00:00Assalam-o-Alaikum,
00:03As you can see on the display, there is an error of E7.
00:07Now we will repair it and see where it is from.
00:12This kit has been sent to us from Khanewal.
00:17This brother has sent it to us for repairing.
00:21There is an error of E7.
00:23Now we will solve the error of E7.
00:25Now we will solve the error of E7.
00:30Now we will turn it off.
00:32I have turned it off.
00:34After turning it off, the error of E7 is due to the SMPS supply.
00:43This supply is not being turned on.
00:46The current is not getting out of it.
00:49This is attached to it.
00:51First of all, let's check what the problem is.
00:55As you can see, there is a lot of movie on E7.
00:59If you are watching this, there will be 10-15 more movies.
01:05I am making this movie because of this problem.
01:08All the movies made so far have been made on one error.
01:12But it is not the opposite.
01:15There is only one error, but it is not the same.
01:18I will make a movie for you according to the different faults in each.
01:23So that you can trace all the faults of one error.
01:28Now let's see what other problems come in it.
01:33Because of which this error comes in E7.
01:37I have removed almost everything from it now.
01:40I also remove this compressor.
01:42See this.
01:44This AC wheel is attached to it.
01:47You know this.
01:48My video is complete.
01:50You can watch videos on YouTube.
01:53On my channel.
01:54See this.
01:55I have removed its part.
01:57Now let's see in this.
01:59I am trying to make a short video.
02:04So that whatever problem you have in it, you can clear it as soon as possible.
02:10Rest.
02:11Where does this thing come from?
02:13What is the reason for the fault?
02:15And how did this trace come in the brain?
02:18My brother, this is a gradual experience of a person.
02:21It turns out like this.
02:22It doesn't happen that I have started working today.
02:25Then I will know the next day.
02:26Some experience happens to a person with time.
02:33I take all the traces of this.
02:35Okay.
02:36Nothing is left of it.
02:38There is nothing in it.
02:43Okay.
02:44I had a touch like this.
02:46I checked everything.
02:47Now I put it in it.
02:49Now I check it.
02:51See this.
02:52This is attached to it.
02:53See this.
02:54Okay.
02:55Mosfet.
02:56Mosfet is also fine.
02:59The resistor is hot.
03:00It is very hot.
03:02Let's check it.
03:03Now I see in it.
03:04I am not getting anything short.
03:07I am not getting.
03:08Like this.
03:09Everything is fine.
03:10Now with this.
03:12See this.
03:13There is a lot of SMD here.
03:17Now I have started checking this SMD.
03:19Because this fault often comes in SMD.
03:21This is also a charge.
03:23We also discharge it.
03:25This is also a dangerous thing.
03:27There is a little current in it.
03:29May be.
03:38See this SMD.
03:40This is dead.
03:42This SMD is dead.
03:44And let's check the rest.
03:46There is nothing else in it.
03:47There is something in it.
03:49There is something in it.
03:51This is also fine.
03:53Only this is there.
03:55It is small.
03:56It is 15 ohms.
03:57This is also fine.
03:58Everything is fine.
03:59And this is dead.
04:00This is 10K.
04:01Let's check it.
04:02Let's change it.
04:03Give us 10K.
04:05SMD.
04:06Resistance.
04:08Let's change this SMD.
04:28See this.
04:29I have removed this SMD.
04:32See this SMD.
04:34Let me show you.
04:36Let me clear it.
04:38See this.
04:39This is enough.
04:40See this.
04:41See how much this is.
04:45Okay.
04:46You have seen the SMD.
04:48Now I will put this.
04:50And I will remove it first.
04:51Okay.
04:52Whenever we have to remove this.
04:54We hold it like this.
04:56Now I will show you.
04:57Remove it.
04:58I have turned on the iron.
05:01See this.
05:09I have to clean it.
05:11Because in this.
05:13There is a paste.
05:15It damages the board.
05:17Now we have done this.
05:19Change.
05:20And now we.
05:22Let it dry a little.
05:25Or with the help of a tissue.
05:27You have to dry it like this.
05:29You have to dry it.
05:31So that.
05:32There is no problem.
05:34There is no sparking here.
05:36Now in this.
05:38There are two or three things to see.
05:40First I remove this jack.
05:42Now this part is separate.
05:44And this is separate.
05:45Okay.
05:46Now the voltage should come here.
05:48On this side.
05:4915.
05:50And in the center.
05:51Ground.
05:52And on this side.
05:535 voltage.
05:54Which I.
05:55Which we will give it now.
05:56Separate supply.
05:57I am giving from here.
05:58We will supply to the gas.
05:59Here.
06:00When I put the supply from here.
06:02So.
06:03The part here.
06:04That is my off.
06:05Everything will be off.
06:06Only check what will happen.
06:07I only have this current.
06:08I have repaired it here.
06:10Whether my current came in it.
06:12Or not.
06:13Or the two lights of it.
06:14That will also burn.
06:15By giving current here.
06:16It should not be that.
06:17You give current on this.
06:18On this.
06:19On this side.
06:20Put it on the module.
06:21There is no need.
06:22To put anything.
06:23I am here.
06:24Direct.
06:25I will give it a current.
06:26Okay.
06:27I will give it in series current.
06:28Or give it directly.
06:29No problem.
06:30No tension.
06:31You do not have to give it.
06:32Clean it from below.
06:33There is nothing in it.
06:34And here.
06:35Now I will check.
06:36Its voltage.
06:37Look here.
06:38When I put it here.
06:39So.
06:40Its voltage.
06:41I put it.
06:42And its voltage.
06:43You have to see.
06:44Whether it comes or not.
06:45But in this.
06:46There is no need to see the voltage.
06:47We check its lights.
06:48It has two lights.
06:49Its from here.
06:50The camera will have to come from here.
06:51Yes.
06:52I will show you.
06:53It is running here.
06:54So.
06:55I will show you.
06:56It is running here.
06:57See.
06:58As soon as I started turning it on.
06:59See this.
07:00See this.
07:01Our light is on.
07:02And after that.
07:03See this.
07:04This light is also on.
07:05You must have seen it.
07:06The rest is the problem of voltage.
07:07As far as we check that too.
07:08We make you check.
07:09So that.
07:10It does not remain in your heart.
07:11That the voltage is not checked.
07:12Okay.
07:13See this.
07:14I have turned it on at 20 volts.
07:15The meter.
07:16See this.
07:17By putting it here.
07:18This center.
07:19I am here.
07:20On the ground.
07:21By putting it here.
07:22I am here.
07:23I am here.
