HELP ! My T/X went dead for a while .
« on: September 13, 2019, 10:33:44 pm »
Hi Everyone,
I have a Spektrum DX6 G2 T/X and while hooked up to one of the planes at home, the screen just went blank and there was no kind of response being transmitted. I know that the voltage on the screen before this happened was reading 7.1 V and it was supposed to give a warning of low voltage at 6.4
Not wanting to disconnect the battery on the plane , i tried moving the controls and switches on the T/X but still no response, the screen just remained blank. I then decided to connect the charging cord to the T/X and everything came back on the screen.
Is there something wrong with the T/X, or the voltage reading ?  I would hate to have this happen while i have a plane up in the air and no control from the T/X.  Please advise.......I plan to fly tomorrow  ??? ??? ???

Hi William:

Try to fully charge your TX battery. If it is LiPo, then 6.4V warning is only 3.2V per cell. If you saw 7.1V then that’s 3.55V per cell which is getting low. Fully charged is 4.2V per cell (8.4V for the pack).

If the TX runs when plugged into the charger then I think your issue is with a bad battery or one that is nearly discharged. A bad battery may have high internal resistance which lowers it’s output voltage under load.

So charge the TX battery and let us know if your TX works (or not).

Richard,

I had a look at it TX this morning.  It had a Spectrum Li-ion pack in the transmitter.  I removed the battery and removed the plug just in case there was corrosion.  There was none.  The black wire was exposed in several places so I covered it with electrical tape, re-plugged the battery and closed the back.  We had 6 flights with it no problem.

Hi Richard,      After Frank had a look at the battery pack and did a little repairing , we had no problems with the TX , and everything seems to be okay. Thank you Frank, for your help and keen observation with the black wire.
As you suggested Richard, I will be checking to see the condition of the battery pack , whether the pack is getting weak and going bad.
Thank you for replying.             William.
