I had this problem the input rf was good, the ac was good the dc was bad the rf out was bad. First thing i did was replace the le module same problem. Next I replaced the le housing, same problem. Then I checked the active before this le, It was good.
Then I checked the hardline ( it was 500 ) it was not shorted. I had good dc loop resistance. both input to le and output. Finally i was at wicks end so I used a temp rg-11 drop from the tap before
the bad le to the le and problem was solved. This was 5 years ago in okinawa japan and it was so weird that I rember it to this day. In theory the bad peice of 500 feeding the le should not have ac and surly should not have had good loop resistance , turns out that when I put the module back in the load was when the problem was noticed. This took place on Labor day and I was in some @ssh0l3's backyard and had to deal with the "are you done yet ?" question every 5 minutes.
