Ok so I changed the Screen in my Toshiba laptop Due to the old one being Broken of course. Now the strange part is I have to plug the old screen in when I boot the laptop then unplug it and plug in the New screen after it starts for the new screen to light up?? I don't Know why. Then on restart the new screen is blank. Unplug it and plug in the cracked screen and it lights up then plug the new screen back in and it works perfectly! The laptop is Toshiba C655D series and the screen is a 15" LCD the no Inverter style. Any ideas would be gladly appreciated and thanks in advance!

If you are looking for a laptop fix...The cheapest route will be a new laptop altogether, as it sounds like it was not completely the old screen that was faulty, and may have been your laptop.

A new laptop is also a better investment, as it will likely be better than your current one, and will have a new cycle of warranty.


I understand this option may be outside of your budget, but from personal experience, laptop major component repairs are often more trouble than they are worth in terms of price, certainty that a new part will be the solution, and what you may have to pay for installation or the time it requires to do it yourself.

Thid is actually a repair for someone, and yes they can't really afford another laptop, I am very good and soldering and more difficult repairs so if you might have and Idea of what is causeing this I'd be greatful for any ideas. I was leaning towards the lid close switch but in this laptops case its a magnetic soldered part on the mother board. Would removeing this maybe help or I also have another motherboard I'm considering swapping out to see if that works. Or I am leaning to the new screens control board on the back maybe being fualty, not letting the laptop realize its plugged in at start but any other ideas again I say would be great! Thanks again.

Brandon, are you plugging the screens in as the computer is powered up? I would recommend against it. Also, if you have an external monitor try plugging it in with the new screen installed and see if you get a picture on either one. After the laptop is powered up try tapping FN+F5 to see if there is any change. Lastly, did you verify that the screen is the correct one? I am in the process of fixing the same laptop but screwed up the numbers and have to swap out the screen for the correct one. Good luck and let me know if you need any more help.
