hi..just got voom today (long island ny) and the ota module seems to be dead...i already had a hi-def antenna so i just used that with the voom box..voom box just continues to say ota signal is at zero strength (if i disconnect cable from voom box & use my own hi-def tuner it works fine so i know antenna is good)...any tricks to try?..installer noted on paperwork that ota was not working..im thinking maybe module needs replacing..maybe there are jumpers or switches on it...?
