So, if you didn't solder the wires.... :o
Did you reverse the battery polarity? because the damage I see on your photo is really consistent with that. That orange capacitor has battery voltage on it and it normally burns if the battery is reversed..

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 small caps, i believe the non polarity cap and then spread to the orange cap.

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.

Bad luck! But don't give up!

Moisture really can be a cause. Once had to clean my pc. Carried it to the garage in winter time and blew it out with compressed air.
Fast back to the house (was cold!) and switched it on. Cost for repair ~ 500€. Hard way to learn :mrgreen:

For that price, you must have repaired it with a new one, right? ;) :mrgreen:

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.

There is the option, (if it come to it) to replace with the AR9X board: (http://ar9x.net/index.php?route=product ... duct_id=52) and (http://www.rcgroups.com/forums/showthread.php?t=2479552).
Video: (https://www.youtube.com/watch?v=VlmBIASrMwM).
This would be a large upgrade to use the erSky9x firmware too.

thanks bob, but it's a little too late for me. the damaged already happened and getting worse. for all i know, i would only risking getting the board worse and worse. from where i come from, smd parts have to be ordered online. i did that before for my first board and it was not worth it with all the shipping and my failed attempt. and now this, with my limited budget and the fact that i am from asia, it is just not worth it. i saw the part from hobby king, if i am from u.s, it would be worth it. it is on back order anyway.

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 bucks.

You can email JK at ar9x.net and ask how much the shipping would cost to your country. I believe he is not very far from you?
