When i turn the monitor power button on monitor come on for about 3 seconds then screen goes black but power button is still lit. tryed old monitor and it works fine

This could be because of the 'eco' friendliness of the monitor. Basically a lot of monitors are designed to turn off into a low power state when not in use so to preserve power and life of the monitor. I would return the monitor as the sensors that control this seem to be broken in your monitor.

I have been to YOUTUBE to see video clips of cold cathode fluorescent lamp, back-lit, lcd monitors being repaired by their owners / technicians and have see some that are very good. Some are not so good with documentation. How "OLD" did you say unit is?? Will unit do same exact thing (black screen of death) when connected to different pc??? Research, Research, then come back to fixya for more info if you need it. Then read fixya profiles of "budmrtn" "buddymc" "12fixlouie"

• 1) TAKE OUT YOUR LAPTOP BATTERY
• 2) REMOVE YOUR AC ADAPTOR CORD, that's the wall power, remove it.
• 3) NOW HOLD DOWN THE POWER BUTTON FOR 30 SECONDS.

That will drain any static electricity that has built up on your laptop system board and many times fixes the problem of a black screen. After the 30 seconds re-connect your laptop to the wall power and hit the power button normally and see if the laptop comes back up.

Replace your battery.
Restart!

hi,

you can try to change the screen resolution with a spare monitor to a different setting, usually higher 1024X768, then unplug the old monitor and then plug in the flat screen. try different resolutions untill it submits. if you cant get it to run on your machine, take it to another computer and see if you can get it to run on that. if it wont run on either then you have a problem with the monitor. pawn shops usually have flatscreens for way cheaper than new..

Bad caps in the power supply, common problems. See examples here: http://s807.photobucket.com/albums/yy352/budm/Viewsonic%20V912B/

The problem is not with your screen. Its the problem of Video Card of your system which is unable to send Video Signals to the Screen.

it seems tht the monitor has gone bad & needs to be replaced....try running a monitor self test by unplugging the monitor cable frm the back of the cmputer & make sure the monitor is receving power frm the wall outlet....chk if the monitor displays anything......let me knw if it wrks

I have the same monitor and it is only 3 month's old, the power lock button continues to fail and they have replaced it 3 times with the same issue, What a piece of ****!!!!

How old is the computer? Make sure that the power light comes onto the monitor when you plug it in, should be orange and then turn green when video card syncs with it when PC is turned on. If you are getting black screen when PC is powered on:
1. Bad video card
2. Bad video cable
3. Bad monitor
1Solution: Try using a different monitor attached to this same PC and see if it works. If it does, then its the monitor, its cable, or its power supply. If it doesn't work, then its the video card or the video cable coming from monitor.

ok, get to the event where you get this to happen "...then turn it back on the monitor does come on normally...", but just after power-up, press the F8 key to go to safe mode. If nothing visible, press ENTER anyway...get to safe mode yet?
