Question about Acer AL1715 17" LCD Monitor

Flashing green power on light with no display

I switched the screen off with the on/off switch as well as at the wall socket. When I switched it back on again I got the on/off green light flashing with no display. I rechecked all wires and everything is secure. If I hold the menu button the screen flashes and for a second i have a display. I have switched the screen of a couple of times as well as restarting my Pc but it is still the same. Everything was working fine prior to me switching the screen and pc off. I have not changed anything on my pc or the screen. I can not find any information on resetting the screen or any problem like this.

    The problem is not with the PC, but with the screen. The PC starts up normal but the screen is not functioning correct. Whether the pc is connected or not the screen green light flashes as soon as you connect the power cable. When the pc is connected to the screen and has started up normal there is no visual on screen just black with a flash every couple of seconds as the green light flashes. If you hold down the menu button on the screen you can see the windows screen everytime the green light flashes for a second. So the pc has no problem and the video signal is coming through to the screen, but for some or other reason the screen does not display it. Normaly the green light will stay on (not flashing) if no connection with pc it will bring up a message that reads no signal, and the green light will change to orange as the screen goes into standby mode. If you start the pc or connect it to the screen it will pick up the signal and the orange light will change to green and display. Now none of this is happening. As I said, the green light comes on and flashes and no display, except if I hold down the menu button I can see everytime it flashes that there is a display.

    things to check.



    1. i you have a external video card, remove it and scrub slightly the copper contact with a tissue in both sides until all clean.



    2. remove all RAM modules and do the same, clean contact in both side with a tissue.



    3. does the PC make a pause sound like one beep when it rebooting?



    let us know if it made some difference.

Why is the power light on my Acer monitor flashing?


See this.. http://www.techsupportforum.com/forums/f25/acer-monitor-is-blank-and-power-light-flashing-green-318760.html
Also, here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
Good luck.

My epson tx700 printer dispaly ink pad at end of life and printer not start


A fix from a forum:

Procedure 1 We found this procedure to work for the Stylus Photo 1270 type printer, and understand that it also works for the 870 range and even earlier models like the Stylus Color 740. The error is indicated on these printers by all four lights on the printer flashing. Even if you press the power switch on the printer, the lights continue to flash, and the printer does not turn off!
  1. Turn off your printer, ensuring that the print head is at it's home location and locked in place as normal;
  2. Power off the printer at the wall or by removing the power cable, for at least 20 seconds;
  3. When you restore power to the printer at the wall socket or by reinserting the cable, if the lights come back on straight away, the printer's power switch was 'on' - switch it off and return to step 1;
  4. Hold down the paper-feed button and the button with the ink-drops next to it, and then turn on the printer, still holding the buttons down;
  5. When the paper-out LED flashes, release the buttons;
  6. Press and hold the Cleaning button, until several lights flash - this will take a few seconds (i.e. then release the button);
  7. The printer will now attempt to reset, including resetting the EEPROM memory and running a short (about 10 seconds) cleaning cycle.
Procedure 2
  1. Turn off your printer, ensuring that the print head is at it's home location and locked in place as normal;
  2. Hold down the paper feed button only;
  3. Turn on the printer;
  4. As the paper feed light starts flashing, release the button;
  5. Immediately hold down the ink-drops button for some 10-20 seconds or until the printer springs into life;
  6. Allow printer to complete it's processing, then turn off for a few seconds, and back on again for a newly working printer!
Procedure 3 - for 1290 and possibly 890 printers 1290 printer with green (power / data) and red (ink / paper feed) lights flashing alternately:
  1. Switch off printer with panel switch;
  2. Switch off printer at mains switch - leave off for 20+ seconds;
  3. Hold down roll feed and sheet feed buttons;
  4. Switch on at mains;
  5. Switch on at printer panel;
  6. Continue to hold down roll and sheet feed buttons until both green and red lights flash together in synchronisation, not alternately;
  7. Switch printer off and then, after a few seconds, on again at mains switch;
  8. When red and green lights are both flashing in synchronisation, release the roll and sheet feed buttons;
  9. Press and hold down the ROLL FEED button (the one at the extreme left) and keep it down until the machine finishes whirring, cleaning etc and the green light comes on steady;
  10. Release the roll feed button and all should be well.

Hello

There is something confusing the system control of your TV and it should me resetted. To reset it, just switch OFF your TV with its front panel power control switch, and after that, unplug the TV from the wall socket. Wait for about 5 minutes or so, and the plug it and switch It ON. If this does not work for the first time, give some more time to reset, say about an hour or so, and try. OK.

Try resetting the video output. Follow the steps below:


  1. Before changing cables, make sure the PLAYSTATION 3 is turned off using the main power switch on the back of the PLAYSTATION 3 (the 0 side is pressed down).

  2. Unplug the power cord of the PLAYSTATION 3 and television (or display) from the wall socket.

  3. Make sure the AVI cable is connected to the [AVI OUT] port on the back of the PLAYSTATION 3 system.

  4. Connect the other end of the AVI cable into the [AVI Input] port of the TV or display monitor.

  5. Plug the PLAYSTATION 3 and television (or display) back in to the wall socket.

  6. Turn the main power switch on the back of the PLAYSTATION 3 back on (the line on the power button is now pressed).

  7. While the PLAYSTATION 3 system is in standby mode (red light on the front of the system), hold down the touch-sensitive On/Off button on the front of the system until the system goes into standby mode again . (So the light cycle would go from: red light to --> green light --> then back to red light) This will ensure that you have held down the On/Off button long enough to reset the Video Output Settings.

  8. Turn ON the PLAYSTATION 3 and once the system finishes powering up, the Video Output Settings will automatically reset to the standard resolution (or detect the current display output settings of your TV/monitor).

Sounds like a power supply problem. How many times does the light blink? The times that the light blinks could possibly tell you around what circuit is having a problem.
