DJM-TOUR1

I open a ticket with Alpha Theta over 3 weeks ago due to my touch screen only working on certain areas on my DJM-TOUR1 . They  asked me to reinstall the firmware and if that did not work we will need to go into diagnostic mode. I found the service technical document for my other mixer the DJM-900NX2 but can seem to find the one for the TOUR. This is frustrating since they have gone silent after asking for the instructions. Not happy with their support . Does anyone know were i can get this service document .
