00:00Assalam-o-Alaikum
00:05We have a kit and the problem is that it has an error of F1
00:12The main reason is that
00:15I didn't want to talk about it but I am forced to do so
00:19Anyway, in this
00:22Often it happens that there is an error of F1 or there is an error of sensor
00:27You must have seen on YouTube
00:30They say that the wire was cut and the sensor was changed
00:36But they say such things
00:40But it happens that
00:43Such things do not happen
00:46Any fault comes and always
00:49Look, we have a kit
00:51We have their sensor
00:54Although this is the fault of the room sensor
00:57If you see its list or check on the net or check somewhere
01:01The fault of the room sensor will be
01:04If you watch the movie on YouTube, they will remove the sensor
01:08They will put it or say that it was cut
01:11The purpose of this is that such a problem does not happen
01:14The problem is that whenever a component is damaged or a problem occurs
01:19For many reasons, this microprocessor was damaged in a kit
01:22So its F1 error was coming
01:25The purpose is not this
01:26The purpose is that some fault comes
01:28Because of which the error comes
01:31No matter what the error is, no matter what the error is
01:34You should see it
01:35Why is it coming?
01:36Why is the error coming?
01:37What should be done in this?
01:40Sensor is our own sensor
01:42This is not of our customer
01:43We have kept it on our own
01:45We also apply this
01:48If there is a problem in it
01:50Error
01:52Because of the error sensor
01:53Almost in my service
01:5699% of the errors come because of this kit or component
02:01They do not come because the sensor is broken
02:03This problem does not happen
02:05We also applied this
02:07As soon as we turn it on
02:08As soon as we turn it on
02:09See this
02:10It is lying like this
02:12As soon as I turned it on
02:14See this
02:15As soon as I turn it on
02:17See this
02:18Now this is fine in it
02:20Sometimes F1 comes in it
02:22Sometimes some problem comes
02:25Now I close it again and run
02:32This F1 came
02:34The purpose is that
02:35Now the problem of the sensor is not
02:38There is something wrong in it
02:39Something
02:40There is a shortage in it
02:42Or any such
02:43Dice hold
02:44Or what is the problem
02:45That problem
02:46This problem comes because of it
02:48Sometimes it works
02:49It never works
02:50See now
02:51Turn it off
02:52It is still F1
02:53Turn it on
02:54It is still F1
02:55Now F1 in it
02:56If it is turned off
02:57If I take it out
02:58So see again
02:59I put it
03:00It is still F1
03:01The problem is that
03:02This F1 is constantly coming in it
03:04Sometimes it comes
03:05Sometimes not
03:06This customer also had the same problem
03:08That it works sometimes
03:09It never works like this
03:11But this does not happen in it
03:12That its sensor
03:13Sometimes it gets better
03:14Sometimes it gets bad
03:15This is not the problem
03:16Now let's see
03:17What is the problem
03:18Let's take it out
03:20First of all
03:21We remove the sensor
03:29We have removed the sensor
03:30Its jack
03:32Now let's see
03:33What is the problem in it
03:35When you see this
03:36You are in front
03:37I show you on the screen
03:38See this
03:39It is written
03:40Tuner sensor
03:41Room sensor
03:42Now the room sensor
03:43In this
03:44F1 is showing
03:45Let's see
03:46What is the problem in it
03:48I trace its circuit
03:49All complete
03:50With the meter
03:51See this
03:52I put it on the Metricom
03:53I put it on the Metricom
03:54On other mode
03:55See this
03:56It has
03:57This is one side
03:58See this side
03:59See this side
04:00See this side
04:01See this side
04:02See this side
04:03It is attached to its ground
04:04There is no problem in it
04:05See this side
04:06See this side
04:07There is no problem in it
04:08There is no problem in it
04:09There is a straight line
04:10But there are five voltages
04:12They are also coming
04:15If I can also make you check
04:16If I can also make you check
04:17See this
04:18See this
04:19This is right here
04:21This has five voltages
04:22In it
04:23Also coming
04:25If you want
04:26I will get you checked
04:27See this
04:28I will get you checked
04:31Some say
04:32It will check the five volts
04:33Okay
04:35Check five volts
04:36So, this is the 5 voltage checker, there is no such thing as 5 voltage, hmm, I don't know.
04:52Okay, so, 5 voltage is also being shown here.
04:56The purpose of this is not whether 5 voltage is coming or not, or if 5 voltage is not coming, then it is a separate issue.
05:04If 5 voltage is coming, then still sensor error is coming, so this is called sensor change.
05:09So, there is no solution for sensor change.
05:12There are many other faults in this, because of which these problems occur.
05:17See, we trace the circuit like this.
05:20See, this circuit, from here, you will hear the sound of the buzzer.
05:24See, this is its end point.
05:28And this is its, see, its pulse field is coming here.
05:32Passing through this SMD resistance, see, from here to here, now it is coming here.
05:38After this, see, two capacitors are connected from here.
05:41After this, see, if you see the circuit from here, then this way, see, I trace the circuit to you again.
05:48See, it came from here.
05:50Here, now I have applied buzzer mode so that I can trace the circuit to you, okay.
05:54It comes from here to here, okay.
05:58After this, see from here, it comes straight from here to here.
06:04It came here.
06:05Now, after this, it came straight to this microprocessor.
06:11Now, we have to see, first check the circuit in this.
06:14After that, if there is no problem, if we do not get any problem, then we will check it with DSO.
06:20This is DSO.
06:22We will check with DSO whether the pulse is coming or not.
06:25We will see that.
06:26First, let us see this.
06:27Let us check.
06:28If there is a problem, then it is okay.
06:29Otherwise, we will check with DSO.
06:33Okay.
06:34Now, I will trace the circuit from here.
06:36Now, I will place the circuit here and keep the meter on here.
06:41See, now you can see the circuit on both sides.
06:45Now, let us trace the circuit.
06:46From where is the problem in this?
06:48See, now I will place it from here.
06:51So, it came straight from here to here, okay.
06:55Now, the resistance is also checked.
06:58Now, the resistance is okay.
07:00Now, I will place it from here to here.
07:03Okay.
07:04From here.
07:05See this.
07:06Okay.
07:07One circuit came here.
07:08Okay.
07:09Its assembly came here.
07:11See this.
07:12Here, it means that this is dead.
07:18This has to be checked.
07:20This capacitor is weak.
07:22Now, I will change it.
07:24I will change this capacitor and see.
07:26I will see what is the problem in it.
07:37See this.
07:38Now, I have changed its capacitor from here.
07:41Now, this has come.
07:43This one.
07:44And see this.
07:45Both things will not be covered together.
07:48But I will show you.
07:50See this once.
07:51Here.
07:52See this.
07:53Our reading show is done.
07:55Okay.
07:56It means, show it from here also.
07:57Pass it from here.
08:01Keep meter aside.
08:03One minute.
08:04See this.
08:05Now, both things.
08:07Now, the circuit has been completed here.
08:10Now, let's see by running it.
08:12Whether it works or not.
08:14Or what is the problem.
08:15I hope it will work.
08:18I have installed the sensor.
08:19Now, let's see the display.
08:21Let's see what it does or not.
08:23Okay.
08:24Let's see the display.
08:26Now, I will switch it on.
08:29See this.
08:30I have switched it on.
08:31See this.
08:32The signal of OFF has come.
08:34It means, it is OFF.
08:36See this.
08:37I have switched it on like this.
08:38See this.
08:39The temperature has come.
08:40Now, I will switch it off once again.
08:44I have switched it on again.
08:49See this.
08:51See this.
08:53When we switch it on,
08:54the wire is loose.
08:59See this.
09:00Okay.
09:01See this.
09:02The temperature of this.
09:03This is complete.
09:04Our kit has been repaired.
09:06Now, in this,
09:07you have to see this.
09:08You have seen that
09:09we have changed only one component of this.
09:13Our kit has been repaired.
09:14Okay.
09:15It has been repaired.
09:16But, it has become weak.
09:17It is not a big deal
09:18that anything gets damaged.
09:19It happens.
09:20But, the problem is that
09:21now, I have repaired it.
09:24I have shown you that
09:25it has been repaired.
09:26The kit is fine.
09:27But, the purpose is that
09:28I have not done this
09:29that it was broken in this.
09:31It was like this.
09:32It was like this.
09:33The purpose is that
09:34it is a matter of concern
09:36to any person
09:37or any person
09:38who works
09:39or sees you.
09:40It is a matter of concern to him.
09:41It should not be done like this.
09:43The problem arose
09:44because the component got damaged.
09:46So much so that
09:47if we had changed
09:48a hundred sensors
09:49out of this,
09:50the kit would not have been repaired.
09:52It would not have been fixed.
09:53If you like the video,
09:55then like it.
09:56Share it.
09:57And,
09:58if you like it,
10:00then subscribe to the channel
10:02so that
10:03you can get
10:04better videos in the future.
10:07Along with this,
10:08if anyone is interested
10:09in learning a job,
10:10then he can come to us
10:11and learn a job.
10:12Okay.
10:13Goodbye.
