RVOSD6 constant blue and green lights, DEAD or ALIVE?

One of my good friend of mine gave me this old RVOSD6. He used it a couple of times many years before, but now hi is out of RC buisnies a while. I'm not too experienced with this board yet, so you guys maybe can help me.
When I plug in the aux battery to its pin (3s lipo) the blue and green LED-s are both lights up constantly on the main board. I suppose it's a good sign although the board not gives any other lifesign. The camera is plugged to video in but video out remains completely black. Although I can get composite signal from the video in S pin so the camera gets power and gives image. I asked my friend if he has ever experienced this before, but he doesn't have a clue either. I can't find any documentation about the indicator led functions. I suppose green is for power on, but then blue should be some I/O indicator so I have a bad feeling about it. Is RVOSD 6 has some state of lockup or disable function which can cause this. If someone has some idea about this, please let me know.

The blue and green LEDs show that the PSU is working and providing output on the video in/out ports.

If you confirmed that you have a good video signal going into the RVOSD and get no video out it usually means that the RVOSD video board is toast. This is definitely a hardware problem.

The only thing to check is a different camera and make sure its outputting a good video signal into RVOSD video in.
