Hey!

I would add two mini-switches betwenn 3s lipo and led-stripes and the camera-setup (standard ccd, video-tx and minimosd). At the miniosd i've take the three solder-points: pal and the two to use the apm-voltage to power up. The minimosd was connected to the oilpanshield and ccd-camera and video-tx was connected (only gnd and videosignal) to the osd.

At this configuration i reversed the powercabel (+/gnd) at the new switch stupidly. By power-on the minimosd smokes. :/ One of the chip at minimosd becomes hot but the leds are lightning normal. Now all esc beeps at power up and some motors runs by rc-throttle without arming. The esc beeps also, after i've disconnected the minimosd from the rx/tx-port.

I think the osd is broken - no problem. How can I check, which board are broken: ardupilot and/or oilpan?

I can connect with the apm planner. I've entered "setup" and "motors" at the terminal. Only a few motors spins up.

My question: Must i bought a new oilpanshield, a new ardupilot mega, both boards or should i buy a new apm 2 board? The minimosd board must also be new.

Thanks for your tips

Best regards from germany - sorry about my english, but in german boards are no...
