Check the power supply on the rear..is the fan blowing..if not, the computer will overheat and not start
have you added memory that isnt compatable, if so , remove it and try to restart
have you updated anything recently? is the large main battery completely in it's slot? new USB device?
check a few of these things and post here again , i will help you all i can..

Unfortunatly you do have dead pixels, but you cant fix them. Lots of lcd displays have them, some are more noticable than others, it dosent mean your lcd monitor is going to fail soon or anything like that, even brand new lcd monitors have dead pixels it is a comman anoying problem with them.

connect an external monitor on the unit and press the key combination to get the video on an  external monitor this is different on some laptops on HP dv 6000 for example it is FN F4 if external monitor work the problem is with your laptop display if the external monitor doesn't work its probebly your systemboard als check your memory.

I got one of my buddies laptops trying to fix it for him. It is a toshiba p700. I'm thinking there is something wrong with the screen. I don't know much about computers but when you press the power button,...


one thing you might want to try first, is to connect an external monitor and see if you see things, if you do, most likely your screen will need to be replaced. Probably the back lighting bulbs are burnt out or the inverter is dead.

thanks

My emachines monitor has no picture, hard drive is functioning properly. Monitor is black


if you do not get a screen with a LCD monitor its likely you have a inverter problem or BACKLIGHT problem. you might need to replace the LCD backlight or replace the monitor on the desktop.
check to see if the laptop can get a picture by plugging in a monitor to it, im sure theres a connection for external monitor.

theres also a FN (function key) command to switch from lcd to external monitor. always test before commiting to replacing a monitor.

The desktop, you might want to test another monitor on the desktop just to be sure the monitor is gone or dead. if you see on the monitor a OSD saying "No power or No Signal" or you can pull up the OSD(on screen display menu). then the monitor is not dead.

might be the computer even though the computer powers up doesnt always mean the computer is working.

i would check the motherboard for blown capacitors or funky smelling(burnt plastic)aroma. Make sure the computer is off before checking.

get back to us!

thanks

Toshiba Satellite P25-S5092/ Computer will come on, but screen will not work. Wondering if it is most likely the LCD screen itself, the backlight or something else.


Hi,

If you have deduced that indeed the Toshiba Satellite P25-S5092 will boot and therefore operational except no display on the screen, you can always verify by connecting an external monitor. You of course would need to press Fn + F? (the F key with the small monitor icon).

As to the LCD screen having no display, often this could either be the CCF lamps (cold cathode florescent) and/or the inverter that powers it. One way to verify this is by shining a flashlight obliquely to the screen and a portion of your desktop would show albeit very very dark. Often, it is the inverter that fails. In some instances it could even just be a cold solder, loose connection or capacitors that have dried up, leaky or blistering.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
