00:00Assalamualaikum, this kit came from Peshawar to be repaired.
00:08Let's see what is the error in this. Let's open and see.
00:13Okay, this is an Orient kit. They have written that there is an error of F1 and E5.
00:35Okay, now let's see this. I will open and check this.
00:40We have opened this kit.
00:47Okay, now there is a double error of E5 and E1.
00:54And they have said that we have changed the IGBT of this kit.
01:02Actually, I have made many videos on this topic.
01:05If the IGBT is not working, then always check it with the gate.
01:12When it happens with the short gate, then it should not be installed again.
01:16Because it causes a disturbance in the driving system.
01:22Because of which the main IC of this kit burns.
01:26Never do this.
01:28Now there is an error of E5.
01:38Now there is an error of E5.
01:42Now there is an error of E5.
01:47First there was an error of F1, then E5.
01:49Then there was E5, they have changed its IGBT.
01:54Then this error started coming.
02:00The condition of the kit is very clean.
02:02It is very fresh.
02:05E5, F1. Now there is an error of E5.
02:12Let's clear this.
02:14Again there will be an error of F1.
02:16First of all, we will check it with a meter.
02:19We don't put a bolt in it.
02:21So that we can check it with a meter.
02:24Let's see what's in it.
02:26Because it has been repaired.
02:28It is a key, so it could not be repaired.
02:30Now I will check it.
02:32I will show it to you.
02:35If you like the video, then subscribe to the channel.
02:38Like the video.
02:46Now let's check it completely.
02:57Because this error comes.
02:59Let's clear E5.
03:02Because E5 is most dangerous.
03:17Now I will check its IC.
03:23Now I will check this one also.
03:26This is an op-amp circuit IC.
03:29Its number is LM258.
03:35And this one also.
03:37Now it has a reference resistance.
03:40Let's check it first.
03:42Then we will turn it on.
03:44Now it's ready.
03:48Now let's check it.
03:50I have shown you in the camera.
03:52So that you can know.
03:54What is going to be checked in it.
04:02See, this is its reference resistance.
04:05Now I will change it.
04:07See its value.
04:08It should be the same.
04:09But see this.
04:11Now this is its value.
04:12And now its value is this much.
04:15See this.
04:18Let's turn on the meter.
04:22We have to check its value.
04:24I will do it once or twice.
04:26So that it is clear.
04:27After this, let's check this one.
04:32This one.
04:39Okay.
04:40Okay.
04:42This is also okay.
04:43Now I will check its main microprocessor.
04:46That there is no problem in it.
04:48Let's put one ground here.
04:50And the other one here.
04:54See this.
04:55Its pin number is like this.
04:57Just pay attention to it.
04:59Then you will understand.
05:00See this.
05:01It is one number from here.
05:03Here it is not its.
05:04It is not everyone's.
05:05It is its.
05:06Don't think that everyone's will be like this.
05:08There is a difference in its leg.
05:10There is a difference in its count.
05:12But this system will be the same.
05:14See this.
05:15I will start from here.
05:16This dot is with it.
05:17From here to 13.
05:18Here 26, 49 and 50.
05:21Okay.
05:23This is its 52 here.
05:24See this.
05:25Up to here.
05:26I am checking its reading.
05:32See this.
05:33We checked this from its reading.
05:35And after this, see this.
05:37See this.
05:3840, 41, 42, 43.
05:40Number.
05:42I will check its reading of 43.
05:47Okay.
05:49It ends here.
05:51And after this, we will check this.
05:54Okay.
05:56After this, this is its check point.
06:00Let's call it.
06:04After this,
06:051, 2, 3, 4, 5, 6.
06:07This has come.
06:09After this, see this.
06:10It will not come 0, 0.
06:12See this.
06:13This has come.
06:14This is now in it.
06:15Its IC is burnt.
06:17Its IC is damaged.
06:19In this, the first error of E5 is F1.
06:22After F1, when they put IGBT,
06:25then what happened in this is
06:27that its gate
06:29was shut.
06:30After the gate was shut,
06:31the high voltage in it
06:32came with it.
06:34When it came here,
06:35then because of this,
06:37its microprocessor was damaged.
06:39When the microprocessor is damaged,
06:41then because of this,
06:43its gate was shut.
06:45Its gate has been crossed.
06:46Sorry, its IGBT.
06:48As soon as the gate was crossed,
06:50its microprocessor was damaged.
06:52Whenever there was such E5,
06:54E5 came at that time instead of F1,
06:57when they put its IGBT again.
06:59If they had not put its IGBT like this,
07:03F1 would have been cleared.
07:05When the time came to put IGBT,
07:08we had to check its gate.
07:09We had to check its gate driver.
07:11We had to check its complete system
07:13and put it.
07:14Then it could have been OK.
07:16Now they have spoiled it.
07:17There is no solution for this.
07:19If any brother has taken training,
07:20then he can take it.
07:22With this,
07:23Khuda Hafiz.
