Screen on Gateway FPD2185 stays black.

Screen is black. "VGA Input" flashes on screen momentarily when fired up. Power light stays'ON'. Display can be seen faintly with a flashlight shone on screen. Voltages to logic board look good. Electrolytic caps have already been replaced. Polarities are correct-I did it myself.

The back light is out. Might be the inverter or the tube.

Testimonial: "This is a non-answer. Of course it is either the inverter or the backlight. "Might be" is never a solution."

    Ok, unless you have a high frequency VOM or oscilloscope, then you would not be able to test the inverter so a shop has an advantage for that reason or they can swap inverters to see if it is that or the tube, it is a process of elimination on their part. The only sign that it might be the back light tube is if the display was tinted orange before it went dark. It is cheaper to get the inverter than it would be the back light tubes.

I would check the caps with ohm meter. Make sure they all show increasing resistance. Caps can be bad without looking bad. Check output voltage on the power board, should be around 12V. If all that checks out then I'd look next at the backlight bulb. I'v repaired many monitors and the problem was almost always overheated caps on the power board. Post back and let me know.

Try different video and/or power cables, but most likely this is dead. Sorry!
If it's still under warranty, (or the computer it came with is), call Gateway support.

SOURCE: My Samsung SyncMaster T220 does not display

m_r_murphy, The T220 may have developed an internal ac to dc "switch-mode-power-supply / CCFL inverter supply" power problem an you may need to need to have it repaired, Look into warranty or outside technician to refurbish the unit's SMPS/inverter!!! From your description, I believe that the SMPS is in "partial shutdown" mode!!! (no 12 to 14v dc) to power-up the "cold-cathode-fluorescent-lamps" that enable you to see the text and graphics that you already know are being displayed on your lcd panel!!! (+5vdc or 3.3vdc rail still alive!!!) You have "black screen" symptom!!! NOT BLANK n BLACK screen!!! There are lots of DIY videos on YOUTUBE to help you decide if you can attempt a cheap (<$20usd) repair to your unit. Do some reading in my old fixya profile (louie12fix) and visit some of the links you find there. Because your T220 isn't any different than any other brand of CCFL back-lit lcd display in it's basic design and operation you should be able to fix it. Get back to me lmistyrel on aim or do additional comment to this original post here on fixya with info on your next step to repair this unit.
All the other ccfl back-lit lcd monitor tech's on fixya already know what's wrong inside your unit!! Do your research first!! Bye for now, 12fixlouie

Sounds like the problem could be in the power supply of the TV. Have a technican check for defective capacitors if you're not equipped to do the job yourself.

Make sure the vga cable is in tight on the kav-60 and the external monitor.

Try the keystrokes to toggle the display. Normally you would Press and Hold the FN function key located at the lower left on the keyboard then hit the key F1 thru F12 that toggles the display. The correct F1 thru F12 key to hit will have LCD/CRT on it or it will have the icon of a display. The display toggles in three stages ( laptop only, external only or both laptop and external).

Gateway 5150 - computer screen stays black, screen works fine, just very very dark - can't seem to adjust luminosity?


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.

Your screen may have gone out - try hooking up an external monitor with a VGA input. Connect it to the VGA output of the laptop. If you get a display, your screen inverter or backlight has gone out. If the hard drive light on the control panel is flashing then the harddrive is likely ok.

I turned on my m-675 yesterday and got the gateway green and black screen that just continued to stay there. After 5 minutes I used the control/alt/delete buttons to reboot my computer. Now, my computer...


From the information, that you used control/alt/delete to re-boot, I am assuming that you sensed that the computer finished the booting process. Meaning the tell tale sound (music) of windows booting was there, the hard disk whirling (blinking LED) for a certain period and stopping etc. If that is the case, (meaning you think your computer is capable of booting) probably you have a display failure. If you have a VGA cable connect that cable to the VGA connector (0n your laptop) and connect the other end to Desktop screen (monitor) or a TV screen with a VGA input. Probably you will see a display right away. If not press the Fn key and the key which changes the screen from laptop to external screen. This key will be marked either as CRT/LCD or with a picture( a square with two lines on either side of the square). If you get a display there, you may need to get a technician to change the screen.

Screen only stays on for 1 sec


Assuming you changed all the caps and did it correctly.
IF you get flickering, It could be a transistor on the inverter board.
OR !!! and probably more likely,
It could be one of the bulbs in the lcd itself is failing. It only takes one bad bulb to stop an inverter from firing up !! You can check them one at a time if you have another working monitor.
If you do unplug a good bulb from the good monitor and try each of the questionable ones, one at a time.
Doesn't have to be a gateway monitor to test it, just needs the same backlight plug.
