Hi, I need some help please.
I have problem with my screen. it’s a back light issue and if you put a strong light behind the screen is working perfect. I recently changed the LVDS cable but I have the same problem!! Does anybody know what to do??
I know that if you change the full screen is very expensive.

At this point I’m not sure if your logic board has a problem or not. If you had a liquid spill you likely damaged the Inverting Converter Linear Technology LT3957 B29255 and/or its support components. I’ve circled the chip area in question on the back side of the logic board. Here’s the Fixit guide you’ll need to follow MacBook Pro 13" Retina Display Mid 2014 Logic Board Replacement
You could also have damaged the LVDS connector on the logic board by spillage as well.
While rare the LVDS connector within the display assembly could be damaged. As you replaced the cable you could have damaged it or the logic board connector.

@skarseras On top of the fact the screen itself is very expensive, it might as well not be the solution to a no backlight issue.
As @danj pointed out it might be a logic board issue, but I would not recommend buying and replacing the logic board either unless one can rule out a bad backlight within the assembly itself.
Any DIY solution may turn out to be potentially useless and very expensive. Your best option in my opinion is finding a reputable lab experienced in component level repairs that will be able to verify what the problem exactly is and take care of the repair if the logic board is faulty.

Why did you replace the LVDS cable?
Did you have a liquid spill or sit your system down on a wet surface?
