You can use an external monitor to test it. If the external screen does not display anything, then your GPU and or motherboard is dying. If your netbook works good with the external monitor, then your screen is dead.
You can check the operating system and application using this Norton Utilities: http://download.cnet.com/Norton-Utilities/3000-18512_4-10907620.html
Change your screen resolution to the highest setting first, in control panel, appearance/ themes. Next Push smart button on bottom right of monitor. Cinema mode should be highlighted hit autoset on monitor. Next hit the FUN button and highlight the 4:3 screen setting. This will expand your image to fit the screen without giving it that stretched and distorted appearance.
• 1) TAKE OUT YOUR LAPTOP BATTERY • 2) REMOVE YOUR AC ADAPTOR CORD, that's the wall power, remove it. • 3) NOW HOLD DOWN THE POWER BUTTON FOR 30 SECONDS.
That will drain any static electricity that has built up on your laptop
system board and many times fixes the problem of a black screen. After
the 30 seconds re-connect your laptop to the wall power and hit the
power button normally and see if the laptop comes back up.
I think there is a problem in Monitor's Power Supply unit which integrated in the base board of Monitor. If u expertise with the service then carry on. else Pl contact a Local Service professional to solve the problem
Try a different monitor, I am sure this sounds overly simplistic to you but, I have seen in my customers have just that, a bad monitor. If another monitor does the same thing, then you should try another video card.If the video in on the motherboard, there should be a AGP, PCI-e, or an empty PCI slot to put a video card in.
Assuming you changed all the caps and did it correctly.
IF you get flickering, It could be a transistor on the inverter board.
OR !!! and probably more likely,
It could be one of the bulbs in the lcd itself is failing. It only
takes one bad bulb to stop an inverter from firing up !! You can check
them one at a time if you have another working monitor.
If you do unplug a good bulb from the good monitor and try each of the questionable ones, one at a time.
Doesn't have to be a gateway monitor to test it, just needs the same backlight plug.
HP's are known for bad capacitors in the power supply.
Replacing them is simple if you know how..not so simple if you don't.
Try your local TV repair centre. It should not cost alot to have the capacitors replaced.
I have had the same problem. I've just managed to get the monitor working again by VERY QUICKLY navigating through the monitor setup menu to the 'factory reset' option and hitting reset before the screen had a chance to blink off.
The problem I had is that the monitor suddenly goes black, but will come on for five seconds if I switch it off and on with the power button.
In that five seconds, I had to... >Hit the menu button >then hit the '+; button once >then hit the menu button again >then hit the '-' button >then hit the menu button one last time
The above brings up the menu, scrolls up off the top of the list to the last item on the list (Factory Reset), selects Factory Reset, selects 'All settings' and resets the monitor.
I don't know if this is a permanent fix, but it just worked for me and mine has been doing this intermittently for the last week.
Give it a try, it's frustrating and will take a few tries, but it can't hurt.
