Re: 9xtrem burnt ..how? Don't know but wanna repair...please help
Battery plugged in backwards? I'll get you some info shortly on the components involved.
Re: 9xtrem burnt ..how? Don't know but wanna repair...please help
Thanks a lot, the thing is that everything is working except for the tx module bay....have check the othe components which usually burn and they seem to be fine ...the AO3407A is the component I think and control the output for the tx and it gives 3.5 v output so the tx module doesn't work....
Don't know if there is a cut in the trace board ...with the photo ...can u see a cut ? Or changing the mosfet will be enough? ?

Re: 9xtrem burnt ..how? Don't know but wanna repair...please help
What happened anyway? The module bay mostet being the only component burning because of a battery reversal is a bit strange
That looks more like a shorted module, or a miss connection of something to the module bay.
If the battery was reversed, I believe the first mosfet to go would be the radio's soft power one. And that is not damaged? Hnmmm..

Re: 9xtrem burnt ..how? Don't know but wanna repair...please help
Hey,thanks for the help....
Not fully sure is not damage, what I did to check its measured the voltage and it's 11.6 on the switch part, where you power the radio.
The thing is that I did not plug a reversal battery, one friend did in his radio and burnt everything but I have plug his TX module on my radio to check if it was working or not....after that without smoke or signals of anything my radio stop working ...I thought it was the battery 'cause one cell was damage and that will make my radio work again.....after that I thought time would solve the electronic Dixies of my radio ...and wait a month but after that I got piss off and open to see if it was something wrong and found that burnt.
The 9x original board seem ok without any visual signals of burn,as I said the part where you power on the radio with 3 legs give out 11.6 v which match the battery charge, the only part that I find not doing the job is the TX module bay.
But very appreciate if you let me know what do I have to check to make sure of not making wrong steps.

Re: 9xtrem burnt ..how? Don't know but wanna repair...please help
I thought so
What RF module?
Did you insert/remove the RF module while the radio was ON?
This would be very helpful information that could help others as well. That is why I am asking
Thanks

Re: 9xtrem burnt ..how? Don't know but wanna repair...please help
That could be what happens. ...yes ...I think I did plug in out the module with the radio on
I can say that 100% sure that I did 'cause it was month and a half ago but yes as far as I remember will give it a 90% .

Re: 9xtrem burnt ..how? Don't know but wanna repair...please help
hmm, flysky modules..
Maybe something shorted when you inserted/remove the modules with the radio ON. Never do that. It has caused all kinds of trouble to other people as well.
Did those modules work afterwards in another radio?

Re: 9xtrem burnt ..how? Don't know but wanna repair...please help
One of them , left in the photo, did not work , the other one don't know because after what happened dont have other modular radio to check.
After this, will make sure that the radio is off before changing module...I did know but was one of those mistakes that u have to pay someday

Re: 9xtrem burnt ..how? Don't know but wanna repair...please help
So any info ?,please, am I in the right direction?did I check everything or do I miss something??
If I replace that component it should work,doesnt it?

Well, let's hope you didn't do any more damage by inserting / removing the module with the radio ON.

Re: 9xtrem burnt ..how? Don't know but wanna repair...please help
Now when I was gonna check the voltage I have switch on the radio whiout all the wires from 9xtrem to 9x connected
What a messy mind this one that I have ,
So adding new problem, plug everything in place and is now turning on, it blink 3 times and show a 9xtreme and r00.3 on the screen.

Re: 9xtrem burnt ..how? Don't know but wanna repair...please help
Is the 9xtreme screwed on top of the 9x mainboard?
Perhaps the pogo pins are not making good contact to the little pads on the 9x board

Re: 9xtrem burnt ..how? Don't know but wanna repair...please help
Thanks for the answer.
The thing is that what I know is from a post here so I know nothing for sure.
The component is clear now.
-Should I check others in the 9xtreme?
-Could someone give me more link where to buy the component?have been searching on god Google but nothing near and the cost from digi key for shipping is 20€....found this:
- AO3407A X7HV AO3407 A7TA SOT-23 P-channel MOSFET 30 V 4.3A
http://s.aliexpress.com/RNjQRFJv
-https://www.amazon.com/20PCS-AO3407A-MO ... UTF8&psc=1
Worthy to buy, are them the same?
The only thing that doesn't work is the tx output as far as I have check following the post from burnt/reversed bateries, and that makes the radio unusable.Is that the mosfet that control the tx output?
Sorry if my English + grey material between my ears are a mess.

Re: 9xtrem burnt ..how? Don't know but wanna repair...please help
Yes they look like they are the same part.
In my opinion, You need to get that working in order to find out if there is any other damage, unless you own an oscilloscope.
Do you have a trainer cable ( 3.5mm jack plug to 3.5mm jack plug)? With that (instead of the oscilloscope ) you could test if the radio is outputting a PPM signal to the module. It already did happen that removing/inserting the module with the radio ON, damaged the processor pin that outputs that signal. Some people were lucky though..
But another little test, when you turn the radio off, does it wait a second or two before it turns off, displaying "shutting down", or does it turn off immediately as soon as you turn the power switch off?
