Title: fs-ct6b tx accidentally I reversed the battery after that it is not powering Post by: rahulbaruri on August 23, 2020, 07:52:00 PM fs-ct6b tx accidentally I reversed the battery after that it is not powering but using usb its red light is dim glowing and my laptop device manger is showing port is ok connected..
Need help ??? Title: Re: fs-ct6b tx accidentally I reversed the battery after that it is not powering Post by: Balakrishna Reddy on August 23, 2020, 08:51:52 PM Generally the input section has a voltage regulator and capacitor. When you have connected battery in reverse polarity the capacitor and regulator would blow up.
However the output section of the regulator is functioning normally which is why you can observe tx working fine when connected to PC. You can open up your tx and replace the burnt components and most probably it will work.

Title: Re: fs-ct6b tx accidentally I reversed the battery after that it is not powering Post by: sahilkit on August 24, 2020, 11:20:45 AM the ic in the black marking is U2 78L05 voltage regulator. Check to see if voltage is coming and its 5volts! Download the data sheet for pin marking from Google.
Title: Re: fs-ct6b tx accidentally I reversed the battery after that it is not powering Post by: sahilkit on August 24, 2020, 11:29:14 AM This must be the main voltage regulator. Post a picture of the other side to confirm once.
