help me with Multicam machine please

Hello. My name is Mariano. I'm from Argentina. I have problems with my Multicam V Series plasma cutting machine. There is actually no technical support in Argentina. The installer of the machine is from Brazil and He can't help me. I started having problems with control... the display apparently changed the resolution. That way I lost the visualization of some cutting parameters. I tried to solve it but now the machine does not work. I need help and I don't know who to turn to. Thank you.
