I have a Dell 15" TFT LCD monitor (E153FP) which appeared to stop working recently. It flickered for a while and then went black. However, when you look close it is displaying the images but not being lit up. Therefore it must be something to do with the backlights. Also, I took it apart and there seemed to be some black dust on the power circuit board.
I can't afford a new monitor and can't really afford to take it to a repair shop.
So, the question is does anyone know how to fix this problem? I have little to no experience in circuit board electronics but I reckon I would be able to pick it up with a good walkthrough.
Thanks for reading my question and hopefully you can answer it!
