Thanks Mr Tevs. Very clever to be able to do these repairs even though you don't have the right component available. Thanks for the tip about the optocouplers too. Best wishes.
Glad to help, and welcome back.
Thanks from India gujarat
How can we detect VCC cap. In anybody paowersupply please
Thanks for english translation/talkover.
Good evening sir , I'm a technician, am John Linus, I love your work, and will like if you can help me I every fault that I face here
Also have Samsung TV with no signal
pinagbbwal na teknik pero pwedi
How to repair tv with horizontal lines
I think changing the fuse with resistor is not safe practice. Safety fuse is a primary protection when there is short in your circuit. Changing it with resistor just limits the current in your bridge rectifier due to your bulk capacitor inrush current. So it is better to keep the fuse untouched when doing test to safely prevent damage…. Nice troubleshooting tips though, thanks for the video.
Good day sar, Thanks so much for this keepup,
Always welcome
How about fixing this module on a power board with more than one MOSFET and more than one chopper... Can it work?
,hi sir my led tv lining on screen with picture plz.solution problem
Lines on the screen is mostly a panel fault.
SUPER DUPER BUT.SIR GIVE ME STR DIAGRAM PLZ😊😢😢😢

Sir tecz bk pwede dumalaw sa shop
Location po?
Sir, you are the master in led tv repairing, you have a thorough knowledge of circuit, keep it up thankyou very much,
Thanks and welcome
Hi where can I get circuit diagram for lcd,led tv thank you
sir, there is a tutorial for making a CAPACITOR DISCHARGER....thnks
use resistor, 220 ohms to 4.7k ohms will work
@@tevzTVTevatronics , Can you make a video on how to assemble it?...thnks

Hello sir
Strw6053 is out of stock here. So can I use strw6052.
Thanks for the advice.
Yes you can
@@tevzTVTevatronics 🙏 thanks you so much
Hi sir i hav dadson lcd tv in primary section blown SMD Transistor No. 2A ) and IC no. 273H35 and MOSFET No. tk11p65w these components doesn't available in electronic market, any solution? Thnks sir
3:21 what is the value of discharging resistor? Ohm& watt ?? Thanks Tevz
Good day sir, toshiba din na board 4 ang opto coupler saan kaya banda ako mag kabit gamit ang 4wire.. pwde ka hingi nga contac number?
Good morning sir I need help for Samsung microwave key pad not working I think have problem for board
Great job and thank you any advise on a Asus Rog Swift 27 inch curve monitor problem is flickering and white lines tnx.
Hie so the str we can use it on any size of power supply ?
upto 180 watts
sir what pin of opto coupler did you the wire of str6053s
Este compa hace milagros, asi trabajabamos en la teles de bulbos en otros tiempos , un corte aqui otro alla una pieza de otra tele y voila!! teniamos tele para otros 20 años.....
Smart man!
Good luck with you and Thank you Very Much ❤❤❤
Nice video, always tell people to subscribe to your channel because people dont know subscription is free. Thats the reason most people dont subscribe.
As for the right optocoupler to connect, i usually trace pin 4 back to the PWM IC pad. Ive never tried looking out for 431.
Im still wondering why you always use the 220ohms 20watts resistor. Whats the effects if i dont use it? Is the fuse not means to blow out when theres a wrong connection? Why put resistor that will not blow? Or will the resistor blow?
Once again thanks for your video i now know how to modify power supply.
Though i tried it on one power that has a different pwm ic about 16 or 18 pins
Hi the restor is the to prevent more compounents from blowing it limits the current I use a dimbuld tester so if there's still a short the light lights up bright
@@reaganlewis9074 wow, thanks, but will the resistor get damaged?
Nope just use a high wattage resistor
@@reaganlewis9074how much ohm's and watt resistor for discharge Main filter capacitor ? Thnks
@@kishanpreston1533 220 ohm 20 watt resistor
mr tevz do you have a telegram channel
Amigo puedo hacerle una pregunta espero me ayude. Los transistores 30F124 o los RJP63K2 se puede medir con tester en la escala de diodos. Estos dan una lectura de un lado y si volteas las pinzas no da lectura en pata 2 y 3 y al activarlo mide un valor más bajo estaría bien el transistor si da un valor en tester. Gracias

very good video and very nice explanation. 👍👍👍
The best tv engineer, keep it up Sir,
Hi friend thanks for another informative video
Let's subscribe people Mr Tevz channel is the best i can now modifie a power supply with his knowledge using str thanx a lot Mr Tevz god bless u Mr
Wow, thanks
Thank you sir teva
excelente trabajo, saludos.
That's a good work Mr. Tevz. Your explanation about your process is very good explained. Thanks and blessing 👍👏🙏
You are very welcome
Tnx! good lesson!
Very nice your video sir
Good job mr tevz👍👍👏👏
Thanks 👍
Give a modification ic for active pcf circuit.....the pfc 8pin chips are mostly not available for purchase
First like😅

Like always nice work
thanks 👍👍👍
Nice new multimeter ❤
Thank You!
Perfect
Great
GOOD 👍👍📺

Great work
Wow❤
Great video again,thanks bro. And please add Turkish subtitle support to your videos
Turkish subtitle is available
@@tevzTVTevatronics You are great,thank you so much.
Good morning Tevz. Your are master. Great job. ❤️
Please can you send me the diagram for the ic strw6053.
Because I sightly didn't understand the pins soldering.
I know you have many videos on this ic.
Thanks ❤️
Check my other videos. About STRW6053N modification, There are more datails than of this video.
@@tevzTVTevatronics yes I did check some hours ago. Now I understand fully how to work with strw6053.
My confusing was only the pins.
Infact this ic have 6pims physically and when you look into the diagram you shown on other video. There no pins 2.
You have 1 3 4 5 6 7.
That's was my confusion always.
Pins 5and 7 for ground.
6 for fb.
4 for vcc
3 source/octo
1 drain
@@Fardeenfarwest Yes there is no pin 2.
@@tevzTVTevatronics right and that's was my always confusion. Now it's clear. Thanks.
gracias ,por compartir sus conocimientos..
Congratulations master 💕💕💕💕💕💕🥰💕😊
Super modifications.. Sir
Thnkz for sharing sir tevz
Always welcome
Hi sir send how to str concerned digrams

Hey tez I have a question
I have a Samsung 40 " that has fault of backlight,once I replaced the backlight they worked for one week and wete blown again,,,the power of the backlight is 227v,, how will I solve this problem
@@stevohtheeman6161 Did you replace them all? Adjust the backlight level to 50 percent.
P.w.ic not found how to connect str wiring please
Check my other videos about power supply modifications, some have a diagram.
Sir tevs pahingi po diagram nung regulator ic
