Have tried all this fixes for black screen, all cable connectors, new wifi module, all latter stages software and firmware upgrades, cold boot Main Controller ..... To no avail ! One thing, the firmware up grade for the camera 1.3.0g will not load ! Tried different SD cards changed file name ... Nothing ! Stuck on 1.2.5g. When I try to take a pic or video the message " network timed out " comes up on the screen. Seen somewhere that there is a wifi board in the camera that can be the problem ? At this stage I'm thinking strapping a stick of jelly to the P2V+ climbing to 400 feet and BOOM ! That will fix the f***** !!!. Anything Please !
