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.
