@ AlexS16:

Sorry I forgot this thread. It looks you purchased the assembled version. In this case we will replace it if it doesn't work. Please contact JYEtech at jyetech@163.com.

If you want to do troubleshooting you can try this:

1 ) Remove the analog board from the main board and see if you can get trace at the middle of screen. If you do the problem is with the analog board.

2 ) Connect analog board back with the main board and measure voltages at various test points by against the manual. Please post your measurements.
