Once you know what pins are bridged together you can consult the schematics to find out where they are located on the PCBs.
## Updating to the latest Github code
It might be that the current portable release is behind the active development tree and your issue was already solved in the meantime.
To update to the latest Github code you can download and extract the current portable release [VXX.X_Portable.zip](https://github.com/sanni/cartreader/releases) and [the latest development tree](https://github.com/sanni/cartreader/archive/refs/heads/master.zip) and then copy all the *.ino files from cartreader-master.zip\cartreader-master\Cart_Reader\ to VXX.X_Portable\Arduino IDE Portable\portable\sketchbook\Cart_Reader\. Then follow the [update guide](https://github.com/sanni/cartreader/wiki/How-to-flash-the-Arduino#to-upload-the-firmware-to-the-cart-reader-please-follow-these-steps).
## Black Screen
If you just get a black screen after turning the OSCR on you can change the output to [Serial Monitor](https://github.com/sanni/cartreader/wiki/Serial-Monitor) to get some additional information.
## Black Screen (Mega2560 Pro receives power)
If you just get a black screen after turning the OSCR on but the Mega Pro LEDs do light up indicating it does have power then you can change the output to [Serial Monitor](https://github.com/sanni/cartreader/wiki/Serial-Monitor) to get some additional information.

## Black Screen (Mega2560 Pro does not receive power)
If the status LED on main PCB lights up but the display stays dark and the LEDs on the Mega Pro 2560 also don't light up then you might have forgotten to solder the J1 jumper on the back of the main PCB.
