I assume that your laptop's display has been damaged. Are you sure that other things are working normally? If other components are working, then problem will be with the display unit. Try to repair or replace with new one.

Using a TI-84 Plus Silver Edition and the screen just went blank in the middle of a class. changed the batteries, didn't help. cleaned the connectors, didn't help. tried to change the resoluti


TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.


What do you mean by "changed the resolution"?

The part that supplies the power to the screen is gone. I recall is is called the 'exciter'. They can be replaced, so take it to a computer repair shop. Same thing happened to my Toshiba.

Have this check to your nearest brand service center. There might be problems on the video card. This might be due to excessive heat that is frying the parts of the laptop. This is a common problem for Toshiba laptops. Kindly check the exhaust if there is a clogging dirt, this is the main reason of excessive heating aside from the prolong use of your laptop. My best advise is go to the nearest service center.

HP Pavalian laptop screen gone black and blank.


It seems like the lcd back light may have failed can you see a faint image on the screen when you look really close, try it with a torch. If you dont see even the faintest image the inverter has failed and needs to be replaced. If you look on youtube again and search for videos of replacing both the back light and the inverter it will give you some info on how to change them. Do a google search for hp spares and you will probably find what you are looking, i think the inverter is about £30 and the back light is bit cheaper. hope this helps.
