Question about X2Gen MG19VT 19" LCD Monitor

1 Answer

Power turns off and on fr abour 5 minutes before finally staying

Monitor flashes on and off incontinuesly for about five minutes before the power finally stays on and then the monitor functions ok. This happen when the computer has just been turned on from the sleep or off mode. If not using the computer for 'X' amount of minutes and it goes into a sleep mode you can depress the space bar to reactivate it and the monitor powers up ok in that situation. What could be the problem?

    donco1937, Your lcd display may have problem if it only happens (on/off/on/off/on/off) during the initial first turn-on of the day when unit is same temperature as the room where unit is used. Unit may have developed one and one only "thermally-intermittant" solder connection of a passive or active electronic component to the copper trace to which it should be solidly attached!!! Once the unit is warmed-up to operating temperature (5min of on/off's) the printed circuit board will "warp" (contort) slightly and now the intermittant connection will become "closed" and unit will now operate consistantly. Turn off lcd display, let it cool back to room temperature (2-3 hrs) and same thing should happen. Try blowing warm air from hair dryer into unit's vent slots on rear side before turning on the unit to see if 5min of on/off's decreases to 1 or 2 min of on/off's when unit is in "cold state". DO NOT HOLD HAIR DRYER CLOSER THAN 12 INCHES FROM UNIT!!! Let us know results of testing. 12fixlouie

Hello,

This is a classic symptom of a failing power supply. After 2-3 years of use many LCD power supplies will start fail because of parts called capacitors that start dying due to the heat buildup in the monitor case. If you can solder then you should be able to do the repair yourself. Check out this page on our web site; http://www.ccl-la.com/blog/index.php/capacitors/ This article explains what capacitor are, how they fail and what you will need to get for the replacement parts. The parts can be ordered from many places on the internet, we stock they too. If you don't want to do the repair yourself we do offer a repair service, that info can be found here: http://www.ccl-la.com/blog/index.php/service-request-form/

I hope this helps you, if so please rate our solution.

Viewsonic VX2640W was running with the screensaver on,then suddenly went solid white. Turned off for thirty minutes then back on with same result. Unplugged from computer and turned on. Still turn


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 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.

For the past week, when my Sceptre LCD monitor goes to sleep after inactivity, it won't restart immediately. The blue LED blinks every second or so; eventually, the screen begins to flash the display, and...


Hello there Jake.

Here's your geek-steer ...

== CLARIFICATION ==
  • When you say "sleep", are you certain it's sleep mode, as opposed to hibernate?
  • "...it won't restart immediately." ... you do mean of course AFTER you've given keyboard or mouse input, right?
  • "...the screen begins to flash the display" ... literally flash, as in strobe? Or do you just mean flash, as in "shows".
  • "...Sometimes the whole process takes five minutes, sometimes an hour." ... ???!!! If it takes anything longer than few/several moments, that's very abnormal, even if hibernate mode.
  • "...I can't find the documentation." ... not important, at least not at this point.
== SUGGESTIONS ==

A. RULE OUT THE SIMPLE FIRST.

1. Shutdown
2. Turn off PC and monitor
3. wait 5 minutes
4. unplug all cables/cords connected to monitor (both ends)
5. inspect/clean connect points
6. reconnect all cables/cords
7. plug monitor back in
8. startup system
9. try to duplicate problem

B. CPU HOG.

I'm curious to know what all your "Processes" are doing during this very delayed period of time. By knowing that, you can see which one(s) are running, and which of them are probably crunching hard at the CPU, which MAY explain the delay (I don't know about an hour, but minutes ... yes).

Do you have a "Processes" monitor utility of any kind? If not, get SysInternals' "Process Explorer" (no installation required, just unpack and launch). Make sure at least the "CPU History" item is included in the column header (View > Select Columns). Once launched, allow it to sleep.

Just as soon as able, after it comes out of sleep, review Process Explorer. What, if any, processes are hogging CPU? Post that back, and I suspect we may be a lot closer to a solution.

C. MONITOR FAILURE.

You might also hook up this monitor to a "known good" (functioning properly) PC with like "screen saver" and "power options" settings. If problem not encountered, you can at least isolate the problem to solely the monitor. However, if the only time you encounter problem with monitor is isolated to when coming out of sleep, this is likely a long-shot.

Good luck Jake, and please do post back ...
  • to let me (and interested others) know how things worked out,
  • to provide clarification or feedback.
  • if you have any further questions,

Blank screen after monitor sleep just blue flashing light


Hi,

First of all you can change the Power Settings in Control Panel. You can configure as you need. I mean after how much wait it should go for sleep n all.

If it takes 5 min. to wakeup that means you have so many applications running that system cannot manage or RAM is small.

The final solution just remove the Display drivers and reinstall it.

After removing please restart the system once to proceed further

Power light flashes but monitor wont turn on


Your monitor is not receiving a signal from the computer.

First try the monitor on another computer and/or try a different monitor on this computer. If the monitor continues to have a problem, then either replace it or have it repaired. If a different monitor does not have the same problem when hooked up to this computer, then once again the monitor is bad.

If a different monitor has the same problem, then try the next few steps.

Turn off your computer, wait 5 minutes. Then remove your video card. Wait 5 more minutes (video cards take longer to drain residual charges than most other components) and then install the video card again.

Try borrowing another working video card and connect it to your sstem after removiing the current one. If you can see the text during the boot process when you turn on your computer, then your video card is bad and needs to be replaced.

If none of the above steps works, you may have a problem with a different component in your system. While off and unplugged, disconnect all expansion cards (RAM memory too) and drives with the exception of your video card and then attempt to boot your computer. if you are able to see the tex during the boot process, then some other component is bad; replace them one at a time after shutting down and unplugging your system until the problem comes back. That will be your bad part that needs to be replaced.

Strange delay.


I'm having the exact same strange delay problem as you.
I fixed my delay when I too took my machine to your girlfriends. LOL!

No seriously.... you solved your delay problem yourself when you UNPLUGGED the power cord from the back of the monitor.

My guess is that when you unplug the power cord, the monitor resets itself. It's only a temporary fix, but, IT WORKS.

1. Turn the monitor OFF
2. Unplug the power cord from the back of the monitor
3. Wait 10-15 seconds or so
4. Plug the power cord back in
5. Turn your monitor ON........DELAY ELIMINATED.

The delay returns eventually, but, I just unplug-n-replug and I'm good to go again.
