How to identify the right optocoupler. " Power supply Modification"

[@bobs_ya_runkle]

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.

[@tevzTVTevatronics]

Glad to help, and welcome back.

[@tevzTVTevatronics]

Wow, thanks

[@dexternierva5433]

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.

The best tv engineer, keep it up Sir,

[@owaisakhter2673]

Engineer doesn’t do this kind of alteration. Engineer always find the actual source of problems and rectify it with proper solution. This guy just altered the circuit with non professional substitute which is not long term and proper solution. He is just another repair guy.

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

[@reaganlewis9074]

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

[@sylvalineresources9540]

@@reaganlewis9074 wow, thanks, but will the resistor get damaged?

Nope just use a high wattage resistor

[@ArshadMehmood-kz6ez]

Please tell about pin 6 BR But pin 6 BR mean Brown in and Brown out starts operation (brown-in) when the AC input voltage is above a certain voltage, and stops operation (brown-out) when the AC input voltage is below a certain voltage. That function you made bypass connecting with Ground.

[@electrolatif]

Nice new multimeter ❤

[@diegledw]

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

[@lightshine6044]

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 ❤️

[@tevzTVTevatronics]

Check my other videos. About STRW6053N modification, There are more datails than of this video.

[@Fardeenfarwest]

@@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.
