I sent it to a service shop it turns out its something to do with resolution i took it home and pluged the cameras the same problem occurred

Have you tried a different monitor and/or different connection if avaialble?
For example connect it via VGA instead of HDMI.

More information needed. When you say there's nothing on the monitor do you mean nothing at all or gridlines and menus visible but no camera images? Do you get anything at all on the monitor when you first power up the recorder? Even if the resolution was set incorrectly on the recorder, you would still see the Hikvision logo at boot up, as it is displayed at a lower resolution to the monitor output setting. As @Phil says, if you're getting no image at all out of the HDMI output, try the VGA connector.
