Title: Fried my FS-I6s radio by Reverse Polarity. (Help me Out) Post by: YashasR on September 06, 2017, 04:39:07 PM :help: :help: :help: Today when I was inserting the batteries in my remote, I noticed a orange glow and burning smell from the connector area. I instantly took out the battery and this happened for about 2 seconds. Then I agained tried with the correct polarity and it didnt switch on. :banghead: I have attached some pictures of the Transmitter and the circuits. Visually, I can only see the fried capacitor. I read many more forums on this issue based on similar transmitters from this manafacturer. In most of the cases there is problem in the voltage regulator and the capacitor.

Will the motherboard for Th-9x work in FS-i6s? Title: Re: Fried my FS-I6s radio by Reverse Polarity. (Help me Out) Post by: sanjayrai55 on September 06, 2017, 07:06:17 PM I'm not too sure. Maybe you could check with girishsarwal

Title: Re: Fried my FS-I6s radio by Reverse Polarity. (Help me Out) Post by: Balakrishna Reddy on September 06, 2017, 08:43:52 PM It looks like you have a burned capacitor on it according to the PCB picture from the link below.
http://fishpepper.de/wp-content/uploads/2016/09/fsi6s_pcb_layout.jpg If you can see there is an identical capacitor nearby. Now you can buy the similar capacitor in local market and should replace the damaged one. You can even buy the regulators so that in case if they are blown out too you can replace them as well. But as per your pictures they look fine. Title: Re: Fried my FS-I6s radio by Reverse Polarity. (Help me Out) Post by: YashasR on September 06, 2017, 10:35:07 PM Sanjay, I am having a FS-I6s radio. I just gave the link for Flysky 9X just for reference or idea. Thanks for you reply :)

(Help me Out) Post by: YashasR on September 06, 2017, 10:38:44 PM It looks like you have a burned capacitor on it according to the PCB picture from the link below. Thanks for that image but I am not able to read the figures on the capacitor in the which is burnt in mine because its not so clear. Could you post a zoomed pic of that so that I can read it, or could you give the link to the site of this image? That picture can be really helpful to me. http://fishpepper.de/wp-content/uploads/2016/09/fsi6s_pcb_layout.jpg If you can see there is an identical capacitor nearby.

Title: Re: Fried my FS-I6s radio by Reverse Polarity. (Help me Out) Post by: YashasR on September 07, 2017, 07:00:04 AM I will order the parts as soon as possible and will post a update if it works or not. If anyone has something more to share, please do. All the participation of the members was really appreciated. :)
Title: Re: Post by: kn8alpha on September 22, 2017, 12:46:35 AM Just desolder the capacitor and clean any traces of burning. Probe across the capacitor terminal at the pads to check if any short exists.. then power on and see if it works. If it doesn't, adding a new capacitor might not help in that case.
