I am pretty new to this, and built my OpenROV during the workshop in Oslo in December. It has the frame and motors fron 2.6 and the control board of the 2.7. It has been sitting unused since then and I just got started on it again yesterday. So before I went out I powered it up and everything worked fine - funnily the video feed did not work on my mac in Firefox, but in Safari I got both video feed and controls.
I then took the ROV outside to do a water test, and it would not boot up. I got the first beeps, but not the second - and no feed from the ROV. After a couple of minutes I get flashing main LEDs on the ROV. I noticed then that the middle orange light on the topside adapter was out and pressed the reset button. After that I get all 3 solid lights but still the same result. The first beeps only and after a few minutes flashing LEDs on the ROV. I have checked the cable connections but everything seems fine.
I would appreciate any pointers to help me on the way to getting this thing wet again. The cod are spawning in the Lofoten islands in northern Norway and are eagerly awaiting my OpenROV at 70m depth
