The fact of it acting differently depending on the power source makes me think you may also want to try the following and see if it helps at all.ДЎ. I am pretty sure it will show fine, as this doesn't seem like a GPU problem, but can't hurt to check. You could try attaching an external monitor and see if it shows well on that.

Who wants to spend the money if they don't have to. I dont mind getting a new LCD screen but I want to be 100% sure the screen is the problem.

If I tinker with some drivers it makes the screen act a little differently(a little brighter or starts flickering). Nothing so far worked, key observations are: that if I change brightness the screen flickers and if I remove the AC power source the screen almost becomes unreadable faint. I tried adjusting the brightness with BIOS FN keys I tried to uninstall/delete drivers and reinstall

Im pretty sure the issue isnt with the cable but I'll switch back to the old one again tonight and see how it goes. Im pretty sure the cable is the right one(I ordered it from parts people with the right model name) but I reverted back to the old cable and the issue still persisted. If not, then I would make sure that it is actually the right cable for that device. First try disconnecting and then reconnecting the cable (both ends) and see if that resolves it.

Sounds like the cable either isn't the right one, there is a fault in the new cable, or the connections are not correct. Your help is greatly appreciated and thanks in advance I'm writing this from my laptop but staring at a dim screen **bleep**. Do I just order a new LCD screen and will it solve my problem? Not enough power is reaching the back Light so Im not sure if the problem is with the screen itself. I didn't do anything crazy when repairing the laptop plus the new cable works. I think this is a power issue but I have no idea where the problem is.

Its not a driver issue I tried uninstalling all drivers and even did a factory reset to the computer. You can barely read from it(almost like a broken inverter but screen doesn't even have an inverter). The screen instantly becomes almost black when I remove AC power source. Screen stuck on very low brightness and flickers when I try to adjust brightness myself(FN keys or change power plan) screen would flicker every time I move the screen or it would go black completely This happened after I replaced a fault LCD cable on the laptop because it used to Flicker every time I moved the screen. Very dim screen but the laptop is still in a usable shape. It will take effects quickly.My Laptop(Dell Inspiron 15 7559) is stuck on low Brightness. To resolve it, open the Intel HD graphics control panel, go to Settings > Power, uncheck power saving mode, and click OK button. However, if you have done the above method and the Maximum Screen Brightness is not working at all, the problem is caused by the intel hd graphics setting.
