Hello all...

As some people around here, i'm experiencing pb with my minimosd, latest release...

Everything was working fine.

But for no reason, i can't display any data overlay anymore on my image.

I can see the camera view through the osd, but i 've no information at all.

It may come from the fact that i connected unfortunately the usb in the same time as the osd on my apm... Could that fried my osd ?

I reflashed everything and sent back the charset with a well powered usb port + alim on the other side of the  osd.

All the best,

jerome.

What happens when you disconnect the camera? Do you see the overlay then?

Hello Kieran, 

Thanks for your help.

Nope. If i disconnect the camera, i got nothing at all....

I happened to order a new minimosd. But if i can troubleshot this one i will be quite happy !

I have the same problem

There's a long thread here which has some solutions but I have the same problem still.

Hi.

The max7456 chip is quite fragile. As far as i understand, it can easily be killed by slight voltage differences between the analog and digital grounds (or Vcc) for instance.

I already fried too boards... but it is not very difficult to repair it by replacing the MAX chip (you can order a couple of these chips as  free "samples" on Maxim site). You can find some more details here:
