PC is running but monitor doesn't

[zzeven]

Monitor makes a short beep then repeats. After a while (1-2 hours) it makes a longer beep.After that im shutting down the PC and then the monitor runs to. What's the problem with it?

 

[Aofekiko]

if you have another monitor or even a tv screen try connecting your pc to that, so you can see if its a problem with the pc, the monitor or something else

 

[zzeven]

I have already tried that and the PC is working .

do you know the model of the monitor? look for common problems with that specific monitor.

 

[zzeven]

Are the same : replace RAM , VGA ... I've tried all of em

i ment if you know the model of the monitor, its name, the company... stuff like that, and try looking for similiar problems people had with this specific monitor,
and another thing to check if your screen is broken, most monitors have some kind of buttons on the side or the back to controll the options, if you use them, is the screen showing a window or something like that?

good, try pressing the buttons, is it working?

 

[zzeven]

None of them

 

[Aofekiko]

None of them

then i assume the monitor is dead. how long did you use it?

 

[Aofekiko]

None of them

and does the monitor uses a LED or a little light that indicates that it is actuallr getting power?

 

[zzeven]

4-5 years but after like 1-2 hours it starts to make a.long beep after that i turn it off and its shows like digital, analog and when i power it on again it works

 

[zzeven]

It has a Led behind the power button and its blue that represents its on

are you mooving the monitor by chance, many monitors have a really bad conection with the cable and every tiny movement can destroy the link between the power and the monitor or the link between the cable from the pc to the monitor. and can you explain the "digital analog" is it wavey or sqares?

[zzeven]

Its square and yes im moveing it but i did this a lot of times and i never had this problem

 

[zzeven]

Oh sorry i watched ur link and its not square like that . Its a shape and in that shape writes analong then digital

i not sure, but if you have a spare cable try using your spare one, see if that changes anything.
if the monitor supports more than one type of cables, for example vga and hdmi and you are using hdmi, try vga, see if that works, i know vga is really bad but if it works then untill you will get another monitor you can work with that.
Another thing is, dont move it at all. do a test to your monitor. go watcha movie or something like that so you can keep a close eye on your monitor, while not getting bored and not touching the monitor at all, if you want to the test to be accurate as possible, do not even touch the table, you need to find the problem by the prosses of elemination. so slowly we are getting there.

basicly:
step one: spare cable
not working?
step two: another type of cable
not working?
step three: not moving/ touching the monitor at all for 1-3 hours while it is working (not idle on the desktop)

It is probobly the window when it's not getting any signal and tries to looks afor any other signal, analog, digital or both http://
the picture willl explain it
basicly, analog is really bad compared to digital.

Im usein a dvi adaptor to vga because my video card has only that and dvi-i . But how after 1-2 hours the beeping gets longer and after that starts?

As i said i assume it is the screen loosing connection with the cable,
another possibility is that the power supply is the problem, and that every little beep the the screen trying to turn on but runs out of power, but when you have a long beep it turns on because it has power and the beeping does not stop so it makes the beep soud like a long one but actually its just that the short beeps are the problem (all that according to searching common problems with the Samsung SyncMaster 940Bf
anyway, its a sighn to buy a new screen, most monitors last for 6 years max. so your monitor did his fair share

 

[zzeven]

But i've tried the PC on another monitor and it started in like 4 seconds with no problem.

by power supply i dont mean the PC's power supply, the external pwer supply, the big heavy box on the power cable of the monitor, according to what i saw, the monitor has an external power supply... am i wrong?

 

[zzeven]

No. Urright.

 

[Aofekiko]

No. Urright.

try the 3 steps I tolled you to try, if that does not work then you can try getting yourself another power cable with the same voltage and specs, but if you do that i just reccomend buying a new monitor, a new cable for such an old monitor will be hard to find
