Mini OSD issue

Hi, I have a problem with miniOSD card , I installed  in my quadrocopter and everything worked correctly, but after two test flights have been surprised to no  image in the monitor. I checked all connections ,but no sign to start again,  al the power LEDs light on, and the data LED flashes but nothing on screen, 5V voltage the is correct . I connected directly  transmitter  with video camera  and everything is ok, the telemetri works corect  on the same port,. Does anyone have an idea about this problem?

  • I had the same problem sounds that your MAX7456 chip is fried. That board controls the osd video and character portion. I send it back or replace the SMD chip.
