9XR won't fully power up

Postby jeffbetts » 27 Feb 2013, 05:50

I recently received my 9XR and LiPo designed for it. I attached my DragonLink Tx using the PPM, Vcc, and GND pins where modules connect and everything worked perfectly. Yesterday I picked up the radio to setup DL receiver, but the LCD doesn't turn on, and it appears the system is no longer booting at PowerUp. (The Green light on the DragonLink was on when powered up indicating it was receiving the PPM data stream.) this is now a red light. The blue "ready" light does come on, and I I've tested most of the red wires inside the radio with a multimeter and get 12 or 5 volts in most places.

Can someone tell me where I should begin to troubleshoot this? I've done all I can think to do, and don't have a working radio to compare readings against.

Thanks!

No joke, I just had this exact problem last night.
I was editing a mix, the screen flickered a different screen very quickly (I think 'warning' was one of the words on the screen), then turned off.
READY light is the only thing that comes on now, no backlight. Have checked power to all the boards, which all seems to be fine.

The only difference to jeffbetts is that Im using a FrSky DJT module, so I don't think it has anything to do with the module/PPM.

I'm also looking for troubleshooting info, as now I don't have a radio to use =(

Thanks

I thought I should get a voltage reading at J2, as this is where the LCD appears to get its power, but I only get 0.01v reading here (signal?). The jumper wires connect to either side of the ribbon cable which I'm guessing is for the LCD display (which isn't powering up either)

J2 is for backlight power, which is controlled by the atmel chip.

I think the problem is a little more serious than the lcd getting power, since (at least with mine) the Tx doesn't beep or anything when switched on with a switch out of place. This would suggest that the software isn't running.

I agree, the problem is more than just the LCD. Mine isn't booting, or making a sound when powering on either. But, this was one of the places I was expecting to find power and didn't. Where does the Atmel chip get it's power? I'd like to see if there's a short that's keeping it from getting power, or mark this off the list and move on to other possible causes. Is there a wiring diagram available anywhere?

There's probably not a wiring diagram. I would imagine it gets its power from u5 or u3 at a guess.

You should have battery voltage and 5v on the pins on the regulator on the main board.

If not is the fuse on the rear of the daughter board an option?

I do have 12v in and 5v out at u5; and 5v at +mark of u3. So this seems to be as it should be.

I checked the fuse with continuity meter and it's solid.

I am currently going through getting an RMA with Hobbyking.

Has anyone had any experience with sending them items that have been opened? I have opened mine and installed tactile switches too (which I can remove), but I won't bother sending it back if they're very strict.

Is the 9XR motherboard entirely different from the 9X? There seems to be much more info available for the 9X since it's been around a while. I'm hoping someone will know how this problem can be further diagnosed. Where else should I check for voltage/continuity?

Got mine working!

It turns out to be a software problem. I think somehow my eeprom was corrupted to a point where the radio reset or something while trying to load it. I'm going to see if this is a known bug with er9x.

As for getting yours working: I had er9x flashed on my radio (not the '9xr' software), and was able to get it working again when I flashed my old eeprom file form the original software. Er9x says that this eeprom is invalid, and formats the eeprom again. I lost all my models etc, but at least my radio works.

If you've got any eeprom files, try flashing one that would be invalid for whatever software you're using. If you haven't flashed it at all, you'll need one of these: http://www.hobbyking.com/hobbyking/store/__21321__USBasp_AVR_Programming_Device_for_ATMEL_proccessors.html

Let me know if you need an eeprom file.

That's great news. My 9XR is pure stock, but I do have a USB-AVR dongle. I only have one model setup, so no big loss.

Please send me the file I need to flash and I'll give it a try. Thanks.

Sorry for the delay man, ive been sorting out a new house and haven't had internet.

Right, flash er9x_eeprom.bin that I attached. Just google companion9x, download it, and click the "write eeprom memory from file" button.

That might work. If not, I would suggest trying to flash er9x software itself, since I think it's a little better anyways.

Good luck

My 9x ralso doesn't power up. How can I flash it if it doesn't power up? I downloaded Companion9x, but it can't establish connection with my transmitter... "avrdude did not finish correctly target doesn´t answer" How can I have my transmitter back?

Are you using a HK USBASP programmer? If so is the green led on when you plug it in to your PC?
Have you loaded the USB drivers onto your PC?
Does your Tx operate (turn on) when the pc/programmer is plugged in to it?

Yes I'm using HK Usbasp.
Yes green led is on.
Yes USB drivers are loaded in my PC (I had flashed Er9x)
No, my Tx doesn´t turn on when the pc/programmer is plugged

Are you interested in taking the tx apart and using a meter to track where the usb power is reaching?
I would post this issue on the 9x forum if I were you, there is plenty of helpful advice there.

See my post above that has a photo. I explain where I'm getting power, and where I don't have power. Sounds like its the same as almarco. I haven't had a chance to flash mine, but will try that soon. I'm not optimistic it will fix the problem. This seems to be more than a firmware problem. Does Turnigy have reps that monitor this forum, or it is totally user based? Who wants a radio that may go dead at any moment? I almost ordered another and just chalked it up to buying a cheap radio, but if this problem is more widespread, I'm thinking I want to put my trust in something else. If I can troubleshoot and fix, that would be my preference.

The guys that know this stuff used to come here but decided not to any longer some weeks ago. As I have said, if you both post your problem on the 9x forum, where they all hang out, you will get all the help you want.

Thanks mpjf01. I've avoided posting there, since this forum is 9XR specific, and this seems to be a 9XR problem. I'll reconsider, thanks.

The 9x forum is basically run by the guys who wrote and support the 9X firmware (ER9X) and also other firmwares such as OPEN9X. But there's plenty of discussion about hardware issues with the 9x and (less so) 9XR radios.

With a little help from a friend I got some voltages:

with power off and program cable usb connected:
Atmel VCC+: 5.07 v
5v Reg: 5.09 v
J25: 4.16 v
J2: 0.0 v
With battery and power on:
Atmel VCC+: 5.02 v
5v Reg: 5.02 v

Where are you measuring the Atmel VCC and 5v Reg? Can you post a photo so I can be sure I'm measuring from same locations? Thanks!
