I have a 5 yr. old 32X Dahua ptz poe camera that has a red hue in color mode, B&W ok, and camera reset is no help. Is there anything I can try myself, as I live in Florida & can't find a repair center anywhere in America. I figure it's a board issue but I don't know if I can get parts anywhere, or even if repair would be too costly to justify doing.. Any help would be greatly appreciated! Thanks in advance
