I've replaced 2 for burn-in, 1 was replaced for those screen marks that could not be removed, hence I am on the 4th currently after 3 replacements. The next replacement under warranty will probably be for something defective.
Probably
Were any of your replacements refurbed panels or brand new?
I’ve had one replacement back in Sept and thankfully it was brand new unopened in the proper box packaging you’d expect as a new purchase.
This was after they were telling me the replacements they send out were refurbished panels. A friend of mine received a refurbished panel and was packaged in an unmarked box etc
I was surprised I received a brand new panel, with the latest firmware at the time, especially as they stopped selling the DW quite some time ago now.
