Question about Computers & Internet

On and off

Hi there,
I have a Toshiba Lcd monitor.
When i power it up,the toshiba logo blink in for a half second then the screen goes to blank,and after a circle begins,with power led change to green-the display flash a little bit,then the power led goes back to orange,and nothing happens even if i connect a vga source,or if i disconnect from power.
BUT,i take it apart,and played with the inverter sockets,which brings the power to the backlight,and after several plug ins and outs,the backlight burns in,and the screen worked correctly.BUT if i disconnect the power suplly again,the same ciclyc thingy begins.
And if i listening the board very close,i hear something discharging,and i thought maybe the inverter not have enough power to burn in the backlight,and when i plug in and out the sockets,maybe it left a small electricity in them to easily burn in next time.

If any ideas,thanks!

Sounds like it is shorting out. Do a voltage check on the power source.

Screen wont turn on


Have you checked your computer? Does it turn on when you press the power button? Does the power button or lights in your computer lit or is it blinking? Can you still see the Toshiba logo or nothing (just blank)?

You have two possible issues here:

1. Power issue
2. Computer part problem.

You need to check both. Start with power issue. Check if computer is getting any power.

When I turn my Toshiba A45-S151 laptop on, I first get the screen that shows the Toshiba logo and has the four icons under the logo. Usually the next screen is black, has a cursor in the top left corner,...


That blinking cursor is the way in which the BIOS is telling you that Windows is not loading because its most critical, core files have been corrupted beyond repair. The only thing you can do is to reinstall using the recovery cd or your own Windows install disk.

Black screen


Sounds like your screen is being switched to "Power Save" mode due to inactivity. This should switch back when the mouse is moved. This can take several seconds on a laptop. You can remove this "Power Save" by right clicking anywhere on blank desktop, select "Properties", "Screen Saver" and "Power Settings" then select "Always On" for the monitor.

Monitor displays breifly then goes to blank screen


The power -inverter board probably needs an overhaul.
I redo many of these.
If the screen was pinkish or flickering before it finally got to this point, it is possible that a bulb has gone bad.

BLANK SCREEN


i think your system has crashed so you need to do recovery or do a fresh installation of your operating system. Your system is unable to boot due to corruption in system files.

You should be able to locate a surface mount fuse at your local electronics store.
