If your Dell 1908FPb monitor won’t power on and its buttons don’t respond, unplug it, hold the power button for 30 seconds, then reconnect power. Try another power cable and outlet. If still dead, the power board or control buttons are faulty and need professional repair or replacement.

في بعض الأحيان لا يتم التحقق من أبسط مشكلة! تحقق لمعرفة ما إذا كان مقبس قابس مختلف يعمل أو اختبره باستخدام جهاز آخر. إذا كان الحبل قابلا للإزالة، فحاول استبداله وكذلك تأكد من أنه مثبت بالكامل في اتصاله بالشاشة.
أخيرا، ركز على دائرة الطاقة للجهاز إذا قررت فتحها كما هو الحال من وصفك، فإن نقص الطاقة للمنطق هو المشكلة الجذرية. ركز على مزود الطاقة ومنطقة مفتاح الطاقة أولا.
Sometimes the simplest issue is not checked! Check to see if a different plug socket works or test it with another device. If the cord is removable try replacing it as well as make sure it's fully seated in its connection into the display.
Lastly, focus in on the power circuit of the device if you decide to open it up as from your description the lack of power to the logic is the root issue. Focus in on the power supply and the power switch area first.

This happened on my Windows laptop once, the touchpad and scroll buttons both stopped responding. A quick driver reinstall fixed it instantly. Might be worth checking in Device Manager.

Don't think that will help here as this is a stand alone display not a laptop
