical course needle doesn't center; maybe a needle width off, or a little more (no GPS/VOR signal). It is nearly perfectly centered when the power is off.
Pretty disappointed, but thought I'd post here to see if anyone has seen this issue and knows the cause. Otherwise, it's back to the shop (which hopefully can confirm this new failure) before it goes back to Garmin...damn well better be under some kind of warranty. A little worried since I didn't see anything about warranty on the paperwork.
The paperwork that came back merely said they confirmed the dead screen and replaced the 'main board.' Not very useful, and no mention of possible cause. They, of course, stated it passed all checks/tests.
