00:00Assalam-o-Alaikum.

00:02This kit came to us for repairing from Chakwal.

00:05Let's open it and see what problem it has.

00:09Let's open it.

00:25Let's open the kit.

00:28They have tried to repair it.

00:31Let's see why it hasn't been repaired.

00:35Let's check the problem.

00:37Try to repair any kit that you send to us.

00:42It will be easier and better.

00:46But you can see all the repaired kit.

00:51Don't do this.

00:53It will be a problem for us.

00:56Now the problem is E7.

00:58E7 means that E7 comes at night and E7 doesn't come at day.

01:05This is the problem.

01:07Let's check the reason.

01:12Let's open the kit.

01:15We have removed the kit.

01:18I don't check much.

01:23There is no need to check.

01:25There is a fault.

01:27Whenever there is a problem, I change the capacitor.

01:33Whenever there is a problem.

01:35E7 comes at night and E7 doesn't come at day.

01:38There is a fault of sensors.

01:40I have made a video on this.

01:42You can watch it.

01:44There is a fault of sensors.

01:46These capacitors are weak.

01:48If you look at the micro faraday, you will see that it is true.

01:52These capacitors are weak.

01:54These capacitors are weak.

01:56As time goes by, the electrolytic capacitors.

02:01If I remove these capacitors and check, they will tell the truth.

02:05But when there is a load on these capacitors, it weakens its capacity.

02:11That's why there is a problem.

02:14I will tell you what they have done.

02:18Look at this.

02:20Look at the solder.

02:22They have done a bad soldering.

02:24Let's fix this.

02:26We will not let it go.

02:29Because this looks bad.

02:32They have done this for the purpose of repair.

02:35They are worried that there is a communication error in E7.

02:41But, communication is made for many reasons.

02:43Look at this.

02:46Look at this.

02:47They have put so much carbon on it for no reason.

02:51What is the use of it?

02:52Look at this.

02:53Now, let us put everything here.

02:55Look at how much solder they have put.

02:57I did not understand the use of it.

02:58What did they do by thinking?

03:01Now, let us re-solder it again.

03:02Look at this.

03:03It is done now.

03:04Okay.

03:05Look at this.

03:06Okay.

03:07Look at this.

03:09Look at this.

03:10I have soldered it again.

03:13I have done it again.

03:15Now, look at how much solder I have removed from this.

03:20Look at this.

03:21Look at how much it was.

03:23I did not understand its use.

03:24What did they think of?

03:26Or, for what reason did they try to put so much solder on it?

03:30Or, what is its use?

03:32I do not know this.

03:33So, I am going to clean it now, I am going to clean it now, I am going to clean it now,

04:00I am going to clean it now, I am going to clean it now, I am going to clean it now,

04:01I am going to clean it now, I am going to clean it now, I am going to clean it now,

04:02I am going to clean it now, I am going to clean it now

04:29Now you can see that it is completely clean.

04:33Check it like the original one.

04:35See, it is 100% clean.

04:41Because, now it is completely clean.

04:45The purpose of applying so much solder is over.

04:49If you apply too much solder, it forms the opposite carbon.

04:53It doesn't finish.

04:54See, it is completely spotless.

04:56Along with this, they have re-applied this.

05:00I don't know what they have done to the kit.

05:02I don't understand what they have done.

05:05They have re-applied this and re-soldered it.

05:07Their purpose was to apply something.

05:10It is possible that the kit will be switched on.

05:13They have worked with such a system.

05:15Now, let's fix this too.

05:17It has come to us.

05:19Let's fix it properly.

05:21So that the work should be clean.

05:25Look at this.

05:29Look at this.

05:31You can see it.

05:33Look at this.

05:35Look at the soldering.

05:37The soldering is excellent.

05:39Look at this.

05:41If the work is good, then also it looks good.

05:44If the work is...

05:48This solder is applied too much.

05:51It is not beneficial.

05:53In fact, it is detrimental.

05:55Let's remove it and apply a new solder.

05:58Look at this.

06:02Look at this.

06:04Now, we will apply a new solder.

06:06And...

06:09Look at this solder.

06:11This one is common.

06:13But this is special.

06:15It is not black.

06:17It does not contain carbon.

06:19We use it for roughing.

06:21And this one...

06:23If we have to apply a new solder...

06:25Or if we have to repair a kit...

06:27Then we use this one.

06:29This one.

06:31It never gets a complaint.

06:33That your solder is dry.

06:37And it has one advantage.

06:39That the print is never damaged.

06:44Those who apply a low quality solder...

06:47They do not apply a good quality solder.

06:49With that...

06:51Whenever they repair a kit...

06:53Or repair anything...

06:55Of any kind...

06:57It happens that...

06:59When someone has to remove it again...

07:01Or has to do such a problem...

07:03What happens?

07:05Because the solder is of low quality.

07:07Because of which...

07:09That kit, that thing...

07:11It spoils the print from below.

07:13Look, now it is like this...

07:15Whenever you remove it...

07:17If you remove it...

07:19Or anyone removes it...

07:21Then there is no problem...

07:23That the kit has been damaged.

07:25100%

07:27This was E7's error.

07:29E7's error used to come at night.

07:31So they did all this...

07:33That it may be removed.

07:35But because of this...

07:37It never gets removed.

07:39Because if we have to remove the fault...

07:41Then the error is removed.

07:43It will not be removed like this.

07:45Now...

07:47We have also changed its capacitor.

07:49Capacitor has been changed.

07:51Now our kit is OK.

07:53Its module...

07:55Let's check it too.

07:57Let's turn on the module too.

07:59Now...

08:01We have changed its capacitor.

08:03I just have to check it.

08:05I don't have to give AC voltage from there.

08:07I am giving AC from here.

08:09We have also installed this.

08:11Everything is OK.

08:13We have also changed its capacitor.

08:15Soldering is also damaged here.

08:17Everything is OK.

08:19Now let's run it.

08:21Our kit is OK.

08:23It has started.

08:25Its light is on.

08:27It has also given the sound of the relay.

08:29Sound is OK.

08:31The sound of the relay has also come.

08:33Our kit is OK.

08:35Now this fault...

08:37That E7 comes at night.

08:39That fault has been cleared.
