Fruit Machine Chat

Hi Guys, I changed my bottom touchscreen as it was faulty, now i get no signal on the bottom screen and test mode in the top screen.
The machine will not start although the pc starts and the note acceptor cycles.

Can anyone point me in the right direction?

At no time did i have the machine switched on with the monitor removed.

do you have power to both monitors? i.e green light on the monitors at the back?

I got it sorted. A cap was bulging on the pc unit so i replaced it and all is working now.
