My cheap crappy 1KW grid tie inverter (GTI) seems to keep blowing IGBTs. When I first got it, it had two failed IGBTs. It used four 60N100's (TO264). I bought 5 from a dubious source (fleabay) and replaced just the two that were dead. The GTI worked for almost two years but recently one of the two that I replaced failed. Since I had three spares, I replaced the dead one. Then a few weeks later it failed again. Weird. Well since I bought dubious China-sourced IGBTs from fleabay it could very well just be a mixture of fakes. I replaced it, but then a day later it failed again! I put in the last...

Hello, this is my first post and im just a beginner, so be easy on me guy. thanks
i have a LED chandeilier that switches colors from white to cool white to warm when toggling the switch, it has 24 LED arms, each arm is 30 CM length.
i have no datasheet at all for the LED lights, all i have is its length.
long story short, testing the chandelier on the ground, and it works fine for 1 - 2 - 6 hours, no problem.
as soon as i fix the chandelier to the ceiling and bury the driver inside the hub,... -
Problem
Fixing a dimming zone TV with LEDs not lighting up. Dimming zone circuit introduces added variable to diagnose LED and/or Dimming Zone Driver board? Some 1/2 rows of LEDs appears to be out in active dimming zone off AND some brightness flickering with active dimming zone high while playing changing video
Model & Board Pics
Conflicting Spec
Vizio indicate this TV has 10 dimming zones. However, LED strips and Zoned light driver connector suggest 12

Need Audio Driver for Thomson P14C4BK128 (Windows 10/11)
Hi everyone,
I'm looking for help finding the correct audio driver for my Thomson P14C4BK128 laptop.
The sound is not working properly, and I believe the audio driver is missing or not installed correctly.
Here are the details:- Model: Thomson P14C4BK128
- Operating System: Windows 10 64-bit
If anyone has a working link to the driver or knows where I can download it, I'd really appreciate it.
Thanks in advance for your help! -
I just got this tv today and it appeared to have no backlight on. After taking off the rear cover and checking again in the dark I can see that MAYBE one quadrant is lit.. But still it's quite dim. I was going to check the LEDs with my tester, and I found LED 1 and LED 2 + pins on the wire from the inverter, but I couldn't identify a ground. Nonetheless I tried using a mounting screw on the inverter board and also the chassis as ground but regardless my tester reads 300 which is what it reads when there is no voltage draw.
I don't know how exactly to test the inverter itself. Is it...
