Monitor using 100% cpu and on the blink

Hi Everyone A couple of days ago my monitor went on the blink,(every 3 seconds the screen would show for like for a millisecond then go blank) then repeat the cycle. I changed the monitor and that one was ok. So i put the faulty monitor back on and back came the problem. Well for one reason or another i left the monitor plugged in but switched off,(by the monitor). Today i switched the monitor on and it seemed to be working ok but my computer was running slow,so i clicked on the task manager only to find my cpu running at 100%!!! I then changed monitors again and every is working ok,(cpu 0-2%). I then rebooted and back came the blink. Has anyone got any idea's?

    I have the same type of issue. The differance is mine continues to flash on and off, less than a second at a time. I changed monitors and computers. It is deffenitly a monitor issue. Any Thoughts? Thanks

    sounds similar to my problem - don't know about cpu usage but screen just flickers on and off - i did find if i put it into sleep mode when i "woke it up" by hitting the space bar or jiggling the mouse, on about the third or fourth try it works. It seems as if the main power button isn't working prperly eith as when i push it, it doesn't always respond.

    i forgot to add,apart from the blinking and power button not working, computer has slowed down significantly, I have defraged, done disc cleanup, uninstalled rarely used programmes and used the pc doctor programme on this computer but no use.

    It starts ok and sometimes after 1 hour and sometimes after 5 hours it just goes off for 1 sec and then returns to normal. After that it works fine for anther 1 or 5 hours.

Video card is plugged via DVI cable? If the board in the flat panel is going bad ( main signal pcb) video card can be going up and down scale to control its sync with no luck, causing the CPU useage problem.Only ever seen this once. Normally, the monitor will not cause and performance issues other than you cannot see anything.

Hi there,

Yes i do agree with you there is no problem with a graphic card,and i suspected it to be a problem with the cable which is used for connecting but it was fine when you swapped the monitors however i would still suspect on the slot where the cable is connected,may be you should try samsung service center before you decide.

Post back for more solutions we will be happy to help you.
Hope this helps.
Cheers!!!!

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)

No Display on my Samsung 204B monitor

If you know how to open it up and get to the power supply you will find three capacitors 2-820uf and 1-330 @ 25vdc 105o.they will have puffed up tops replace them. FYI the monitor has a 3 year warranty.

Monitor Blinking

HI SrFixer -
Since you were able to attach another monitor to the computer and it worked, that would indicate that the problem is not a computer problem but a problem with either the monitor or the monitor cable (data). Try another monitor cable on the monitor that didn't work and see if that works. If it still does not work, then I am afraid that your monitor has gone bad and needs replacing.

Hope that helps

Green light continously blinking in samsung sync master 753s

1. cpu problem. why because of there is no signal output from cpu to monitor. the led blinking means there is no vertical, horizontal signals from cpu to monitor.

2. your monitor connected to another system.

3. neck board dry points.

4. cheak the display cable. 13&14 pins are horizontal, vertical signals.1, 2, 3 pins , R G B , 6 ,7, 8 pins R G B ground ( coaxiler cable used , meshed wire is ground )

Monitor is busted!

If your pc works on another monitor. I would recommend you buy a new LCD monitor or a used CRT.

The best solution if your computer works is to buy a LCD screen, I've thrown out my 17" crt screens they aren't worth anything these days. You can get a used crt from ebay


Over here where I live I bought a used crt for 25usd thats was over a year ago.

Theres really no point in trying to repair the screen if its broken, buy a working one or a brand new lcd.

Good luck.

Monitor went black

Same with mine a couple days ago. I've been told the contacts have oxidized and need to be cleaned. It was going to cost about $80 to fix and no guarantee how long it would last so I just bought a new monitor.
