with the help of joao, thank god the board is working now. apparently there is a solder bridge underneath the board. manage to slice that thing out using my shivering hand.

Ok, you have an older version of the firmware installed. Therefore you have A1, A2, etc. The value on A3 doesn't move? What about A4? Is this one ok? João the other values are moving. only a3 is not moving. a several test on other place such as calibration, triggering the light, on the display stic...

here is the picture of my diagANA

Please go Radio Setup / DiagAna. Now look at the 4 values at the top. Do they change when you move the stick? If they all change please post the values For "RV" and "RH" when the sticks are at both ends and in the middle. The values we want are the group of four digits or letter...

hurm...i am still waiting for JK to response as i got the board from him. does anyone have experience returning a faulty board to him? would he bear all the cost involved? i am hoping this is just a minor firmware issue and just need reflashing but until further confirmation or direction from any of...

hello guys, i just got my ar9x board and still learning to configure this thing. i just realized that my right gimbal does not seem to register the input for up and down or channel 1 on the right gimbal. channel 2 is ok and i can move it to left and right. i realized this when trying to calibrate th...

hi guys. i am from malaysia and try to resource on this encoder thing. i am trying to have the cheapest option possible. andrew has this pcb. but if possible i would want the pcb together with the encoder. i could probably save more if it is shipped in one order. andrew has them too, but sadly the p...

JK? where is JK located?

shipping is the main issue for me as most of the parts come from region far away. the most i could afford right now is about 20 bucks plus the shipping. but actually i was hoping these 2 boards can be restored so that it would not go to waste. but to ship to you guys alone would cost me about 30 buc...

Hi kasturiGM, You may want to take the main board out to view the back side for other possibility of damage and may show what caused the short. This may help with your repairing of your 9x main board. thanks bob, but it's a little too late for me. the damaged already happened and getting worse. for...

500€?? that's a lot. but this is not my first time. i tend to have a destructive hands i think especially when it comes to electronics and soldering. i think that is it for now. never in my life i would use a soldering iron again.

anyway..thanks again. you guys help me out so much, just not my luck but i learn a lot. my best bet is moisture. from where i live, humidity can sometimes be your enemy. maybe i didn't realize the moisture i leave on the board.

btw i have replied your pm. if only there is someone nearby asia to help me solve this.

no, the battery was there the whole time in the battery compartment. i couldn't have reversed the 12 pins header because i would have notice it didn't fit. it kinda same but not really. because reversed polarity is very immediate and spontaneous. but this took about 2 seconds. and it starts from the...

not yet. i was just about to do what mike told me which is checking the voltage on the capacitor. when i turn on the radio, this happened. i was excited to finally know that maybe just the reset or crystal has to be replaced. i have a few references on the google and youtube videos. everyone showing...

hurm, i was jus about to do what you guys told me and this thing happened. my caps and probably the voltage regulator probably dead already. not sure how on earth a mistake from soldering few wires to program got to the upper side. just turn on the radio, a couple of second later, it burst into flam...

Ok. That is an UsbAsp, right? Do you knoe if it is working? Did you install the drivers? What OS are are you running on your computer? Windows? Is that your programmer on the photos? yes, it is an usbasp. i am not sure whether it is working or not since i never got to test it, all i can say that th...

anyway, if i don't reply after this, i might be sleeping. its 12 a.m here. ill catch u guys tomorrow. thanks again.

i am using this type of programmer. i thought its pretty standard.

i switch the radio on, it can't control anything but still be able to bind. but i guess thats only because the module is working. when connected to the trainer, nothing happens. and yes i have the rf module on it. oh so i got to solder the wires again..my least favourite part. it seems like every ti...

oh i mean top left. it has reading about 6.0k++ towards the end to the right its getting higher with the average of 9k. So, you mean they start reading 6K, but if you leave the probe in place the resistance go up to 9k? Or do you mean the left resistor(s) measure always 6k no matter how long the pr...

and yes the bottom part of the resistor has a consistent value close to 5k ohms.

oh i mean top left. it has reading about 6.0k++ towards the end to the right its getting higher with the average of 9k. i measured the resistors in yellow square and the both got about 0.8ohms. about the voltage between resistors. how should i measure them. which ground should i put. i mean voltage ...

its ok then. its a pleasure working with you, at least i learn something. it's more painful for you i think, working with a non technical guy like me ;). anyway i didn't see any changes with or without the lcd ribbon connected. the first one still measured the lowest among all the resistors and like...

if i move to the 2000 scale which i assume is 1k scale, the reading becomes 1100++ ohms. how weird..

i am not sure. it shows around 6.0-7.0++ on a 20k scale.
so is it 6.0 x 10k? take a look at the picture. is it correct?

but i got more consistent reading for the bottom part.

ops..sorry. for the top part, i got about 17 ohms in 20k scale. but it seems not consistent. i don't know whether the problem is with the probe on my multimeter itself or the resistor. i mean, it will get about 17 ohms for a second or two then fluctuate to around 6 ohms.

yes, they are in ohms. there is no reading for the capacitor. so i guess there is no short then, it has to be done without the power on right? as for the resistors for the top part, for the very first 3 resistor the reading is around 6.8-7.0 ohms and i am using the 20k scale but then the readings ke...

sorry i didn't see the reply on this page. on all points i got somewhere between 0.9-1.2v. i think my multimeter isn't properly calibrated. and i got about 4.92v between point number 1 and point number 2 ground. just the ground on point number 2 right and not on the processor. yes, i have checked th...
