Power on problem when cold

When my computer has been off for over a period of a few hours on startup my monitor flashes on for a second or so then goes black with the green light on. it does this for the xp startup logo and the welcome screen then remains black. successive reboots and/or turning the monitor off and on for a period of 5 to 10 minutes and it then works perfectly. it seems it has to warm up to turn off and on properly. does anyone have any idea what could cause this

Monitor turns off after a few seconds. Have to


my_secret_mb, Stop pressing the ON/OFF switch! It's broke!!! The unit's internal power supply will need some work done on it. Unit will need to be evaluated first!! This is a common problem for ALL LCD monitors. If unit out of warranty period, then you will need to do some intense speed reading of my higher page number responses in my fixya profile to understand the problem your cold-cathode-fluorescent-lamp back-lit lcd monitor has and the options that you have. You will also need to base your decision on the age and total number of "ON" hours unit has seen during it's lifetime. Do not dispair or feel sad about what has happened to your monitor. A low side guess would be 50 units/day fail world-wide. Your unit may have failed filter capacitors or possible failed solder joint on printed circuit board. (thermally intermittant) I hope this helps you. 12fixlouie north of "Windy City" USA

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,

Viewsonic VX724 monitor flashes on/off every few seconds.


Check for puffy capacitors, they will be bulging instead of having a flat top like most good ones do. If you see any puffy capacitors, be sure to replace them with capacitors with the same UF rating, voltage of the capacitor can be the same or higher.

If you don't see any puffy caps then it could be the screen itself that is bad. If thats the case then the monitor itself is bad.

Samsung monitor picture clicks off after 2-5 seconds...


Yes, It sounds like the backlight inverter circuit is shutting down. No inverter power, no backlight. On some monitors the inverter circuit will shot circuit the power power supply which makes the power light flash on some it just kills the backlight. You can usually check with a flashlight. Hold the flashlight pointed at the screen and see if you can see any of the icons or background picture. If you can then it is the backlight circuit or backlight tubes, usually the circuit.

Lg flatron w2234s monitor is flashing ??


I am going to suggest if it's only 3 months old you should take it back to where you bought it. Mine quit working right a few weeks after I bought it and they gave me a new one. Be sure you take your receipt with you. Even new things can mess up.

Monitor flashes on and off!


Sounds like you have a bad connection from your monitor to your computer. First check and make sure the connection between them is tight. Does your computer boot up and run though? If your computer is not booting up the monitor will default back to the flashing green power light
