Checking back after a while away...still no luck getting this thing to power up. Wondering if anyone has any ideas on where to get a new mother board or anything else I might check to pinpoint the problem? Does this seem like a bad MCU or could some other part suck up enough current to overheat the ...

I was poking around and found this: http://farm4.staticflickr.com/3932/33909609371_143d1e81b4_b.jpg I'm going to start unplugging I unplugged these one at a time to see if I can find any clues as to what might be pulling too much current and heating up the 5 volt regulator and to see if the unit mig...

Last night I plugged in a USBasp to see if I could possibly try re-flashing...no luck The radio powered up from USB power, but displays the same "LOADING" message/behavior. in eepe, I tried make a connection, but I got an error about "not seeing the avrdude" ...not sure if this i...

How does 5.9 M Ω sound?

(Not sure I'm measuring/reading correctly, but this is what I see)

Thanks ! I've only measured after removing the Orange DSM module (I took it out when I disassembled the shell), although the "stuck LOADING behavior" was the same before and after I removed it. I've neither removed nor installed the module with power on. I double checked the voltage of eac...

Thank you for the suggestions Here's what I see across the pad pairs: (in hindsight, I probably should have measured these from ground?) the 4 way pads read [up]=4.3v, [down]=4.3v. [right]=4.4v, [left]=4.4v the [menu]=338mv , [exit]=284mv on a cheap IR thermometer: the 5v regulator heats up to about...

Thanks for the replies...not giving up! I was just beginning to get the hang of the radio.

Sorry about the picture, I think I got it right now, but as João said, rubber rubbish indeed.

I'm game to try to fix it and really appreciate the help...still a bit ignorant, but learning.

I see there are replacement 9X boards available from Hobby King. Doesn't seem like this would be an option for me tho.

Anyone know if there are replacement 9XR boards to be found anywhere?

Would a "9XR Plus" board work in an 9XR?

OK, thank you, I really appreciate the help and am eager to learn more about how this all works. Here's a photo showing the board lifted away from the 4 way pad. It seems to me like the black discs in the square rubber boot are supposed to complete the "button" connection on the pcb? Pardo...

Thanks. I'm not entirely sure which model it was except that I believe it was the active model when I shut down last...I think model 4, but I'm not 100% certain. I see this corresponds to [UP] on the 4-way pad. I powered the unit on with board pulled away from the buttons so I know none are physical...

OK, thank you. No mods, the radio is bone stock except for the Orange Rx. I've tried powering up w/o the module, but same result...the LOADING model message. I don't sea any obvious problems anywhere--no burnt wires or loose parts,etc-- but now that the case is open I'll turn it on again and take a ...

It seems that the part getting hot (very hot, quickly upon power up) is a voltage regulator...KIA 78D05F I wonder if I might have damaged this with my charger--I used an old plug-in wall transformer rated at 12v, but when I measured it, it appears to be closer to 18v! I may have turned the unit on t...

Thanks so much for the reply...hardware problem makes sense. I read about the firmware feature that loads a model on startup depending on which key you hold down during power up. I've been using the keys heavily over the past few days trying to learn transmitter and make adjustments....maybe I wore/...

Hi...I'm new to flying please forgive my ignorance. I picked up a used 9xr recently. It's been working great, but this afternoon when I powered up (after using earlier today), instead of the splash screen, all I see is a message that says "LOADING" model XYZ. The screen freezes on this not...
