67 and still learning i've just learnt more in 10 minutes than i have in 5 Years Mate you are the bees knees a gift of teaching is what you have thank you for making electronics a lot more interesting for someone who was ready to just chuck stuff in the bin because he couldn't get answers God bless you ....
Can not find anyone who can fix tv,s where I live so I’m very interested in learning electrical to fix them , I’m a beginner but gotta start somewhere, this video was definitely helpful , thanks a bunch . 👍
Thanks for explaining in simple terms how to check transistors and diodes. It appears that using the diode mode rather than the ohm setting on your meter is a much easier way to tell if you've got a bad one. Regards, Tom
Thank you so much brother!! I learn a few things with your video by using the multimeter specially for your detailedly explanation again thank you so much
Its good to learn about basic electronics,but the truth is they do not teach of how to determine in bipolar transistor it is PNP or it is NPN and how to know by tester its pin is base,colecctor,emitter by reading not by position of a transistor or MOSFET transistor
Good I liked it. Just one observation. Transistors cannot block voltage, even if a transistor is open you will still have a voltage across it. Transistors will block a current flow or it will let it pass. That is what it will do. But in general you are a good teacher....
This is by far the most helpful video I have found on this subject. I have an LED grow light and one of the drivers blew a resistor and I replaced it and it just blew the new one as well. I figured there had to be another issue somewhere down the line, so I have been trying to find a video to tell me how I can test each part of the driver. I haven't gotten to it yet but once I do this video is going to be a great help. Thanks so much, keep making great informative videos and I'll keep watching!
This is super helpful. I am trying to fix a Halloween inflatable that has the "short circuit" light effect. These are "simple" circuit boards, however I am not a technician. I have tested everything on the 2 small circuit boards. There seems to be a transistor that is not functioning. Sadly I have tried finding the transistor number and have had no luck what so ever. Thanks so much for the great video it really helped a non technician like me.
Sub'd a while ago, but didn't thumbs up/comment (my Son just explained the importance of doing those things) so I'm back to correct that while refreshing my memory on the parts & procedure needed to fix our 42" Phillips TV! Your info/vids helped me identify the problem & clearly showed me how to repair it using a repair kit (or the easier but more costly replacement power supply board) however I wasn't confident enough with my soldering skills to attempt the repair at the time I found your vids (might have tried despite my fear if our TV only needed 1 or 2 things soldered but the amount of obviously bad "bits"on ours & amounts recommended to be changed or contained in the repair kit far exceeded my DIY bravery LOL) & I haven't been able to swing the cost of a new PS Board so the TV has just been collecting dust.... I quit watching TV a couple years ago so it hasn't bothered me but my Son is a gamer & really misses the big screen...his only wish for Xmas this year is having the TV repaired so I'm hoping to gain enough confidence to do the repair by watching more of your helpful vids...wish me luck!!!
Thanks for the great video! I have a little knowledge on electronics. I decided to dedicate some time to learn more about it because I have a few amplified speakers which don't turn on and my mission is to be able to fix them myself using only youtube videos like this one and others where they do repairs and explain how amplifiers work... Hopefully it doesn't take too much time. I saw a comment on a website where a guy mentioned "check the MOSFETs they may be the reason of the speakers not turning on.."
Its was very very very perfect and useful and interesting tutorial video. Please upload more like with video. Please test and check components of mainbord on laptop please, like resistors and capasitor and ceramic capasitor and mosfets on laptop, you teaching sooo easy and perfect
This is a hobby of mine. But I forget it doubt self and this was like best refresher tecer thanks man. Couldn’t remember few ins and outs. Now I just say thanks 🙏
Very nicke was of s Bowling how a Diode and a Transistor Workshop. It is a Pitt that the Viehs werde sometimes very Short ,ohne or two seconds, that is WHO i Hand to Look at your Videos twiсe and now I have learnt something I can even show to a friend of mine how to read it.thanks very much. Abele suisse
Dude thank you so much. I am trying to learn to fix & create electronic devices. You explain things very clearly. I appreciate the metaphors and visual representations. Keep up the great work!
Hey Bro,I don't feel as stupid as before,good job,learned a few thing,but it will take a bit of practice to get it down.But this video helped me out with a good start,Thank you my man,,,,Mark
im a macgiver and a avid dumpster diver i find electronic devices some are broke ive fixed some some i caniableized for parts your videos are a big help for some one like me that is self taught in electronic repair ive even built my own suround sound module out of spare parts when i was 12 im 42 now it finally fried a year ago because of a bad storm knocked out the power and took out my pc power strip and extra surge protector found out the telephone pole got shattered by a lightning bolt tooth pick city
I know this is an old video, but the information is still good. It would be helpful to know how and where to order replacement voltage regulators and transistors and diodes.
Thanks! I found a bad voltage regulator in my headphone distribution amplifier thanks to your video. Ordered the replacement part on ebay. It was a MC7805C I found the MC7805CT as the replacement. Data specs look the same, but I can't figure out what the T at the end means. Probably something simple that should have been apparent.
Thanks for the video, it is very helpful to me. I am into arcade games and pinballs as a hobby so I need to learn the basics of electronics. Right now I am trying to fix a skee ball board that has something shorted out and this video has been helpful how to test some of the components. Thanks.
Cool videos TampaTec...keep em coming!!! I live in TPA as well, I am an Electrical Engineer by Schooling, but have worked as an I.T. guy all my life. Keep making videos !!!
***** How do i diferentiate a transistor from a voltage regulator they look similar?great tutorial!Right now i am working on a reel to reel with a problem on the control area.it wont play when i actuate the play switch (switch is good)CheersRob
You have a great site,I'm having trouble repairing a TVL power board,TV is LCD,no power at all when I turn on the TV I can hear a very faint clicking noise coming from the power board,there are no bulging caps,I had a similar problem with a stereo amp,I changed an orange cap and it then worked fine,could it be one of the 104k capacitors.thankyou,you have the best RUclips posts.
In your video, you have a ohmmeter illustration showing that you can check semiconductors. I believe that since the voltage across the probes is so low, the semiconductor will not be biased into conduction. You could do this with an old analog meter but modern DMM can't hence the diode selection on the meter.
thank you very much, May God bless you I just learned a lot, this is the best video please make more videos about relays ,caps and transformers and other component Thank You again.
I learned a lot from this video . Illustrations help out a lot thank U ! How about capacitor video like those box cap how to test and stuff the weird one's ? Thanks again
i like those videos you presented. Sir, kindly give us more or send us the video in trouble shooting in all parts of television and if you have a module on a CCTV sir kindly share it to us... thanks

Bro the way u teach is simple and understandable. 1st time someone speak locally regularly.not like books
ime in the industry for some 20 years and this guy knows his stuff you can trust his guidance
Tampatec, your tutorials and others like yours are what makes RUclips great !
Thanks, James.

nice thank you
BY THE WAY YOU ARE HELPING SO MANY STUDENTS TO LEARN SO MANY THINGS FROM YOUR VIDEOS ,THANK YOU .
Thanks for this! Aside from sussing out device failure, it's good stuff for checking out cheap Chinese components before installing them.
Thank you so much brother!! I learn a few things with your video by using the multimeter specially for your detailedly explanation again thank you so much
Cool video...reminds me of my uncle..he knew all that since he was 15 years old back in El Salvador ,year 1975.he could repair anything back then..
58 years old and still learning, because i work 38 years on lathe machine. Thank you very much Tempatec
This video helps me as a beginner trying to learn how to troubleshooting faulty
Yeah, the way you explained them so easy to understand, I like you twisted 2 diodes to form a transistor. thanks for sharing and it's done well.
52 years old and still learning, Thank you
Me too,.and with old young 61 years.
What’s that phrase - Learning is FUNdamental? 😉
So many interesting things to learn too.
How to Mack aspotwelder with a micro-transformer
Its good to learn about basic electronics,but the truth is they do not teach of how to determine in bipolar transistor it is PNP or it is NPN and how to know by tester its pin is base,colecctor,emitter by reading not by position of a transistor or MOSFET transistor
HERMINO JALECO there are so many videos on that
Between you and Louis Rossman have helped me A LOT, thank you for this videos, im going to do the same but translated to spanish.

Even for me a hobbyist technician who graduated years ago, it is always something good to remember
Hello Ilike your video thank you people
Your way of teaching is too good!
Good- i liked way u showed things, especially the "joining of 2 diodes make a transistor"
Brilliant tutorial. Very clear and easy to follow, thank you!!
ive learned so much off your channel. thank you TampaTec
Highly educative and easy to follow
You sir are a legend. Best video on this subject that I've found.
63 years old and still learning, Thank you
sir i have learned so much watching these over the last few months

Thanks for this and explaining the diodes twisted together is like a voltage regulator and at about 2:38 it clicked for me.
I know this is an old video, but the information is still good. It would be helpful to know how and where to order replacement voltage regulators and transistors and diodes.
Thank you so much for your explanation it's very helpful .

thank your for video
Very informative and extremely helpful, thank you...
Good explanation thanks keep up the videos they are great and not long winded
I am enjoying your videos on you tube........Very Informative....Thanks
I wish I found these videos early on :c . Definitely the information I was looking for. Thanks much!
Great video...explained in easy terms!
thankou .tamp. you are teacher .my frend . - george Greece
Great,straight and to the point.
I liked how you did this video made it easy to understand thanks.
this is very good video, straight to the point.
Great video always wanted to learn electronics as a hobby this info is priceless
Thanks Brotha,
ps Now I can try and test my Halfer 500 amp
check parts on heatsink and solder connections like resistors
Liked the detail explanations, very educational Thank you
VERY helpful! I'm just getting started with troubleshooting, and that information was like gold.
u always help me out..thanks for your videos...
Do you need to removed them from the board? or can they be tested while been in the board to get a correct read
It's more accurate to remove parts.
@@TampaTec thanks for replying. I've been trying to learn more.
Is the diode reading .19v forward voltage really bad or is it a schottky diode which are typically around .2v forward? BTW great video! Thanks!
Made a whole bunch of notes on this, thanks heaps!
i like those videos you presented. Sir, kindly give us more or send us the video in trouble shooting in all parts of television and if you have a module on a CCTV sir kindly share it to us... thanks
good video sir i wana learn ic chips testing ....please do video for that...tq
thats very helpful but how about str transistor?
very good tips for board repairs
thanks for your helping to identify the transistor function...
Very Good.I love your videos and detailed description
ist so nice for me coz m on s same field , guide us for such a new models that the dnt hve this kind of a part. thanx
This topic should've been taught like this on college. I would've gotten A+ if it was like this b4 I graduated. :(
Well explained bro. 👌👍
thank you, good video i leaning something very clear explain
upload more video about electronic components now i can be able to fix something
good job a big help ....thanks, but would be better to hear you without the background music
OMG! Lifesaver! The section on transistors was a great help!
Thanks tampatec I live in Australia your vidoes are the best keep em comming
Good simple testing. Great. Thanks
Hello! Thank you the teaching. Is it necessary to remove the components from the circuit to do this tests?
Another very useful video. Thank you!
Thanks I have learned something today
I am learning a lot. thanks
Cool ng very smart video,also someday how to repair like u,,
