00:00Assalam-o-Alaikum.

00:02I am making this video.

00:05The kit has come to us in P1 error.

00:08You must watch this video.

00:10I have never said that this is a very useful video.

00:13This is a useful video for them.

00:15I am making it because I often see in groups, etc.

00:19Or people say that this is the kit of Dollars.

00:23Or it is the air condition of Dollars.

00:25When there is any green color, send the error code list.

00:29Send the error code list.

00:31I am making a special video for them today.

00:33Which is related to each other in groups.

00:36Yes, whose error is this?

00:38The P1 error in this is the purpose of whether the voltage is up or down.

00:43This is the error of voltage protection.

00:46If you check the voltage that we are getting here,

00:50then there will be 220 volts.

00:52Or there will be 10-12 volts up and down.

00:54That is also considered correct.

00:56But in reality, what will be this fault?

00:59If you have written there that there is a voltage problem,

01:02then what will you do?

01:04Nothing.

01:05You can just check the voltage.

01:07Yes, the whole thing is fine.

01:08Yes, there is a problem in the kit.

01:09In reality, these things do not happen like this.

01:11This is any error.

01:13It does not happen in such a way that people see the error of the sensors.

01:20This is why I am telling them that these things happen at any time.

01:26But there is a lot of difference in your understanding.

01:29How will this error be solved?

01:32Or how do we trace it?

01:35I am making a special video for it today.

01:37You must watch this video.

01:39Okay.

01:40No matter if you don't like it.

01:41No problem.

01:42But you must watch the video.

01:43Because you will get a lot of things in it.

01:47We have cleared a lot of such kits in this.

01:50But there is an error of P1 in this.

01:52Generally, mechanics make the kit dead in this error.

01:55That the microprocessor of this kit is bad.

01:58So much that it does not happen.

02:00Although there are more faults in this.

02:02Today I have made a diagram for you in this.

02:05I will explain according to this diagram.

02:08This is a pre-DC link in this.

02:10I will also tell you the diagram of this.

02:13And this is P1 only.

02:15In this, there is a DC link.

02:16This is also an error in P1.

02:18We have cleared both of these.

02:19The purpose is that you should know this.

02:22What is this diagram?

02:23Where does it start from?

02:25How far is it?

02:26What are the things that come in this?

02:28What components are being used in this?

02:30What are they doing?

02:32First of all, see this.

02:33This bridge is installed here.

02:35Which is in every kit.

02:39There is an AC in its center.

02:41And see this.

02:43See this first.

02:44After this, I will explain to you.

02:46See this.

02:47Here this DC out comes from the cut side.

02:50After this, this reactor is installed.

02:52This is also installed in the common kit.

02:54And this reactor is installed in it.

02:56Immediately after the reactor, this short circuit diverges.

02:59Which is below it.

03:00I will show you that too.

03:02After this, two capacitors are installed.

03:04On which 325 volts will come.

03:07These are plus and minus.

03:09Two electrolytic capacitors are installed.

03:12After this, let's go here.

03:14These capacitors are installed.

03:16This capacitor is installed.

03:17AC voltage controller.

03:18This capacitor is installed in front of it.

03:20After this, here is a resistance installed.

03:25This one.

03:26This polar resistance is installed.

03:28After this, a capacitor is installed.

03:30And after this, see this.

03:31This diverge package is installed.

03:33This came in front of it.

03:34Macro process up to 89 pin.

03:38Now after this.

03:40We see that after this, what is this?

03:44The real P1 error comes because of this.

03:47What we are seeing today.

03:48On which I am getting you to work.

03:50This is the same type.

03:51This is a DC circuit.

03:54Link circuit.

03:55See this.

03:56This happens in this.

03:57Here.

03:58From here.

03:59From here, this one wire from here.

04:01Which is before the reactor.

04:03DC starts here.

04:05Before the reactor with it.

04:07This resistance will come.

04:08This polar resistance.

04:09After this, it will come in this package and come here.

04:12The second one.

04:13It has to tell.

04:14Will the voltage work here or more?

04:17The second one.

04:18The capacitor's voltage is less or more.

04:20This circuit has to tell.

04:21Okay.

04:22These are two circuits.

04:23In this.

04:24Now in this.

04:25We clear the error of P1.

04:27I have opened it.

04:28See this.

04:29We check this.

04:30See this.

04:31First of all.

04:32This one.

04:33This is the circuit.

04:34We trace it.

04:35See this.

04:36In this.

04:37The resistance is in this.

04:38These one powers.

04:39It can go there.

04:40If we see it.

04:41This will tell here.

04:42Here also it is showing 1000 watts.

04:43Here you see.

04:44Oh!

04:45Why is it 1000 watts?

04:46Because here a voltage is low.

04:47That is why we have cut the capacitor.

04:48The distance from this node goes out, back here.

04:49Then this is understood.

04:50Then the other one and like this.

04:52And there is a resistance here also.

04:57See in the front below.

05:01On this on this.

05:02Is burned reddish.

05:03There will be more.

05:04because in this, like this,

05:12I should have told this, why am I not telling this?

05:22Yes, see this, this is correct.

05:24It will tell from one side, and when it gets damaged,

05:27then it will start giving wheeling from both sides.

05:30You have to see this too.

05:32Because it is connected through the diver.

05:35And in this, from here,

05:37after this resistance,

05:39from here,

05:41the circuit of this,

05:43I will show it to you on the screen.

05:46Please switch off the light and show it on the screen.

05:49See here, it comes here.

05:53Here.

05:54After this, it will go straight from here,

05:57and it will come here on this diver.

06:00It will come here.

06:01This is the diver.

06:02From this, one resistance will come from here,

06:05and from here, this CV,

06:07it will come straight here,

06:10above the microprocessor,

06:12above this line,

06:14it will come here.

06:15Okay, one is done.

06:17One circuit.

06:18Now let's see,

06:19where does the other circuit come from,

06:21how far does it come,

06:22let's trace that too.

06:23After this, we will check the voltage and all.

06:25See here, this reactor is installed.

06:28After the reactor,

06:29this is the short-cut diver.

06:30This is the short-cut diver.

06:31After the diver,

06:32after the diver,

06:33this,

06:34see here,

06:35this resistance is coming,

06:36this one.

06:37Now from here,

06:38after this pull-up,

06:39from here,

06:40this package is installed.

06:41Here, 5 volts,

06:42this 3.2 volts should come here,

06:45and in the same way,

06:46this is,

06:47this too,

06:483.2 volts,

06:49here,

06:50here,

06:515.

06:52The voltage here,

06:53it happens,

06:54that here,

06:55for some reason,

06:56here,

06:57here,

06:58here,
