Screen does not light up

When I power up, the screen does not light up but if I aim a flash light at it, I can see that it is on. Is my screen done or is there something I can do?

Sounds like you need to replace your backlight lamp, or inverter.
If you need help with that, let me know

    You'll have to be adventuresome enough to tear into the top cover of the unit. The biggest issues are to find all of the screws that need to be removed, and then removing the bezel that covers the edges of the LCD.
    The service manual does not show you how to do it, and I've not personally done this on this particular model. So, I'll give you a generic "How to".
    1-Find all of the screws that need to be removed. This can range from 2-10 in number. Sometimes the screws are hidden under small flat pieces of plastic self adhesive covers, or under rubber plugs that need to be removed.
    2-Remove the screws and KEEP TRACK of which screw goes back in which hole!
    3-After you have the screws out, you will need to remove the bezel. Usually this is just snapped in place and you will need to work it loose.
    4-Once the bezel is off, you should have ready access to the LCD assembly. You should see the inverter (small circuit board with a connector on each end). That's easily replaced and a new one will range from $10-$65, depending on which one you need.
    The back light is easily accessible on some LCD units, and real hard (to impossible) to get to on others. The LCD lamp is usually pretty cheap. Ranges from $5-$10.

    Being your first time doing this, it'll probably take a couple of hours, or less.

    If you are of the mind to do this, let me know and I can try to walk you through any areas that you might have trouble with.

Hp touchsmart 520 when i press the power button the blue light come on sound like it turning on but a blank black screen done this from new


Let it power on. If it plays the normal windows music then look very carefully at the screen. You may need a flash light. If you see a faint image then your inverter board or back light have burnt out. It will a small board 1 x 2 inches usually and have a small wire coming from the power supply and one going to the bottom or top of the screen.

The light on the front of my soyo monitor is flashing and it wont turn on no matter what i do got any ideas? is it just done for?


The flashing light indicates there is no video signal reaching the screen. Check the cable between the screen and computer. You can even turn it around and use the other end in the screen. It should be the same at both ends. If still nothing turn the pc off and on again.

MAG innovision LT-926W 900W problem! After I turn on my computer, the screen immediately begins to flash and then goes black. The power is still on thought and so is my computer. If I take a flash light...


this means your power inverter inside the monitor is dead. This little gizmo lights up the monitor backlight. They dont fail all at once, but slowly die and give problems like you describe, you can order these online for your monitor , or find one on ebay for under 30 dollars, but unfortunately there is no fix, other than replacing the inverter. sorry. Please use the thumbs up rating if you find my answer helpful, albeit bad news. Take care. .

Blue flashing power light only


kdavey53, "switch-mode-power-supply" for X193W is probably in shutdown mode due to having detected a FAULT CONDITION with itself or another circuit. Black screen = partial shutdown?? Black and Blank screen = full shutdown??? Which is it? Are you going to repair unit or use warranty? Have you seen video clips at youtube for "LCD monitor disassembly" and "LCD monitor repair" dealing with the most common black screen problem with ALL BRANDS of lcd displays? FYI visit www.ccl-la.com/badcaps.htm or www.badcaps.net or try wikipedia and search "capacitor plague" !!! Read more of my responses to other BLACK/BLANK screen owners for more options that you may have open to you. If not inclined to DIY repair, then have deep pocket$$! Your best shot and what I would do is buy new AND repair X193W to keep as working spare unit. Might only cost $10 in parts on a DIY. But you will need to do the research and understand the problem that you monitor is having. Do you understand what makes your screen "light-up"? Have you any of the new style "curlie-Q screw-in energy saving CFL light bulbs? Same basic principle! Just implemented in different way to produce RAW WHITE LIGHTon reverse side of what you been looking at. Look see only FYI www.ccfldirect.com and then you will know. I'm lmistyrel on aim or 12fixlouie on fixya Hope this was of some use.

Ds lite flashes on but fuses are ok


One or both your screens have blown.

Try removing the motherboard from the screens and attach the battery the green light should turn on and stay on.

Now attach the lower screen and turn on. If the screen is ok the screen and green light will flash and then turn off. (if the screen doesn't flash the bottom screen is you're problem and will have to be replaced)

If this happens the problem is then you're top screen which you will have to replace.

Screen flashing


What I have done in the past is to change to project to high power mode for some time and then change it back to low power mode after 20-30 mins. This fixes the flashing light issue, at least temporarily.
