    You don't have to get a new screen. It happened tp me a week ago. I tried to buy a replacement LCD from a shop that is compatible for my unit but none of them worked. Then I tried to bring it to an electronics fix it shop, they just disassembled the parts and solder some things connected with the backlight and it was fixed.

So laptop will power on, however the screen remains black, or off. The power cord and battery both are in good working condition.


Take a very close look at the screen. If you can see a faint outline of what should be on screen, then it is the backlight that has died; you will need to replace the screen. Try your brightness settings as well.

My Viewsonic VA1912wb-3 Is not in worranty.. But I am suffering to problem that dark black screen with no diplay message. power supply is ok. pls help me to solve on my own..thank u


Most likely, it's a backlight or backlight inverter issue. (The backlight itself usually fades or makes the on-screen image change to pink/red.) With a bad backlight, you'll usually see a very dim image if you look at the TV from an inch from the screen. Block the room light from overwhelming this image (sometimes a carefully positioned flashlight will help you see something). If the inverter or video board is bad, you will see nothing. For an out-of-warranty TV, open up the back of the TV and remove the shielding. Look for any scorch marks or bulging or damaged capacitors. (Sometimes other parts will fail on this part but these can be spotted easily. Capacitors look like cylinders on a tripod.) The scorch mark and smoke may indicate a resistor or zener diode that had been used as a fuse and is now gone.

If you borrow (or have a) high-end multimeter (able to measure high frequencies - 50 kHz) or an oscilloscope, hold the multimeter probes a fraction of an inch apart about an inch above the inverter board and power up the TV. If you see a 1 or an actual value, you have a good inverter. If you see a reading near 0, the board is bad or the multimeter can't resolve the frequency.

In either case, you can buy a replacement inverter for $50-150 and just do a simple swap. Disconnect all of the wires (connections are similar to molex and ribbon cables in a computer) and remove board (a few screws usually). Connect the cables to the new inverter. (If you google backlight inverter replacement, you'll find videos and text descriptions.) Note the part number on the board, including the Rev number, and order the exact one (shopjimmy.com or lcdparts.net are good starting points). Universal inverters do exist but can result in reversed controls (up to lower the brightness). Replacing individual parts on the board is cheaper but more prone to not tracking down all of the bad parts.

If the inverter is good, then it's probably backlights themselves (several in most TVs). These are sandwiched on the perimeter of the TV (usually under some tape that holds the lamp, reflector and other parts together. You need to order by length and width and get ones for your TV size. Separate the panel from the bezel. Remove the tape, and separate the reflector (make a note of how things are put together) then you have to Dremel (or use another rotary tool) to remove the plastic to get the backlight out. (They are often molded into the frame.) Then put in the new backlight and reassemble everything. See http://www.lcdparts.net/howto/default.aspx for more information but for an overview: http://www.inventgeek.com/Projects/BacklightFix/overview.aspx Then push the new backlights into place, reconnect the wires and close up the sandwich of tape and other parts around the screen. Then replace it in the bezel.

With a good spare backlight, you can test an inverter for condition (plug together and turn on the tv while the box is open). Similarly a good inverter can test the backlight.

I hope this helps.

I have a dell 1525 laptop - I replaced the inverter, I replaced LCD the new LCD also had an inverter and I replaced the video card. I still get a faint dark screen. I can hear the music when Winn 7 boots...


Hello, and thanks for using FixYa.

What do you mean you replaced the video card? that is impossible, you would have had to replace the whole mainboard.


Okay you replaced the inverter, I suppose it was a tested and known good condition working inverter? does it work on another machine?

The lcd display, same with inverter? Has it been tested that its backlights work properly?

Then aslong as the small cable between mainboard and inverterboard is connected properly, it should work. But if it does not you have 3 possible causes.


1, Faulty display backlights
2, Faulty inverter board
3, bad cable / inserted wrong or motherboard is not providing the required electricity to the inverterboard.

Has a Toshiba Tecra 9000 won't power up. Power light on front is blanking which appears to be a code 3-3-2


The problem is cause due to one of the following: the backlight or the display, check your monitor brightness settings. Sometimes your brightness may accidentally have been all the way turned down, resulting in a blank/dark screen. The monitor controls are on the keyboard, directly above the numeric keys.
Look closely at your laptop's screen if the steps do not restore power to it and if it remains blank. Can you see a faint image on the screen? If so, the backlight may be off due to the LCD "lid close" detector malfunctioning. This malfunction likely happened due to the lid close switch being stuck in the "closed" position even though the lid is open. The switch is located beside the LCD's screen hinges, and tapping the switch a few times should unstick it.
Use an S-Video cable and plug your laptop up to an external monitor, such as your television set. With the laptop and TV hooked up, turn both on and see if your computer's desktop is displayed on the TV. You can also use a fifteen ( 15 )pin monitor desktop monitor by connecting it to the blue fifteen ( 15 ) connector at the side of the laptop if you cannot see anything on screen it is the display problem. If it is, your laptop's display needs to be replaced. If not, your motherboard and/or video subsystem may need to be completely removed and replaced.
