Question about Posiflex Computers & Internet

1 Answer

Dark screen Hi! I'm having a problem with this terminal. It works and at some point there is a black screen. I can't see the icons at the desktop. After a few seconds it's fine again. I tried to connect an external monitor and everything is fine at the second screen. When it's black and I touch the screen I hear the sound of touch. It might be a problem with inverter or the backlights? Please help. Regards

IT is the inverter. The backlights usually turn the screen orangish color before they fail.

SOURCE: my hp vs15 lcd monitor

It does sound like a back light issue. Not under warranty?

The fact that it does light up suggests it may be a heat induced fault? May be just a simple dry solder joint. Although you cannot rule out the CCFL (Cold Cathode fluorescent lamps) being faulty either. A quick check with a meter may tell you if it is the light source or the driver cct that is at fault.

If its the lamps, salvaging some from another LCD may be a good cheap altenative.

Usually there is a simple fault (failed FET/Transistor) causing these problems so if you are good with a soldering iron and can work thru the cct to locate the offending FET/transistor it will be a relatively cheap and easy fix.

My screen is black on my gateway w340ui what needs to b repaired n how much?


Screen is black? Does it look like the computer booted up all the way, if so maybe your icons are on the desktop.

Shine a flashlight on the dark screen to see if you barelysee the icons on the desktop. If so, then the LCD Inverter is bad.

Plug in an external monitor and see if the display shows up on it. It can beany kind of monitor even the old big fat crt monitors as long as it has a vgacable to connect to your computer's vga port. If so that proves yourvideo card is ok. The video will show on most systems when you rebootwithout you having to do anything. Some systems will require you to hit the FN(Function key) + F1 thru F12. Hold down the FN key then hit the correctkey for displaying on the monitor (F1 thru F12). The correct key willnormally have CRT/LCD on it or it will have the icon of a display.

If you see no icons by shinning a flash light and the external monitor works,then your screen is bad. If you see no icons by shinning the flash lightand nothing shows on the external monitor, then most likely your video card isbad.

Hi, I have a T400 and when I trun it on the Thinkpad black screen appears and does not change. Please can you help


Does it seem like the laptop is running except the display is black? Do you think it booted all the way except the screen is black? Do you hear fans running, disk drive spinning?

Screen is too dark


If you can see the icons but the screen is mostly black ( you have to look real close to see the desktop or windows logo) most likely you need a new lcd inverter. I repaired a 1300 series laptop, that had a dark screen, not black, just darker, and the fix was a new motherboard. That would be the second option if replacing the lcd inverter doesnt work. Lcd inverter is about $10 Motherboard is around $50-65 for that model on ebay.

This solution did not work for the HP dv6000. The screen is black.


Have the lamp checked out on the screen. Also make sure that the dark and light key is not set to dark. Press the fn on the keyboard hit the sunny icon.

Hard disk icon disappeared from desktop


To add the hard disk icon back onto your desktop, first click the "Finder" button in the dock. It is the dark and light smily face icon at the end of the dock.

Next, click the "Finder" menu item at the top of the screen and then "Preferences". In the "Finder Preferences" window that opens, click the "General" button. From there you can select what system items appear on your desktop. You can click "Hard disks" to re-add the hard disk icon.

Vista problem


select on the keypad the 'Fn' button, keep it pressed then normally on the lower right of the keyboard there will be keys marked with as olid star shape or an empty* shape or similair, while pressing the Fn key press one of the star iconed keys to up the brightness.

If still dark then the backlight on the screen needs replacing by a qualified repair shop

LCD Display Blank


I have a sony cybershot DSC-S650, the LCD was very dark and could not see anything except if I pointed it at a bright object, everything else worked ok. I could take pictures but could barely see them in playback as well.

I took it to Sony authorised repair outlet and was told the CCD was damaged, they charged me USD $55 to repair it (in Quito, Ecuador)
