Question about Gateway FPD2275W LCD Monitor

1 Answer

Monitor loses power randomly.

It starts working again when I push the power cord back into monitor. Tried a new power cord and the problem persists. Could it be the monitor is just giving a tight grip to the power cord anymore? My 20 inch Dell UltraSharp monitor randomly looses
power and the screen goes black. All the lights stay on
green. By pressing the off/on button to OFF, them pressing it to ON, the monitor comes back on and works fine. It doesn't matter how long I leave the monitor off.
It worked for two weeks without a problem. Now it is going off about every few minutes.

Is your monitor a CRT or LCD type. For CRT type information follows. In most cases your simptoms indicate a problem with the High Voltage or blanking circuits. Caution the High voltage can be as much as 40,000 volts and even unplugged from the wall the picture tube can continue to hold voltage (enough to hurt you). Do you here a snapping sound from the back of the crt. If you do the high voltage is shorting out and the protection circuit is turning off the high voltage. If you do not here sparking another possible cause is a faulty capacitor in the protection circuit or the flyback (high voltage transformer). Unless you are educated in electronic circuit repair this one is probable beyond your curren knowledge level. You can try taking the back off and cleaning out all the dust, but remember to stay away from the red wire that goes to the picture tube. Use only non metal cleaning tools. Good Luck

Gateway 19inch wide screen, lcd monitor stopped working randomly.


It could be a faulty power cord. Try plugging it in and moving the cord around in the areas where it takes the most movement. Do the same with the data cable to see if you get a response there. If your cables are fine, the problem is most likely hardware in the monitor - in that case you're better off replacing the monitor.

Monitor goes black


Sorry to have to tell you this, but this is common in LCD monitors. The reason that it is going black when it boots is for one of two reasons. You either have a bad power supply that powers your LCD or your LCD's backlight is blown. These can be repaired or you can purchase a new one. But if it goes black 9 times out of 10 is because the backlight is bad. These can be repaired!

Screen goes blank


Screen going black would indicate a data flow problem- but then you would see a warning saying words to this affect or a back light/inverter problem. If by looking slightly sideways at the sreen you can see 'shadow images'[try a moving image to be syre] then you have a backlight /inverter problem If you see nothing at all ckecj the data cable pins- one or more may be bent

Nothing on the screen after power on


Turn on the computer and complete the following steps: Step 1: Check cable connections (If you can see the initial HP or Compaq logo screen but later lose the picture, you can skip to Step 2.) check the video cable connection on the back of the computer and on the monitor. Make sure that it is connected properly and the connecting screws are tight. Turn the monitor off and then back on again (while the computer is on) to see if an image appears. Some Flat Panel monitors have two similar power input connections placed side-by-side on the back of the monitor, which sometimes allows them to get confused for one another. One connector is used to supply power to the speakers with a separate power cord, while the other connector is used for the monitor's power adapter. Ensure that you have the monitor's power adapter cord plugged into the power connector and not the speaker connector. After you have reconnected the power cord, turn on the monitor (while the computer is on) to see if an image appears. If there is still no image, continue to the next Step. Step 2: Resetting the monitor At first setup, or under certain signal conditions, the monitor may not be able to switch to a new display resolution. Do NOT shut down or restart the computer. Instead, perform the following steps: Turn off the monitor using the Power button on the front. If the Power button does not respond, unplug the power cord from the back of monitor and wait five seconds. Plug the power cord back in. You should see the image from the computer on the screen.
