00:00As-salamu alaykum.
00:02Hi, this is Geeta.
00:04It has come from one or two places.
00:06In this,
00:08E7 is written.
00:10And in this, there is a problem
00:12that
00:14in this, there is a problem of E7.
00:16Let's check why E7 is coming in this.
00:18Let's check why E7 is coming in this.
00:20This is the wire of its reactor.
00:22Let me attach it here first.
00:26After that,
00:28let me attach this
00:30wire here.
00:32Main. Let's give 220 in series.
00:34Whatever the condition is,
00:36the lamp will tell us
00:38what is the problem in this.
00:40We will go according to that.
00:42We have to fix it on the lamp.
00:44See, it is working fully.
00:46Something is short in this.
00:48And neither will the capacitor be charged.
00:50Now, we have to see
00:52what is short in this.
00:54Give me the meter.
00:58First of all,
01:00let's keep the meter here
01:02and see what is short in this.
01:04First of all,
01:06let's check the bridge.
01:08It is coated on this.
01:10It will be checked from here.
01:12It will not be checked from there.
01:14See,
01:16it is working on everything.
01:18See, they have removed everything.
01:20See, soldering is also not done properly.
01:22See, soldering is also not done properly.
01:24Let's see what the problem is.
01:26Okay.
01:28This is not short.
01:30Okay.
01:32Now, let's check it
01:34by putting it on diode mode.
01:36See,
01:38now the reading of this
01:40should be clear here.
01:42See,
01:44it is coming.
01:46See,
01:48and now,
01:50it is fine.
01:52Now, in this,
01:54after this,
01:56this is short diode
01:58and IGBT. Let's check this.
02:00Let's put this on diode mode.
02:02To check this, see here,
02:06this is also not short
02:08and this is also not short.
02:10Now, let's put this on diode mode.
02:12Let's take the reading of this.
02:14So,
02:16See,
02:18this is short diode.
02:20I have put this negative on this.
02:22I have put this on this.
02:24Let's check both of them.
02:26This is like this and this is like this.
02:28Both of these readings should be same.
02:30This is fine.
02:32The symbol inside this
02:34is black mark.
02:36See,
02:38the symbol of this is
02:40like this.
02:42The symbol of this is like this.
02:44This is like this.
02:46This is like this.
02:48And this is like this.
02:50This is like this.
02:52And this is like this.
02:54This is like this.
02:56Like this.
02:58This is like this.
03:00In the remaining,
03:02Now, let's see,
03:04my video is ready but
03:06let me tell you,
03:08how to check this.
03:10See,
03:12if we put this here,
03:14I have put this.
03:16I have given the reading.
03:18If I put this here,
03:20the negative will come here.
03:22The reading is same here
03:24and here also.
03:26This is the structure of this.
03:28And this is
03:30IGBT. You already know this.
03:32There is no problem with this.
03:34As we used to check earlier,
03:36I have started checking this.
03:38See,
03:40this is our
03:42IGBT.
03:44This is P channel.
03:46Now,
03:48it's turn.
03:50First, we will check
03:52IPM on continuity.
03:54This is shard.
04:00This is shard.
04:02This is shard
04:04from inside.
04:06Because of this,
04:08the light is full.
04:10Now, the way to check this is
04:12we have to see one more thing.
04:14See,
04:16this is also shard.
04:18Now,
04:20I will cut this.
04:22After cutting, I will check
04:24what is the problem in other board.
04:28See, I will cut this.
04:30I will cut this accordingly
04:32so that it will be attached again.
04:34So that there is no problem.
04:36See,
04:38you also see.
04:40I will put this
04:42from one side.
04:44Positive pin.
04:46See, I have opened this.
04:48Now, it can be easily attached again.
04:50Now, I will put this
04:52on series.
04:58See,
05:00the capacitors are charged.
05:02But, see,
05:04the lights
05:06are on.
05:08Capacitor is also charged.
05:10The lights are also on.
05:12This means
05:14that the
05:16IPM was shard.
05:18Now, I will check all other things.
05:20Then, we will
05:22get the right guess.
05:24We will know that there is no problem.
05:26See, it is discharged.
05:28Now, I will check the circle
05:30that the IPM and
05:32the microprocessor
05:34is fine or there is no fault.
05:36Now, we will check that.
05:38To check that,
05:40I have told you the whole method.
05:42Earlier also.
05:44But, now when
05:46IPM is E7,
05:48E7 has come.
05:50Now, I have opened
05:52the IPM and shown you.
05:54See,
05:56from here, see, it is shard.
05:58Now, the problem is
06:00that by changing our IPM,
06:02this kit will be OK
06:04and the error of E7 will
06:06be cleared.
06:08If you like my video,
06:10then like and share it.
06:12If any brother wants to take training,
06:14he can come and take training.
06:16If anyone wants to learn work, then he must learn.
06:18Because, this is the work of the future.
06:20This is a small work.
06:22This is not a big problem.
06:24You can also take training like this.
06:26After checking,
06:28there are many things that
06:30are under training.
06:32We will change this.
06:34After changing,
06:36the board is clear.
06:38You work on it.
