The VGA cord are good!! but still it tuned black in few seconds, but it has power..

Is this a Gateway FPD1960 monitor? If so the power supply inside of it died. It is a common problem with these. I repair the Gateway FPD1960 monitor so if you want to trash it let me know. You can contact me at sure-power(at)nc.rr.com

Sorry to have to tell you this, but this is common in LCD monitors. The reason that it is going black when it boots is for one of two reasons. You either have a bad power supply that powers your LCD or your LCD's backlight is blown. These can be repaired or you can purchase a new one. But if it goes black 9 times out of 10 is because the backlight is bad. These can be repaired!

Sounds like a bad solder joint on the printed circuit board. Once it heats up then it no longer makes good contact and the monitor goes black until it cools down and makes contact again. You could resolder it if you knew where it was but monitors are dangerous to go playing around with as they can hold very high charges of electricity in their capacitors that are very dangerous. It's a throw away world. Go buy a new one.

Ive seen this on other monitors. Look for a 1 and 2. Some monitors do NOT auto detect a signal, and this one might not. Look for a way to set the monitor from Digital input to VGA input. Try that and see.

The monitor is doing a self test a finding an error.
The lcd has three parts, the screen plate(windows)/the logic(vga)/the
inverter(power plug). Parts that go are the backlight ccfl's, behind
the plate, and parts of the inverter, ie capacitors, all three take a
bit of power from the inverter. The self test check that all the lights
are ok and the inverter is ok, else it switchs off, ie if 3/4 light
work it will switch off(my own case), hence the on chech error then
off, However sometime there are stages of on/off ie on/ but no screen
display, if that is the case the following may be of help...if you put
bright light at an angle close to lcd can you see a windows shadow,
text icons etc, ie still logic power passing,then .... (from a.n.
other) after two weeks searching I finally find doctor living stone

the takening the case bit off is like opening your wallet a second time
after buying a new LCD, but you must! smallest two screw driver's flat
headed, practice using two pennies stuck together()with your fingers
after, one little () move and inch and {} again, with the case , it
does not break, just need to lever open
[once open you realize they somehow put that old briefcase clip
inside!] also note the bright light test to do first to see if can see
a windows screen , and that capacitors are one for a number of things
that a make a inverter work! there a transistors as well, given that
however, to replace all the capacitors on my inverter, was 11
capacitors, cost me $11 (uk ebay) and already had the iron and solder.
So only cost me me $11 to try and see but no luck , still fun and I
still can see the screen for 2 sec' at a time plus I have a spare set
of caps now in the event that the new one do go burst! you have to
laugh really, what next , a new on/off button, as you work though the
whole inverter mmmMMMMmmmMMMMmmmMMMMTim
Berners-leeMMMMMmmmmMMMMMmmmmcome back all is not
wellMMMMMMMMMMnnnnnnweek later land sight
mmmmmMMMMMMMMMmmmmgggggggg(from
another a.n other)Generally, if the screen went out quickly, it was the
inverter. If it went out over a slow period of time (flickering etc..)
I would bet it is the lamp.replaceing the lamp should be pretty
challenging. as that requires complete breakdown of your LCD,
extraction of your dead lamp, and soldering in your new lamp... but I
would like to say that I it did this after realizing it's 2 x kitchen
strips inside [========] with wires that can connect back to the
inverter with out any desoldering(ie kit assembly/dis) with the outter
case remove (glass plate safe away) I could reconnect and see that 3/4
were working (i!i hardcard ) cause the inverter to switch off after a
secound ! order bult and replace and going
to cheap and see if I can get away with fitting a 15" in my 19' as it a
1/3 of the price ! the market as drop out there, hope the inverter does
not miss the length, or the screen out
put.http://www.lcdparts.net/howto/troubleshooting/LaptopCCFL1.aspx OR
