What steps will reproduce the problem?
1. Setup in basic mode and nothing
2. Solder all the jumpers for the APM to power the board (successful power up) 
Still no image
3.

What is the expected output? What do you see instead?
OSD display, Black screen no OSD information

What version of the product are you using? On what operating system?
MinimOSD

Please provide any additional information below.

I just received my MinimOsd and I have a pal camera. I soldered all the pins 
and jumper pads to have the APM 5v provide power to the whole board and the 
camera and transmitter with their own power and ground. When I have the 5v only 
plugged in the whole board lighted up but the chip on the APM side gets pretty 
hot.(is this normal) I also soldered the pal pad on the board. All soldered 
points are clean and perfect not sloppy. The video feed just shows a black 
screen and no data is showing on the screen. I unplug the power to the camera 
and it goes fuzzy. I have the video in the corrected input and outputs. I am at 
a loss what do I need to do to get this working.

Nothing. I believe that MAX7456 Chip is fried because getting nothing and 
resoilder all the pins to see if connection issues. Ardunio chip Atmega328p is 
talking to my programmer and I can program it just won't push video through the 
max7456. Will have send to warranty and have the chip replace.

It sounds to be a hardware issue. Please report this directly to 3DRobotics and 
DIYDrones Store.
