This video shows how to repair a smart TV that has no power. power modification. tips and tricks. Please like share and subscribe. thanks. Happy New Year to all!.
This is by far the best tv repair channel Thank you very much for sharing your knowledge Maybe sometime you can make a video explaining with more detail this modification for beginners like me to know what you are taking off from the board and why Thank you and i hope you have a great 2024
Excelente video y gracias por compartir sus conocimientos con la comunidad!! Ahora una pregunta, porque al modificar la fuente saca las 2 resistencias asociadas al octocoplador, y el diodo zener??
Hi there Tevz, I noticed that you removed the 2 surface mount resistors connecting the opto coupler to the rest of the circuit and installed a 10nf cap in parallel across the two pins of the opto coupler. It's the first time I have seen you doing this. And I watch all your videos. Have you changed the way you do the modification or am I sleeping...?
I added the ceramic capacitor because there is a resistor that is series to the optocoupler and I removed that resistor. the optocoupler now has no capacitor, In some of my videos I dont add ceramic because the board has already a capacitor. see this really needs a capacitor. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-61JtodOaMvQ.html
Very good, but I want to ask between str6053 and str6252 are they the same because is only str6252 are available in my area right now, your response pls.
congratulations. The last work of 2023 has also been successfully revived. We are looking forward to seeing videos that will be helpful next year. thank you
Hello master, I am working on the same TV board, the FET transistor is faulty and I have replaced it with 6053s. Now the secondary voltages seems to be low, I am getting 3.1v and 12vdc for the screen side. Could it be the chopper transformer is defective? My vcc voltage starts from 15v and becomes stable at 12v. Please any suggestions?
He has a Skyworth model 55UB555S that does not work, and the view on the motherboard shows the transistor is broken. Can you find out its number, as shown in the picture?
I've seen all your power modification videos, but I've never seen you remove components the way you did here. Why do you have to remove them? Won't it work with those extra components you removed? I understood why you had to remove the 2 resistors in series to the optocoupler, you didn't have to add an external capacitor again if you didn't remove the resistors because the capacitor was already there. Why did you have to remove the diode from the board?
Hie wish you a happy new year sir ! Can i use this str on a 55 inch power supply also should i remove those resitors you took out near the optocupler also is they a similar modification on dual mosfet power supply thank you
I can say today is a nice day to me ! for finding and learning at your technical school . I am attending with big focus and attention of my mind . many thanks ! Eng. Tevz
Hello thank for the 2023 videos i enjoyed. The resitors you removed near optocupler must be removed on all power supply?also can i use this on 55 inch power supply.is they a similar similar modification on dual mosfet power supply ?
I've got an issue with a Samsung 32 inch TV Model LE32R88BD, has standby, comes on with audio of static for 1 second, followed by loud crackling noise on speaker and immediately dies, I've inspected the boards, nothing blown, no shorts. Noted some SMC aluminium caps at 1000uf 25v look a little domed. I removed the logic board shield and saw 2 more with a dark grey circle above them on the shield, if I left the set long enough it will come on. Also would you say a 470 uf 25V capacitor tests as 399 uf is bad?
@@tevzTVTevatronics remember the 32 inch Samsung TV I was attempting to fix, fixed it. The caps under the shield on main board were toast. My first ever TV fix.
