RCA video output - no signal

  • I recently had a power cut whilst watching tv in my bedroom,
    I was watching via RCA from the dreambox on a channel on my motor which is on a diseqc switch port number one. Now after the power cut the RCA has sound but no picture and the diseqc port one is broken (all other ports are fine). I have replaced the diseqc switch just to be sure and all is fine apart from the RCA video doesn't work. I have also reflashed the box just incase, any help will be much appreciated.
