CONNECTION BREAK fix
00:00:00:00 00:00:08:27 Hello~~ Today I will repair the IMAX B6 charger.
00:00:11:00 00:00:19:27 If you try to charge the battery without the battery installed, a message is displayed with a warning sound.
00:00:20:26 00:00:29:23 For this reason, check the battery connection cable.
00:00:46:04 00:01:10:04 If the cable is normal but "CONNECTION BREAK" is still output, there is a problem inside the charger.
00:01:24:25 00:01:29:18 Unscrew the 8 screws on both sides.
00:02:00:14 00:02:04:17 Remove the 4 buttons of the operating switch.
00:02:47:16 00:02:55:27 Remove the 3 screws securing the PCB.
00:03:15:22 00:03:24:19 Check the bottom of the case, which acts as a heatsink.
00:03:31:16 00:03:40:13 This is because if the bottom and the MOSFET are in direct contact, they can receive damage from the outside.
00:03:42:04 00:03:51:01 I checked the Schottky Diode and MOSFET and they were fine.
00:03:54:07 00:04:03:06 No damage was visible on the surface of any part.
00:04:05:17 00:04:14:14 "CONNECTION BREAK" error code is most likely a problem with the battery output part..
00:04:18:15 00:04:26:20 I checked the datasheet and confirmed that the 12H3LL is a MOSFET. Let's check.
00:04:42:21 00:04:54:16 GATE and SOURCE are shorted to each other.
00:04:56:23 00:05:08:20 I'm going to replace the MOSFET.
00:05:18:02 00:05:26:29 Removing the resistor makes it easier to swap out the MOSFET.
00:06:34:22 00:06:42:15 I used a 4920N mosfet from an old lcd inverter.
00:06:43:21 00:06:52:18 Because I didn't have the 12H3LL, nor the replacement parts IRF7413 or AO4468.
00:06:58:09 00:07:08:19 However, the circuit needs to be modified to use the 4920N.
00:09:06:02 00:09:32:10 Connect jumper wires.
00:10:06:04 00:10:23:19 Restore the resistor that was removed.
00:10:30:13 00:10:39:09 The parts replacement is complete, and I will assemble in the reverse order of disassembly..
00:11:44:10 00:11:55:02 It's done, let's test it.
00:12:35:02 00:12:45:24 It's working fine past the point where the error was displayed.
00:12:52:04 00:12:59:13 Today's video will end here.

You r awesom...and qualify person...😇
I cant find these device in Brasil! Liked
You don;t need to remove the buttons. Flex the top of the case where it meets the base on the top and bottom edge and they pop apart.
hi, one of my resistors burned out (the resistor close to the output)... any idea what broke and did need any change?
Hi, informative for the video! can i ask for the resistor's value? mine is burnt hoping i can also replace it . Thanks!
Thank you for watching!
See video 4:51, 4 Band color resistor
good job bro 👍
Thank you for watching!
저도 전원 반대로 인가되 타는냄새나서 보니.동일부품이
잏부 깨졌네요.
회로 패턴은 안보이고.
구해서 교체 해봐야 겠네요.
감사합니다.
시청해 주셔서 감사하고, 성공하시길 기원합니다.
what is tht ic nunber
Hi... My Imax B6 AC charger, enter button is not working, i am pressing it for a second or pressing for long time let say 10-15 seconds but it is not working.
Can you please let me know what is the issue.
Thanks man
Thank you for watching!
Thank you. But my device notice “ volt error” when i charge balance Lipo 1ampe …(2s), confirm or cancel then warn “volt error”. And i charge two batteries connected in series i use power input 12v 120w , choose charging method pb battery, confirm and cancel, then notice volt error. Help me
제가 밧데리 + -연결을 잘못해서 딱 그 모스핏을 태워 먹었거든요?? 그 모스핏 모델명은 nce3**10인가 그러든데 교체할수 있는 정식 모델명 말씀해 주실수 있나요??
미안합니다. 질문을 이해 하지 못하겠습니다.시청해주셔서 감사합니다.
Hi interesting.
I have imax b6 mini, while checking with "battery meter" function, I heard a pop sound and burning smell. After that point, it is showing same error as yours. But on the PCB there is no burning or damage signs.
Any thoughts pls?
@@something_else_123 It was covered in thermal paste and removed all and checked. No visible signs though...
Если это еще актуально: проверь стабилитрон 5v, находится в самом верху возле дисплея, он один такой красный, стекляный или отследи по плюсу питании зарядки.
❤😂🎉😢😮😅😊. ไฟแอดพ์
How are you my friend what is the solution to this problem CONNECT ERROR CHECK MAIN PORT
What is the value of the register taken out?
I think it was less than 10 ohm, but I don't remember exactly what the resistance value was. And I didn't replace the resistor.
Thanks for watching!
Why after i start charging the amperes start going down till 0.1 A
11:46 Is the "Build.Power iMaxB6" firmware the stock or custom?
Thank you for watching!
@@something_else_123 Thank you for answering my question!
@@bleak0218 It is stock. (default)
@@something_else_123 Ok, thanks!
I could do with knowing the value of the grey resistor with black & green bands - can anyone help please? Many thanks.
Is 50 ohm
Thank you for watching!
Kak mosfet dibawah berapa dan tipenya apa?
good technique just replaced it.
MOSFET NCE3010🎉🎉
or u throw it in the bin and buy a genuine one 4 only 35$.......
This imax is fake
