Have someone seen this problem before? I´m working with 3 PV1000 plus (connected by Ethernet), couple weeks ago, I´ve installed a screensaver using a 1784 cf64 flashmemory with the company´s logo. The background of this logo was white, and after same power outage or a power off/on, the background of each PV gots black. I´ve tryed to make new downloads, but every time the problem happens.

If someone wanna see, the logo file is attached.

Did the screen saver worked with the white background before power cycle?
My understanding on screen savers for the + model is that the lower left pixel of your bitmap is used for transparentcy. If any part of your bitmap matches the lower left pixel's color, that part of the bitmap will be transparent (not visible - dark) on the screen.
