Here's this afternoon's FPV adventures: Tested my FPV screen in my office - all working fine. Take the s900 into the garden, switch it on - no image just white screen. Fiddle with camera settings, power up several times, try different power up routines - nothing. Oh well, I decide to do a hover test anyway. I take off and a few seconds later the camera view pops up on the screen, and apart from the odd moment when it disappears for a couple of seconds (i.e. not a typical fuzzy image from poor reception) stays on for the full flight. I take it all back into my office and the image is intermittent, so I poke all the wires in case there's a loose connection, but it stays intermittent and doesn't really coincide with my prodding. I try a spare video transmitter - no image just the white screen again. I switch back to original VTX and get an image. I try flicking through the camera modes but the image locks (but on the camera it's normal). I now have a locked image on my Black Pearl screen. I turn off the camera, and I STILL have the locked image on screen despite the camera being completely turned off. It only goes when I power down the s900. What's going on? :-(
