I decided to give this a go, I ordered some led strips to go in the 40in lcd. Would the 24v that feed the inverter board be enough to run the strips or should I add a led driver board? Should the strips be wired in series or parallel?

Re: Ccfl to led conversion
The 24v will power the LED driver. https://www.aliexpress.com/item/32972760374.html

Greetings everyone,
I have a HANNSG Hi221 monitor that exhibits two seconds to black issues (backlight goes off, display is still on as confirmed by shining a flashlight on it) with some additional oddities...
The monitor failed on me with a standard "2 seconds to black" some time ago prompting me to initially replace most of the electrolytic capacitors (some of them were bulging/leaking).
Things kinda sorta worked for a night, then the problem returned along with some flickering and "buzzing" noises.

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,... -
Ok.. this is the story:
Have an old Samsung LED 3D TV (UE55F6475). First it started to lose light on the lower 40% of the screen now and then. Like for 10-60 mins and then it would work again. Then a bit later it just got stuck in that position. The lower 40% of the screen is dark, and it gets progressively darker the lower u go so it's obviously that LED strips where not working. I also looked for similar errors online and saw an exact copy and on that one it was faulty LED strips.
This is kinda how it looked, just that mine were at the bottom of the screen:

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

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! -
