When I turn on my computer the monitor turns on for about 3-5 seconds and then goes black. The blue light stays on and does not blink. If I turn the monitor off then back on it will again show the screen...


Had same problem, Monitor first turn on, backlight off after couple of minutes, off/on backlight off after few seconds.
Solution cut J503.
Found voltage OVPT (IC501,7) quite low (1.6V) this is the reference value for VSEN the over voltage value. By cutting J503, OVPT becomes 4.5 volt but is not depending anymore on the current through the lamps. Instead of the link J503 I solder 2x 1N4148 diodes which makes the OVPT not go below 2,8 volt. (diodes in series, cathode points to nearest board edge)

Monitor goes blank after 3 seconds -Samsung SyncMaster 920NW


Could be a power issue. If it doesn't show anything at all then that may be the case. It may also be the display itself. It would be a costly repair so you might be better off finding a new monitor.

Monitor turns off after about 3-5 seconds


I would say your monitor is bad if you have tried it on 2 different monitors and it does the same on both. Check your warranty expiration date, some monitors have 2 or 3 years warranty. If it's still under warranty, you may be able to have it replaced or repaired.

I have a HPw1907 monitor and it will turn on for about 2 seconds, and it turns off. The CPU is fine, just a problem with the monitor. Any way to fix this?


We have the same model of monitor and had the same problem few days ago. The monitor just goes black/turns off. I noticed that the power button has a yellow blinking light and cannot be turn on/off again using the power button. The CPU is working fine also. When I turn off the avr, the power button's light turns blue for a few second and you can hear a click sound from the back of the lcd before it totally turns off. My lcd monitor is over a year old now and is 110v or 220v capable. Mine was originally in a 220v, i just put it in 110v and the monitor was fixed.. Hope this can somehow fix your problem.

Screen comes up for about 10 seconds, then goes blank


Hello Robert,

You have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of he monitor. If you are good at electronics repair/soldering you can usually fix he problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts, replace any that look like the pictues and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping. I hope this helps, if so please rate my solution.

Sharp light turns green thern turns yellow screen goes black


it is going into sleep mode, good luck with this.... i am currently asking how to get my hard drive to quite putting my monitor into sleep mode.

although it hasn't worked for me because my screen stays black, one of the options given to me is to try to start in safe mode and then adjust your settings to "never" on the energy/sleep/hibernate mode

some one else suggested that i remove and reseat the video card

hopefully one of those will work for you

Problem with monitor


Hi.
Are you able to see a slight image on it at dusk and maybe with the help of a flashlight. since your blue light stays on the video board, may be okay.
It sounds like you have bad capacitors on your powerboard or possibly a burned out transistor on the inverter.

Only way to really tell is to open it up.
If you unplug the screen to video board ribbon, you may notice a different effect in the screen lighting.
There is a chance one of your bulbs is creating a problem
Should the screen happen to light up all white, then your power board and inverter are okay and the problem may be in the video board.
If it looks pinkish or dark or flickers then the bulbs or a bulb may be the issue.
If it flashes on then goes off, it's in the power or inverter board.

Problem solved! The main power thingy (the thing with the big red wire coming out of it) was all black and dusty. There was 'soot' all over the whole insides of the monitor. I concluded that this monitor should be laid to rest, and a new flat-screen monitor erected in its place.
