Did the same and burnt a frazzled chip. it is on the 3rd circuit board (I believe it provides the lamp power). It is the 8 pin surface mount chip next to C900. As far as I can make out, the numbers on the chip are 4559 **** **7B I was told it's the lamp drive. If it is indeed lamp drive, then when you turn the monitor on, round the edges of a flashlight pressed to the screen, you should see a picture. If there isn't one, you may have killed more than I did. Is there no power regulator at the input? Good luck

My monitor no display and light is blinking

Hi,
if the monitor light is blinking this suggests that, there is no display signal coming from the tower. This could be because of the following .

1. Bad video card 2. Bad video software

To check,where the problem is , power of the system tower and remove the power cord from the back of the tower. Press and hold the power buttoon for 10 seconds and the reconnect the power cord and turn the tower on. Check if there is any display or the status of the light changes from amber to green for even a small instance.

If the light changes to green and back to amber the video port on the tower is bad

Alternatively you can connect the monitor to another desktop or laptop to check if the same is working correctly.

Thanks for using fixya

No sign of life from the display half but the bottom reads life.

Hi,

If you have already checked the connections from the screen to the PC, check that you have a power light on the screen. (Green or Amber). If no light, check power to screen. If it is amber, then the screen is not getting a signal from the PC - recheck connections. I would suggest you try and connect the pc to a different monitor to check whether it is the screen or the PC.

If it is the same on another Monitor or if the power button is green on the screen, then the pc is not sending information properly. Turn the pc off manually by holding the power button on the bottom half for about 10 seconds. All lights should go off from it. Now turn it back on again and see what happens.

If you see loading windows and then goes black, do the following:

Turn off the pc (bottom half). Turn back on and as soon as you pressed the button to turn on, start tapping the F8 key until you come to "Windows Advanced options" screen. use the arrow keys and go to Enable VGA mode. Press the return key twice. If it loads to windows, then fine. If not, then you may have a problem with the display adapter.

Hope that helps

I have an Acer AL1912 that when you plug in the ac, the green power light will blink for about a minute and a half then go solid. The backlight will come on and you can see a faint ghost of vertical lines...

If it is still in warranty call the manufacturer.
if not give more info [email protected]. May be somthing simple like a cable
shutdown computer unplug then disconnect the video cable on the computer from the monitor, plug monitor back in and turn it on, there should be a display that says no video source within a few seconds, if unit is working properly. shutdown and connect video again and then reboot computer. sometimes it just takes a compleat power disconect to reset things,

Dell dimension 5150 blinking amber lights

I have similar problem these days. After normal shutting down the PC, it can not be powered up again, the amber light blinks. A temp solution for my case is by doing these steps:

1. leave all monitor, network, keyboard and mouse etc. connected
2. disconnect the power, wait until green light and amber light dim.
3. pop up the CMOS battery, then put back in (better to check its remaining voltage, if not good, change a new one)
4. power amber light flash shorter and lighter
5. disconnect any USB connections like keyboard and mouse,
6. immediately connect keyboard and mouse back into USB ports
7. my pc powers up at this point, all green lights shining. Except it displays CMOS setup warnings, give me options to click either F1 or F2
8. I click F1, it goes into normal login XP

The only problem is I could not shutdown PC again, if I do, then I have to repeat 1-8. I have to use "Standby" instead, which I usually do.

Lcd monitor power light flashing with no img. seems 2 be frozen

The display is in safe mode and you will need to reset the display to get the display out of the safe mode. There are 2 different model revisions. Please choose the method that will match your revision. Depending on the revision of the monitor, one of the following 2 methods should reset it to a normal state. This reset generally requires both hands and it is sometimes easier with another person.

If the serial number begins with an A and/or your power button on the far right (5th button from left):
Method #1
1. Unplug the VGA cable.
2. Remove the power cable from the back of the monitor.
3. Counting the buttons on the front of the panel from left to right as 1 – 5, hold the buttons 2 and 3 down at the same time (see picture above) and while continuing to hold the buttons, plug the power cable back in.
4. Keep holding the buttons for 5 seconds after the power has been plugged in and then let go. The green light should be steady when you release the buttons.
5. If the procedure worked, the green light will go to amber and you should see a "No Signal" message on the screen for a few seconds.
Method #2
1. Unplug the VGA cable.
2. Remove the power cable from the back of the monitor.
3. Counting the buttons on the front of the panel from left to right as 1 – 5, hold the buttons 2 and 3 down at the same time (see picture above) and while continuing to hold the buttons, plug the power cable back in.
4. Keep holding the buttons until the 4th green LED blink; then, let go. The green light should be steady when you release the buttons.
5. If the procedure worked, the green light will go to amber and you should see a "No Signal" message on the screen for a few seconds.


If the serial number begins with a B and/or your power button is in the middle (3rd button from left):
Method #1
1. Unplug the VGA cable.
2. Remove the power cable from the back of the monitor.
3. Counting the buttons on the front of the panel from left to right as 1 – 5, hold the buttons 2 and 4 down at the same time (see attached picture) and while continuing to hold the buttons, plug the power cable back in.4. Keep holding the buttons for 5 seconds after the power has been plugged in and then let go. The green light should be steady when you release the buttons.
5. If the procedure worked, the green light will go to amber and you should see a "No Signal" message on the screen for a few seconds.

Method #2
1. Unplug the VGA cable.
2. Remove the power cable from the back of the monitor.
3. Counting the buttons on the front of the panel from left to right as 1 – 5, hold the buttons 2 and 4 down at the same time (see picture above) and while continuing to hold the buttons, plug the power cable back in.
4. Keep holding the buttons until the 4th green LED blink; then, let go. The green light should be steady when you release the buttons.
5. If the procedure worked, the green light will go to amber and you should see a "No Signal" message on the screen for a few seconds.

If you have tried the reset a few times and it does not solve your issue, please Ask a Question to submit a request through the system or call 1-866-752-6271 Option 1 to contact technical support.

Soyo 19" flat screen monitor

Hi, these monitors are dropping like flys and it's due to power supply problems. There is a power supply that needs to supply 5v, 12v, 24v. The 5v and 12v is for the logic boards and the 24v is for the back light. On other boards people have tried to repair the supplies with no luck (same here).
The best fix is to purchase two power bricks off of ebay. Get one that supply 5v 12v that are used for external hard drive enclosures and get one 24v that is used for mac g4 laptops. Both can be had for < $10. Then you will have to replace the internal power supply with these. This is not for the beginner, but if you have any experience with soldering and wiring you should be able to do it. You will have to tap into the 12,5 volt wires, I used the PC style power 4 pin connections and attached the other end to the power supply. You will also have to do this for the 24 v lines. A bit of cutting / stripping, soldering and getting the AC to both will do the job.
The only thing that this will not do is shut of the 24 v supply during idle. Best this is to remove power from the monitor when not in use. This should fix an no / power / on then off / problems with this monitor.
Total time is probably about 2 hours and tools needed are the replacement power bricks, cutters, soldering iron, solder, electrical tape, screw driver... etc

No display (black) - power light is amber color

The video signal is not reaching your monitor, check the pins on the connector from the monitor to the computer, then check the video card:

Turn off your computer, unplg the power, and then take out the video card. Wait 5 minutes and then put the card back into the computer and turn it on. For onboard video; turn off the computer, unplug the power, then hold down the power button on the front for 5-10 seconds, then plug back in and turn on.

Make sure the video card is snug in the AGP/PCI slot. If this is built-in video, try borrowing a video card from another computer and install it in this one. If the borrowed card works, then replace you card. If video is built in, then you can disble the onboard video and use the new card without having to replace your motherboard.

Monitor doesnt come on , but the power light goes from amber to green. then comes on after 20-30mins maybe.

Maybe update your display drivers. PC appears to be slow.
Make sure you don't have a bunch of apps that auto start.
Do you hibenate your PC?
Same issue if you connect monitor to another PC?
If issue follows you to a different PC it says monitor. If it doesn't it says the first PC (that monitor is currently connected to) had a cpu/memory or a driver issue.

Good luck
