I’m not sure of your image sources as I do see a bigger issue! The display connector is also damaged.

The component you are pointing to is an inductor L9000 FERR-250-OHM

This is part of the LCD backlight logic. Unless you physically damaged it, it often gets damaged when the cable is reversed and often a few other components get damaged with it.

You really need to get your hands on the schematics and board views to properly diagnose things using a digital multi-meter and lastly have the needed soldering tools.

thx at first I already think I found the right indicator, but unfortunately I only replaced this with a wrong one which caused the display for paaar secunds to work and after that it went out.... I think something else broke because after the new replacement the screen doesn't work like the first attempt, so the question is, how do I find out which part is broken now?


I have a mutimeter, but I don't have as crass experience with how I can find out the error, I'm looking forward to a few tips


@linus97 - Think of it this way ....

You need to drive to someplace you've never been! Just jumping into the car and just driving the edge of what you know and just keep going won't really get you to where you need to get to! The better direction is digging out the road map identify your location and the one you want to get to and take notes on the pathway. Basically let your finger drive it first!

So you need to do the same here, get the schematics and boardview drawings and using your ability to read them and using the tools you have (or need to get) trace out the logic.

This is not an easy process without a good understanding on how digital electronics works.


I have come to a point where I can no longer make progress. should you have time, can make a video call?


@linus97 - This is a point when we all reach out skills limits - Even me!

I really can't help you over a call, that's not really workable.

Remote surgery failed for the exact same reason. Robotic surgery overcame some of the pitfalls, sadly, it's still limited as the person doing the work is not able to respond quickly or feel things directly.

Time to button things up and get your system to someone with the needed deeper skills who can fix your logic board.
