00:00Assalam-o-Alaikum, this is the kit that we have to repair.
00:06Let's see what is the problem with this kit.
00:10Let's open it.
00:12We get this service from Leopard.
00:16Let's open it.
00:20They have packed it very well.
00:23Yes Sir.
00:24Perfect.
00:25Now it has come in a wooden box.
00:33This is a very hard type of material.
00:55Let's open it.
01:11Perfect.
01:20This is the kit.
01:22Let's check what is the problem with it.
01:27First, let's clean it.
01:33We have cleaned it.
01:35Now, let's give voltage.
01:38By giving voltage, we will know what is the problem with it and what is not.
01:44Now, let's give voltage.
01:46We will give voltage seriously because we will not put a duct in it.
01:49First of all, we do it upside down.
01:52By giving voltage in this way, we will know whether there is power in it or not.
01:57The red light is on.
01:59The capacitor is charging.
02:01Now, this light is not illuminated.
02:05This is the light.
02:06This is the small one.
02:07This light is illuminated when a microprocessor gets voltage.
02:11Now, let's see what is the problem with it.
02:14After taking it out and turning it off, I do it like this.
02:18Look down.
02:19Nothing has happened that it is short.
02:22Actually, the error in this is according to the fact that the microprocessor is not getting voltage.
02:30It will give an error of E7.
02:32So, it has an error of E7.
02:34Now, let's see how to clear the error of E7.
02:37First of all, we will see this.
02:40Look at this.
02:42I will give voltage to it again.
02:45First of all, we have to see this.
02:47A regulator 705 is installed here.
02:50It has 5 voltages and 12 voltages on one side.
02:52And 5 voltages.
02:53Look at this.
02:54I will make you check on the meter by putting it on 20.
02:57It should have 5 voltages and we should get 12 voltages.
03:01Look at this.
03:02We got 12 voltages like this.
03:05So, this is installed.
03:07There is no metal body on it.
03:09There is another one.
03:10When we check on this, look at this.
03:12We are getting 12, 5 and 12 voltages for this 15 voltage.
03:20Now, what is the problem in this that it is not turning on?
03:24Now, let's see what is the problem in this that it is not turning on.
03:28Let's see the voltage of its IPM.
03:30We are getting 15 voltages on it.
03:32As I told you in the first video, whenever you want to see the voltage on it,
03:36it always has this ground.
03:38This one is fine.
03:39Look at this.
03:401, 2, 3, 4.
03:43We are getting 5 voltages on number 4.
03:46Similarly, look at number 8.
03:49We are getting 15 voltages on 5, 6, 7, 8.
03:54It means that there is voltage in it.
03:56But there is a problem in the microprocessor.
03:58We are not getting the voltage up to there.
04:01Now, I am removing the microprocessor.
04:05Because there is a high voltage in it.
04:07Now, when we come to the microprocessor,
04:09look at this side.
04:11It has 4 sides.
04:13Here, it has 5 voltages.
04:162.25 voltages.
04:17We can say in other words.
04:18They come here.
04:20I will show you on the screen.
04:24Show them on the screen.
04:26Also, you have to monitor the voltage.
04:30Hold it like this.
04:31So that you can see both the things.
04:33I will show them here.
04:35Look at this.
04:36When I will put it here,
04:38I will show you like this.
04:40First of all, its ground.
04:42You can see it clearly on the screen.
04:452.25 voltages come to the ground here.
04:51And we should get 2.25 voltages on this pin.
04:58We are getting it, right?
04:59Okay.
05:00We are getting 2.25 voltages here.
05:03It means that the microprocessor is getting the voltage.
05:07But now, I will show the microprocessor here.
05:11You have seen the voltage here.
05:13We are getting the voltage on it.
05:15But what is here?
05:17It is not turning on.
05:18Nor it is getting hot.
05:20There is no problem here.
05:21It is completely cool.
05:22Now, the problem is that
05:24the error of E7 will come here.
05:26And the error of E7 will come because
05:28our microprocessor is damaged.
05:31Now, this kit will be changed completely.
05:34This PCB will be changed.
05:35It will not work.
05:36Its microprocessor is damaged.
05:39We are getting some voltage here.
05:42And the microprocessor is not turning on.
05:44Now, there is a lot of noise in it.
05:46I can check it even if there is a drop voltage here.
05:49It happens because of drop voltage.
05:50Sometimes, there is a drop voltage.
05:52Even if the microprocessor is turned on,
05:54there is a drop voltage.
05:55Otherwise, the voltage is complete everywhere.
05:57All its voltages are complete.
05:58High and low.
05:59If you hope that
06:01you have understood enough
06:03how to check.
06:05If you like my video,
06:06then like it and share it.
06:08And along with liking the video,
06:10do subscribe to our channel.
06:13Goodbye.
