Hi all I have experienced this recently as I have 3 receivers and SPARE modules I very quickly isolated it to the IF module ,which I have PUT to one side to fix on a rainy day of which in Australia  we don't get too many of   these days,but I noticed that it has the tubular black bypass caps with coloured rings ,I have found these caps to be leaky in the past, the fault was as you described ,At first I thought it was lightning but after disconnecting the Antenna I realised it was inthe RX
