Found this information so far after quite a bit of searching but it would be good to find an available pdf for the IC
The circuit looks very similar to that of the SSI_400_14A0 inverter board

Hi RJ,
That's the problem I really don't know. Searching the internet people have offered other equivalents but they have a lower pinout count so I'm still looking.
Thanks for the pdf for the SEM2007. Interestingly it does has the same pinout count.
Cheers
Edit
I think the SEM2007 may well be a lower power version of the SEM2107. Looking good thanks.

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...
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

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.
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...
