The monitor should be plug and play, and you've already figured out that it's not your computer by plugging into a working monitor.

This is most likely the power inverter board in the monitor - this is common in many monitors. If the power light is blinking on-and-off, or just staying on with no image, that's the problem. There is a slight chance that it could be the light itself, but inverters fail more commonly.

If it's under warranty, send it back, if not, there are inverter boards for many common models of LCD monitors that are replaceable. The board can run anywhere from $50 on up. Depending on how old it is, you may find it better to just replace it with a gently used one from ebay.

SOURCE: do lcd monitors over heat and shut off screen

It is possible that your the lcd inverter board is failing or possibly the back light, i suggest taking the back cover off the monitor and checking the power board for leaking or slightly buldged capacitors, to spot this youll have a dark liquid traces on the cap or on the board, the top of the cap must be flat not bulged, if there are any they'll need to be replaced, you can get them from electronic stores like Maplins, and if you are able to use a soldering iron desolder the the ones of the board and solder the new ones on. Make sure you get the exact farad rating of the caps, it dosent matter to much about voltage as long as it is equal or above the voltage stated on the cap. Also insure that they are replaced the correct way around, check this before desoldering from board.

SOURCE: Monitor blacks out

You should try it without the KVM switch first.
Common problem in this monitor is poor soldering works on the back light assembly, try tapping on the frame when it goes dark. It can also be some where else also.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for:

It can be as simple as bad caps, or worst case will be bad lamp assembly.

Or just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

This is the strangest thing I've ever seen. I have a Gateway FPD1975W TFT Monitor and its always worked great. The other day it went into a sleep mode via windows, and now it wont boot up the input...


Your monitor problem is causes by the power supply. What is happening is the power supply voltages are not stable, just enough to power the unit up. When you connect it to a video signal the power demands slightly increase and the power supply can't handle it. This is a very common problem with LCD after a few years of use. The issue with the power supply is the capacitors have started to fail. These parts are used to filter the output voltage and when they start to fail the outputs start rippling hence the problem you are having. Here is a link to a repair article that shows how to repair the Gateway FPD1975W monitor.

I hope this helps you get back going.

First make sure that all the cords are connected properly from the back of the CPU to your Monitor.I suggest you to unplug all the cords of the CPU and then plug them back in after 10min. and make sure they are all connected tightly.Next check if the power cord connected to the Monitor is attached tightly.

If you still face the problem then you will have to replace it with a new power cord whih connects the CPU to your Monitor.It is black in colour.

My monitor does not turn on and the power button light keeps blinking

elvisy71, If different monitor will display the Win-desktop screen with no problem, then Gateway 2275w will need you or qualified electronics technician to possibly repair a defective internal "switch-mode-power-supply" / CCFL inverter supply" !! Check the status of unit warranty first, and check to see if Gateway has a swap-out (exchange+cash) program. If that dosen't work you will be doing a lot of reading about DIY lcd monitor fixes. You will also need to view some DIY video clips at YOUTUBE on "lcd monitor disassembly" and "lcd monitor repair" that will help you decide what to do about your now BLACK or BLANK n BLACK screen unit. You can find tons of DIY stuff here on fixya in my and other CCFL back-lit lcd monitor tech's fixya profiles. Elvis, remember this! Your 2275w isn't any different than any other brand of ccfl back-lit lcd display in it's basic design and operation and some can be DIY repaired for under $6 in parts cost. Just do some reading of the higher numbered (>16) pages in my fixya profile and my old profile "louie12fix" and follow the web links you find there. If this was of some help to you please come back to fixya and rate this response and tell me and all the other black screen lcd owners what you are planning to do about your monitor. 12fixlouie 42610

I have a gateway FPD2485W tft lcd monitor and i start my monitor and after it shows gateway it then goes black. How can this be fixed

bonannorl, Maybe it can be fixed. You did not give any history of unit. Only "now" stuff. Is unit covered by Gateway warranty? How old is unit? Date of manufacture? Did unit work fine connected to your pc and this black or black n blank screen thing suddenly happen? Is screen also BLANK? Have you swapped-in old monitor to prove PC is OK? Your CCFL back-lit lcd monitor no different than any other brand in it's basic design and operation. Get into my fixya profile and read some of my testimonials and solutions to black or black n blank screen problems to help in your decision to DIY fix or contract out needed repair work. Most likely 2485w has problem with it's internal "switch-mode-power-supply"/"ccfl inverter supply"!! Let me know more info about unit.

Gateway 900G does not stay on, has power

the_princes, On the rear side of LCD screen that you look at are two each long, straight, cold-cathode-fluorescent-tubes that need to "LIGHT-UP"and provide pure WHITE light to be reflected through the LCD glass panel that you look at from the front side! If you don't have any luck with Gateway providing warranty service or doing a swapout with them, then you should possibly look into having it Refurbished by someone locally in your area. I highly recommend that you go to youtube and watch some video clips of LCD MONITOR REPAIR to see exactly what you are getting involved with. When making a post to tthis site you should always give some "history" along with the trouble "symptom" such as how old is unit and approximate total amount of "ON" time the unit has. I hope you can use the info provided. I'm louie12fix on fixya or Bye for now.

My monitor light comes on but there is no signal.

Isolate the problem. Connect the problem monitor into different computer. If the problem monitor worked on another computer, try connecting a CRT monitor to the problem computer. Once the display comes back, change the screen resolution.

Gateway monitor FPD1975W won't display

Same problem - unplug both computer and monitor - hold power button for monitor for 15-30 seconds...then power it back on and then power on the computer. Seems from other sites there is a power issue with the monitor - this worked for me.

Screen goes black and power light goes out after a few minutes

it would seem that one of the internal components has failed / overheated Dont open the rear of the monitor !

if pos drop it into your nearest pc repair shop and have is serviced it may just need cleaned to free it from dust build up
on the inner parts this may be causing the unit to over heat
