UPDATE NOVEMBER 2024: Based on comments received here and on YouTube, Pioneer is no longer honoring repairs for this condition when out-of-warranty. That is a great disappointment considering Pioneer has previously admitted the problem was widespread and a manufacturing defect on their end. This means that many owners of their defective head units from 2020-2022 will be out of luck when their sets start showing these common symptoms, if they haven't already.
If you purchased a Pioneer head unit during the covid years of 2020-2022 (DHT-160, DMH-1770NEX, AVH-X2800BS or others), you might find it is starting to fail with a white screen of death. The symptoms will start showing up when you start the vehicle and become more persistent as time goes on. You will get a bright white screen sometimes with vertical lines through it or other major defects including a lack of touch interactivity.
