00:00Hello Friends, Welcome to Khaimpur Repair Youtube Channel
00:04This is Home Theater IC
00:07Let me show you the number of this IC
00:11This number is not clear
00:14Let me show you another IC
00:17This IC number is TDA2050
00:21It is written UTC2050
00:23But this IC is 2050
00:25Today I am going to tell you the pin details of this IC
00:29If you have a 2050 home theater
00:32Then you must watch this video
00:35I will show you a board of a 2050 home theater
00:41First you see this board
00:43This board is of TDA2050
00:46In this board you can see 4 ICs
00:50If you know the pin details of this board
00:57Then you can check the board
01:01And find out the problem
01:05Today I am going to make a video on this IC
01:09I am going to give you the pin details
01:11Let me make a diagram of this IC
01:20This is a diagram of a 2050 home theater
01:24This is a diagram of a 2050 home theater
01:28This is a diagram of a 2050 home theater
01:32This is a diagram of a 2050 home theater
01:36This is a diagram of a 2050 home theater
01:40This is a diagram of a 2050 home theater
01:44This is a diagram of a 2050 home theater
01:48This is a diagram of a 2050 home theater
01:52This is a diagram of a 2050 home theater
01:56This is a diagram of a 2050 home theater
02:00I have made this IC in this way
02:02I have written the number of legs of this IC
02:051,2,3,4,5
02:06This IC has 5 legs
02:09You can see how to count this
02:12Because the legs are up and down
02:15You have to count 1 after 1
02:191,2,3,4,5
02:23You have to count like this
02:25I am going to tell you the function of these legs
02:30I am going to change the color of the first leg
02:36So that you can understand the connection
02:40I am going to change the color of the first leg
02:44This leg is for inverting input
02:52You can give audio on this leg
02:56You can give audio from anything
03:00You can give audio from AUX
03:02Or you can give from mobile
03:04If you are using mobile or DTH
03:06You can give from DTH
03:08You can give from mobile or AUX
03:10You can give from anything
03:12If you want to give audio
03:14You have to give audio on the first pin of the IC
03:18This second pin is for non-inverting input
03:24Non-inverting input
03:31This second pin will be connected to the ground
03:36There will be a resistor and a capacitor
03:39You don't have to pay attention to this pin
03:41This pin is already connected to the board
03:43You don't have to pay attention to this pin
03:46If there is no audio
03:48You have to check on the first pin
03:50By giving audio separately
03:52If there is no audio
03:54If you give audio on this pin
03:56There will be humming or sound
03:59You will know if your IC is working or not
04:03You can check like this
04:06This is the first pin
04:08This is the second pin of non-inverting input
04:10If you want to know what is non-inverting input
04:13I will make a separate video on this
04:15Because a big video can be made on this
04:18I will not tell you in this video
04:21The third pin is of minus 16 volts
04:30This is from minus 12
04:35This is 16-18 volts
04:39These will be negative volts
04:43These will be different from ground
04:49This is from minus 12 to 18 volts
04:55I will show you the fourth pin
05:04This pin number 4 will be the output pin of the speaker.
05:11The connection I have made here is wrong.
05:18The connection I have drawn here is wrong.
05:21Actually, this leg is not this leg.
05:24This leg is of number 4.
05:26I have made it wrong on number 5.
05:29So, this leg is of number 4.
05:32On this leg, what will be found on number 4?
05:34Speaker output.
05:36This means that the wire of the speaker will go from this pin to the speaker.
05:44It will be direct.
05:45There may be a capacitor here.
05:47But, it will go to the speaker.
05:49The wire that goes to the speaker will go through one of the ICs.
05:51The second wire of the speaker will go through the second IC.
05:54There are two ICs on the buffer of the board of number 4.
06:00If you have a board of 4 ICs, then this IC will go to the speaker.
06:07There are two speakers on one IC of the board of number 4.
06:11And there will be one 6-inch buffer on two ICs of the board of number 4.
06:18So, this is how the board of 2050 works.
06:21I showed you the board at the beginning of the video.
06:24There were four ICs on it.
06:25Two ICs for the buffer and two ICs for the speaker.
06:28The connection that I have shown you is of pin number 4.
06:33This is not the connection of pin number 5.
06:36This is the pin of the speaker output of pin number 4.
06:45The pin number 5 is of plus volt.
06:48From plus 12 to 18 volts.
06:56You can get 12 or 14 volts on this pin.
07:00The more volts you get on this pin, the more minus volts you should get on this pin.
07:06It should not be that there are more volts on this pin and less on this pin.
07:09Both the volts should be the same.
07:11Only then your IC will work properly.
07:13I have given you the full details of all the pins of the 2050 IC.
07:19If I missed anything in the video, let me know in the comments.
07:23I will definitely tell you about it.
07:25If you want to know anything else about this IC, you can also comment.
07:29How did you like this video?
07:30Let me know in the comments.
07:31Like and share the video.
07:32See you in the next video.
07:33Till then, thanks for watching.
