My screen does not work after replacing superdrive

I have an iMac 21.5, EMC 2389 model. After replacing the Superdrive with a SSD I have damaged the monitor data cable (APPLE P / N 593-1280 VENDOR: ACON) and has come out a cable wire vertical sync LED card (APN: 593-1237 REV : A VENDOR: LW). The case is now unbootable iMac screen after being turned off, however if it boots the screen when I restart the iMac. Know if these symptoms may be normal for educated the monitor data cable?, Where I can buy these cables?

Thanks for your help and sorry for my English by google traslator.
