It's an IGBT problem, not a TTL problem. Thanks for the video. Edit: just a thought, the Yongnuo's are generally copies of Canon flashes; and, the YN560IV's had a similar flaw where arching destroyed the IGBT (Canon had the issue and Yongnuo copied their flash) So you also need to make sure the flash bulb is centered correctly and the rubber ends cover well to stop arching. Also make sure your solder joints are good :) Hope this helps anyone else having this issue.
@@Marko-od7eb I was ordering TO-220FN. but it did not matter as they used to work for 5 minutes, sometimes a day, once was working for a week and had to be replaced again....
@@Marko-od7eb TO-220 is the package - how the component 'looks'. Buy from Digikey or Mouser for good parts. They are not expensive - but shipping can be.
I've used it for 1500 photos until now and it's working fine. Thank you again! I can't believe that's it's working.
I am glad I was able to help 😊 around $40 saved 😊

I'll try tomorow. Thanks for the tip.
thanks mate i have the same problem, good to know its easy to solve
hope yours will work fine. in the end I just bought another two flashlights
Is there a particular place to obtain the semiconductor required
It works. Thank you!
Can you put link for part in comments. Thanks
So what is the part number ?
if you would watch the video, you wouldn't ask this question 😅😅😂

I did but there is so many RJP4301's.
What is the IGBT model ?
Is it TIG056BF or is it TO-220FN ?
