Re: monitor keeps saying self test everything working...
The self test thinks nothing is connected to it it might be the cable or the input circuit. not an easy issue to verify if you only have one input. most often its is the internal board with a failed input circuit. you can only open the unit and test the vga cable continuity. as most have a 1 year warranty you might want to check on yours.

Check it is proerly plugged in and there is power getting to it. Then check the fuses at the pug and then the internal if you get no joy with the plug fuse.
If it has a power supply check the power supply
first check with your both power supply out put is coming 19 Volts dc. if its not coming check with multi meter primary and secondary of your adopter continuity.if no continuity replace with proper working adopter.
Hi, Please check if all the cables are properly plugged in. If yes, then remove the vga cable with the blue plug from the back of the monitor, make sure that you do not remove the power cable. if you see monitor self test or any colors on the screen it means that the monitor is fine. but, if there is no display still you need to change your monitor. then the problem is in the tower, please check the power supply if it is working or not. If yes, the problem is either with the mother board or the memory.
Believe it or not but theirs an order in witch you should connect up a compute,r but first make sure that there is only 1 VGA port ie (monitor socket) on the back of it. But if theirs 2 then try the other one. Other than that try this: Unplug EVERYTHING! even the power leads from the back of the monitor & pc. 1.Press the power button on pc & monitor to flash out any power left in them. 2.plug in & tighten the VGA cable to the pc then to the monitor if required. 3.plug in all other peripherals ie USB / MOUSE / KEYBOARD etc... 4.plug in the power supply to the monitor then the pc. 4.Switch on the power supply to the monitor first then the pc. 5.Switch on the monitor by it's power button then the pc right after it.
Your monitor is most likely fine. That message is the monitor telling you it's not getting any video signal from the computer.
If you're hearing all the sounds that go with a normal startup (usually a beep from the motherboard, then hard drive activity, finally the normal Windows startup sound through the speakers), and seeing that message, then you may have a monitor problem. You can try another monitor as a test.
The trouble is probably that the computer is turning on, but not actually starting up. This may be due to power supply, memory, processor or motherboard problems. Or one of the drives or expansion cards connected to the motherboard may be keeping the system from starting.
Make sure the memory modules are firmly seated in their sockets, and disconnect everything else but the power supply. If the motherboard, processor and memory are working, the system will start and you'll see something on the monitor. Then you can start reconnecting parts and see when the problem returns.
This problem often occurs in samsung SyncMaster LCD monitors.
solution is open your look for the LCD monitor power supply module
(which have PCB connector to the AC power), on that board look for
capacitors, now look for broken one which upper part is bloated, like
the image below:
If you find a damaged capacitor as in the picture then you should replace it with the same value.
Self-Test Feature Check (STFC)
Your monitor provides a self-test feature that allows you to check whether your monitor is functioning properly. If your monitor and computer are properly connected but the monitor screen remains dark, run the monitor self-test by performing the following steps:
Turn off both your computer and the monitor.
Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove Analog (blue connector) cables from the back of computer.
Turn on the monitor.
The floating 'Dell - self-test Feature Check' dialog box should appear on-screen (against a black background) if the monitor cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains green and the self-test pattern will scroll through the screen continually.
Turn off your monitor and reconnect the video cable; then turn on both your computer and the monitor.
If your monitor screen remains blank after you use the previous procedure, check your video controller and computer system; your monitor is functioning properly.
