Kelly See my posts regarding my DX9 battery discharge problem - page22 - Mike Ridley pinpointed the faulty FET on the top PCB - check to see, in a dark room if any LED's are glowing dim when Tx is switched off...joe

Morning Fella's Percy - He's better than good he's brilliant and magnaminous with it. At the time I emailed him he had another DX9 in for repair with the same same problem and discovered the faulty F.E.T = Q2 on Pcb DX9MBA RevF a very tiny SMD. So he sent me two replacements yesterday ( Gabriel's gona give him the key ) how good is that?? - I replaced the FET in my DX9 but because mine was an intermittent fault there was no apparent fix - but bench testing the removed FET I could not get it to operate like I did with the ones Mike sent me - so I must assume problem fixed thanks to Mr Mike Ridley Esq & Bar with Gabriel's Key...joe   Edited By Pete B - Moderator on 24/09/2017 09:33:01

Hi Fella's Just had an email reply concerning my DX9 battery discharging fault, from Mike Ridley - says he has another Dx9 with the same fault - going to let me know when he's found the fault - says he's very busy clearing Spektrum faults since HH UK jumped ship, namely this aircraft carrier Island of ours - seems a very OK fella...joe

Percy/ Steve I've heard that also ( ex SKYLEADER I think ), actually spoken to him a couple month ago, am going to Poole Dorset end next month may drop my DX9 off with him...joe

The DX6 & DX9 if I remember correctly their Li-on battery charger and protection cct pcb is built ito the battery pack whereas the DX9 Li-on battery charger and protection cct is part of one of the Tx's pcb's and the wall socket adapter only supplies 12VDC to the Tx - To overcome my discharge problem ( nothing to do with my bodily functions ) I installed a switch in one of the battery leads to stop this intermittent discharge. Although over the last week I have left this switch closed and the battery voltage has not dropped at all. So it would be very difficult to find the fault unless you know of it in advance - and Spektrum are very reluctant / will not tell me where the fault is - damn $$$$...joe Edited By stubtoe on 19/09/2017 14:05:06

Hello Regarding Al's Hobbies and Spektrum service it is true that he does provide a Spektrum repair service - I have spoken to him at Ridley Hall & Weston Park - he has an ex Spektrum engineer ( Garry )  in his employ 2 days a week. I think this maybe an unofficial arrangement at the moment but who knows, the future seems brighter !!?? but have purchased a Taranis and do still have my trusty FUT FF9 Q.. I have a DX9 with a fault ( who has'nt ) the battery discharges while the Tx is switched OFF - no it is not a senior moment, although they do occur more often now, please has anyone had the same problem. I've questioned RCG's and the best answer was - it is an FET problem !!?? - idea's anyone...joe Edited By stubtoe on 19/09/2017 09:19:29

Hi Steve Thanks for your reply - I've contacted ''Spektrum Community'' asking the same question - yet to hear from them - but you do confirm my fears - what a ''too do'' - if I was not so committed to Spektrum, got too many Rx's and 2 Tx's I would go for FrSky Taranis - damn and blast -  Brexit and their new Leader ''King Boso'' - Oh! btw have you heard of the fault I have with the DX9...joe Edited By Pete B - Moderator on 11/06/2017 17:04:59

I have the DX9 pre Jan 2015 so it is DMS2 compatible ( I want to keep this compatibility) cos I may have to send it in for repair The fault is the 2000mAh Lithium Ion battery discharges when Tx is switched OFF - yes I have double checked this cos I do have Senior moments. One evening in dimm light I noticed the front RF/Charging led's were dimmly lit - Ahhh Soooo ! - It does not happen every time I switch OFF cos now I'm aware of the fault I just switch it On then Off again a few times till it kinda goes away! Q - has anyone had a similar fault, if so is there a user fix, and if I do have to send it back to Spektrum workshops where are these workshops UK or Europe (Germany) - Germany because of Brexit!!?? - I think I read it on RCG that Spektrum have pulled out of UK, please confirm someone...joe
