I have several radios, including 2 of the Spectrum DX6.
I was in Maui flying last week and when I turned my radio on it was intermittent. Luckily it was before take off. I use this Radio a lot, and have for about 1 year with no problem.
It would work and appeared normal, but if I jarred/bumped the radio it would "reboot." A horrible thing to happen when you are flying.
What it turned out to be is the little piece of foam glued to the battery cove that holds pressure on the batteries. The foam is on in the middle of the battery door, and is not touching the outside two batteries, (If it ever did?)
Without the foam piece holding in the outside two batteries can slip out enough to loose contact when you bump the radio.
If it has shrunk over time, that is a really bad thing. I will compare it to the other exact match I have.
Knowing this,,, could save a few planes. And it makes me wonder if the group I fly with has lost any planes to this problem.
I think an item to add to your preflight list might be to bump the radio a few times and see of it loses power.
Before I fly again with this Radio, I will add additional foam to the edges of the battery door.
You night want to check yours and see if the foam holds ALL your batteries in.
The only thing I can think of, is that it stunk over time with heat? Let me know if anyone has any ideas.

I just found this on another forum. My symptoms were not exactly the same, but it confirms my suspicions.
Another DX6 Signal Loss event and cause I had a couple of DX6 Transmitter glitches the other day which may be worth sharing:
When starting up an Electric Estik with an Apprentice Receiver, the Aileron Servo was totally dead (all other servos were active). After Cycling the power to the Plane a couple of times, the Ailerons resumed working. The plane flew fine but after landing, the plane was completely unresponsive ... the Receiver was inactive (LED not lit). After several unsuccessful Plane Power recycles, I then selected my T28 plane with its separate Apprentice Receiver and also found no response. The Transmitter display appeared functional. I removed the Battery Cover and found that the rightmost AA Battery had partially dislodged from its contact (It was touching the Spring Leaf but was not seated). Further inspection showed that the Foam Rubber spacer glued to the back of the Battery Cover did not extend far enough on the right side and therefore, only this rightmost battery was not locked in place. I added an additional adhesive-backed foam spacer over the right battery position and found no further issues (passed range check, flew 6 flights on both planes, etc.).
I could be jumping to conclusions, but it appears that an intermittent battery connection could partially disable the RF output of the transmitter while the transmitter continues to present the normal display.
I recommend that users of the new DX6 Transmitters check to see if the Battery Cover Foam Spacer adequately overlaps all 4 AA cells. Newer stock of DX6 has this changed.

Where did you send the Spektrum DX6 to for repairs? I have a DX6 which now comes on for maybe 4 seconds then states transmitter low battery. I tried a total of 8 brand new batteries, all with same results! Thank for helping.
