Recently picked up 2 Hydra 26 Non HD units that both seem to have the same issue. The ribbon cable that goes to the power button and status light has failed.
So I have basically required it… ordered new cable, put in a reset button, added a smd diode… but I still cannot get it to connect to the controller. Documentation is almost impossible to find. I am using the old wireless controller .. I believe it was version 2… not the one with rubber buttons. I have tried channels 1-10 and still get nothing. I am assuming that the module that powers this connection has failed over time.
where and what new cable did you order? the power ribbon cable (touch membrane)? all 5 of mine wont even turn on...
Sounds like you might have a wifi chip issue, which no replacement parts for. Typically the entire board needs to be replaced, which is also no longer available anymore.
