00:00Aslam o Alaikum, this is a higher gate sent by E7 Airline from Karachi.
00:10See, they sent this from Karachi.
00:13It came like this. Now we will open it. There was another cover on it.
00:18But we removed that. Now we will open it. Let's see what problem they have sent.
00:30It's very hard to open it.
00:46They have packed a lot. How did they do it?
01:09These are the sensors and this is the new model of PCB Air.
01:15They have told us the error of E7.
01:18Let's see if there is anything burnt in it.
01:25They have soldered this.
01:31They have soldered this too.
01:36They have soldered this too.
01:40The gate is very good. It's a new condition gate.
01:44Now let's check the error of E7.
01:51Let's check it cold first.
01:53Later we will give voltage to it.
01:55Let's check the IGBT and short gear diode.
02:21Let's check the IPM.
02:27Let's check the diodes.
02:35Let's check this diode.
02:39Let's check the IC.
02:47Let's check the number of the power IC.
02:54Let's check the number of the power IC.
03:03Let's check the number of the power IC.
03:32Let's check the number of the power IC.
04:00Now let's open the heatsink.
04:04Give me the screwdriver.
04:16Now we have removed the screw.
04:19Now let's open the heatsink.
04:22This is the heatsink.
04:23It's very clean.
04:26Let's put it aside.
04:28Now let's check the IPM.
04:32You have to check the low and high side of the IPM carefully.
04:36I have read a lot of movies on this.
04:39You can also check it.
04:40You can also check it.
04:41You can also check it.
04:42So that you know how it is checked.
04:54This is fine.
04:57Now let's check here.
05:00Now let's check here.
05:05Now let's check here.
05:30Now let's check here.
05:44Now let's check here.
05:45Now let's check here.
06:05Now let's check here.
06:35Now the high side was safe
06:37Now the high side was safe
06:42and it was showing that the macro processor is flawed.
06:55that the macro processor is flawed.
06:58that the macro processor is flawed.
07:00I will check it to see if it is working properly.
07:05So that we can be more assured.
07:09Yes, it is working now.
07:12The microprocessor is not working properly.
07:28I have checked it from both sides.
07:31The microprocessor is dead.
07:34There is no point in working on it.
07:37It is not necessary that every kit has to be repaired.
07:41If there is any fault, it cannot be repaired.
07:45The main purpose is that you should know how to check things.
07:52What am I looking at?
07:54From where am I checking?
07:55How am I checking?
07:56And how will I know that there is a fault in this kit?
08:01If you like my video, then like it and subscribe to the channel.
08:06If you want to do any kind of training, you can do that too.
08:10Goodbye.
