Though itz very unclear n i don't understand the moral meaning of windows going down..!!..n wat is the link of windows going down with ur monitor..

however, itz probably causing from faulty or defective smps or main/mother board..
if not probably itz causing from the monitor itself..

proceed to verify with the below stated steps, only if u r a professional..

DO IT ONLY IF U R A PROFESSIONAL..
..plz do check the following as in order:..
the Hardware part:..
1) check mains/power supply..the fuse, switch, wiring n associated circuitry..

2) [in case of desktop] thesmps itself may b defective/faulty..check the outputs of smps viz. 0v(black~ground); +12v(yellow); +5v (red, green~ps-on, violet~pg&grey~sb); -12v (blue);-5v(white); +3.3v(orange)..
check the battery n adapter [main power], in case of laptops..
replace with a standby n see..

3) unplug mains supply..pick open/remove the cmos battery..check (above +3v)..resit..

4) open the cpu n see if heat is generated..if not..replace the cpu n see..

5) open the CPU Heat-Sink with fan out of thesocket..put some "Heat Sink Compound" (available in local electronicschip level spare market)between the cpu/processor and the CPU Heat Sink*** fan..resit/fit it tightly in position..

6) on main/motherboard..see with a debug card for mb error..may b short..look fordefective capacitors(espabove1000mfd)/mosfets..go through the mb'ssouth bridge n the circuit lie around atx connector..the crystal clockgenerator (if cpu isn't heating up)..
replace with a standby n see..

7)seeif the ram(s) is loose/faulty..open clean/remove carbon & or oxideformed on the teeth with an eraser n resit it..or replace with a standbyn see..

8)remove/clean dustneatly..dust is non-uniform in nature n may causejam/short circuitry/excess resistance n many more..resulting an increasein heat..

9) if all above fails..just try to service the monitor..open and re-sould all the dry soulderings..itz probably is causing due to ur monitor's internal circuit dry-soulds..esp. at the crt base n around the horizontal output section (hot)..

the Software part:..
1)hv a licensed and UPDATEDantivirus installed (i prefer avg/kaspersky,remember, without updationa full version antivirus is useless)..

2) download, install n run microsoft kb890830..http://www.microsoft.com/downloads/details.aspx?FamilyId=AD724AE0-E72D-4F54-9AB3-75B8EB148356&displaylang=en..

3) download n run Startup Control Panel..http://download.cnet.com/Startup-Control-Panel/3000-2094_4-10039330.html..'removeall the unnecessary startup items from here..(if u can't find whatto remove, post me/us in ur comment with all the items listed in eachn every tabs herein)..

4) remove all unnecessary software from add/remove programs..

5) download, install n run 'Advanced System Care Pro'..http://download.cnet.com/Advanced-SystemCare-Pro/3000-2086_4-10399324.html..

6)disable the following:..
a)'Automatically Restart'right click on my computer->properties->advanced->startupn recovery->(un check on the) Automatically Restart;
b)'Error Reporting'right click onmy computer->properties->advanced->error reporting->disableerror reporting->(uncheck on the) 'but notify me when critical erroroccur'..

7) Increase the size of Virtual Memory, Initial: 1440; Maximum: 2880

if u r not a professional, always better to seek advise from ur system admin/vendor....

Aadab: when the moniter ON after few second the moniter is does not give display and when we on and off the moniter so then the picture displayed why this problem is occure.how i recover it.


That is because the settings on the power are set for the monitor to go to sleep if not in use.. It is a very quick and easy fix.. Just right click anywhere on the desktop that doesn't have any icons, the display properties box will appear, then click on screen saver under monitor power click on power, there you could set the monitor never to turn off... Let me know if this solved the problem and good luck..

My hard drive clicks and the moniter turns off


Hi, you can isolate that problem to see what is the defective part;
1. Remove the hard disk connection from the board and its power then re-start the PC.
2. If the PC powers and initializes, then you can prove that the defective is the hard drive. If the same problem that it shuts down then. the next target is the power supply. If you change the power supply and it turns out success, then we have solved the problem, if not, next thing is,
3. Turn off PC, remove the battery/clear cmos, the memory and the processor for 20 minutes.
4, After 20 min re-install the battery, memory and processor. Without the hard drive when starting, lets see if it will boot without the O/S.

others, when you say the monitor turns off, does the CPU still working or not? Isolate also the monitor by powering it on and not attaching the communication cable to video port, lets see it the monitor itsel display by its internal video logo to be sure it is okay.

I have sony vaio desktop. My moniter keeps going off and on. Tried different moniter does the same thing. Could it be something that the desktop might be causing. Also, last year I replaced my power...


When you say 'on and off' you have not indicated if the whole power on the monitor is going on and off or if the monitor remains turned on but the screen display goes on and off.
Is the monitor power plugged through the socket on the pc or direct to a power outlet?
multiplug power outlet boards are often a source of power failure.
Did you try a different power lead for the monitor and b) a different wall socket?
If it is the screen display that is intermittent you should check the graphics card is fully seated (if it's a separate one)

The montier turns on then turns right off


Hi!
When a monitor display image for a second and then goes to black screen... there are possible reasons why this problem occur..

1. You need to check if the high voltage ballast transformer of your backlight inverter is about to be burned... the transformer is overheating..that's why you experience the monitor working for a couple of seconds and then it will shut off until the transformer cool down again and then it will be ready to work again...

2. Check also the backlight inverter if it is busted...the backlight inverter is the light source responsible for the image display you seen on your screen. If this are busted then all that you will be seeing is black screen

3. You need to check the power supply section for possible loose connections and possible blown and bad capacitors..

the ballast transformer has direct effect on power supply section.. when there is overheating transformer,,, the supply current from the power supply section becomes unstable.. and will not be able to supply the remaining good working ballast transformer.

In case you do not know, the ballast transformer generates high voltage for the backlight inverter to work....

Please be advise that if you don't have the knowledge, the proper skills and the right tools to open the back cover of your monitor and replace its part...don't risk it...

Otherwise, bring your unit to a credible technician and avail of warranty if there is any.....


Much appreciated if you rate this help...thanks...

My laptop moniter turns on as usual with the proper reading. I start in safe mode as normal..wait about 10 min and screen goes white


hello

"I start in safe mode as normal."

safe mode is not a normal thing during your windows boot sequence :)
if your display works ok until those 10 minutes of safe mode are over i would say that reinstalling your windows operating system will most likely solve your monitor issues :)
