I have been using DELL Inspiron 1545 since last 2 years but had never faced this problem before. The monitor is fluctuating and sometimes the screen goes off. I have to adjust the panel so that light comes back. And when i am pressing few side places on the back side of the monitor liht comes andwhen i leave that part, light goes off again. This is when i am not charging.
And when i charge sometimes, the light goes off or fluctuates even if the monitor is working fine.
Please help me in understanding what is the actual problem behind this?
Sounds like a cable is coming loose - most likely behind the screen. Reseat that end of the cable.
