SOURCE: monitor goes black

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!

Undo what you did & it should hopefuly work.
Next time don't be overconfident and do things that you are not sure of. It doesn't hurt to ask someone who knows. Here you are lucky to escape with this one. I've come across cases where people have ended up short-circuiting their gadgets beyond repair.

If you have the previlege of having a manual, refer it, read every word carefully and then go about doing things on your own.

SOURCE: Picture goes black at random intervals

There are 4 c5707/5706 in the inverter transformer driving circuits, the cause of the problem was due to poor solder connection in the bias circuits of the transistors. Make sure to check that after you install the new transistors otherwise you will blowthem up. Common problem with this model. When the circuit drwas too much power from the power supply, it will shut itself off to ptotect itself.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums

I have a dell studio 540 desktop, I need to restore to factory settings but my monitor will not stay open. It opens for a few seconds then immediately goes into power saver mode and turns off, how can


I see two things here, but need clarification;

1) Monitor goes to Power Saver Mode, then turns -> OFF?

Sure that monitor didn't go into Standby Mode?

2) Why are you performing a restore back to factory settings?
Pick up a virus?

Primer;
The monitor receives a signal. A video signal. The video signal comes from the computer.

If the monitor is NOT receiving a video signal, then the monitor will state No Signal.
This is for older monitors.

New monitors do not state No Signal anymore.
It's Power Saver Mode, or Sleep Mode.

If the monitor is truly OFF, the Power On button will Not be lit up.
Or the Power On LED light on the monitor.

Monitor power on LED is lit, or Power On button is lit?

Monitor is not receiving a video signal;

Use a monitor cable from a KNOWN to be working monitor, for a temporary test.
OR,
Use a Known to be working monitor, and it's monitor cable.

Need to find out if monitor cable is good.

Monitor cable checks out good?

Then problem is computer.

The two leading issues with desktop computer failure, is;

1) Computer is dirty inside
2) Power Supply inside computer is bad.

HP w2207 no vga input signal, no dvi input signal monitor goes to sleep


There is no signal coming from your PC.
excuse some of the solutions as sounding dumb, but we have to explore all possibilities.

Check the power cable going into the computer
Check the power input disconnect switch on the back of the power supply and make sure it is on
If the pc is plugged into a power bar, make sure it is turned on and the breaker isn't tripped
press power on the PC and make sure the lights are coming on.

now for the solutions that may actually help.

disconnect the power from the PC
if the video is on a card, remove and re-seat the video card
hook the power back up, connect the monitor and try again.

the CMOS on the computer may need to be reset.
I hate totally clearing the CMOS, so what I usually do is remove 1 stick of ram and power up. If the system is alive again, power down, put the RAM back in and power back up.
If that doesn't work, turn the system off, put the CMOS jumper to the CLEAR position for 15 seconds, put it back to the Normal position and then power back up.

Basically, if the monitor works on your friends system but not on yours, the the problem is your system, not the monitor (assuming it isn't working fine til it gets into windows...if that's the problem, you have a driver or configuration problem)

Acer ASpire M1100 shows No Signal on monitor


Any time a monitor says "no signal" that message is originating from the monitor itself, and not from the computer. A monitor in a room by itself with no computer will say "no signal" for a brief time, if it is turned on. So, if you have tried other monitors also with no luck, then the problem is either the video adapter of the computer, or something that is keeping the computer from booting in the first place (power supply, hard drive, memory, motherboard). A power supply can be tested with an inexpensive tool. Everything else needs either a swap out with a known good stand-in, or else an expensive tool to know if it works.Does the fan come on when you turn the computer on? If so, maybe more likely to be the motherboard, hard disk, or memory. If not, more likely to be the power supply.

My gateway computer power light blinks and moniter says no signal.turn it off held then power button on for 30 seconds.then turned it back on.same as before.


Hello,
I don't think this has anything to do with the monitor since it is showing "no signal". this is an indication that the monitor is working.
Problem is from the connection between the computer and the monitor or from the computer itself.
Check the VGA cable and make sure it is firmly fixed into the computer and monitor.
Open the computer case, disconnect the keyboard, mouse, and every other thing apart from the VGA cord, then try again.
If there is still no signal, turn computer off again, remove it's power cord, then remove the system Ram, clean it and fix it back in. Then make sure the VGA card is well fixed into the mother board. After that, connect only he VGA cord and try again.
If non of the above seems to work, connect the computer to another monitor, and connect the monitor to another computer in other to confirm which is having a fault so that we can focus on it.
Keep me posted.
Good luck.

Monitor will come on for 1 second and then go blank and the power light go from blue to red then if you cut power back on it will come back on for a second and then shut off


moniotr switches into power save mode when it is connected to the computer and there is no signal for the computer. Try following the steps below which i recomended for another poster as well

Unplug the monitor from the power
Unplug the monitor from the computer
Plug the monitor back in.
Try turning it on.

DOES IT SAY "NO SOUCRE DETECTED" or soemthing like that???

if it DOESN'T it means there is something wrong with the computer.

if it DOES:

plug it back on to the computer, turn the computer power off.
Press and hold the power button on the computer for about 15 seconds.
Plug the computer back on.
Try turning the computer on.
if it's not turning on again there a problem either with your monitor cable, or the plug, or the video card plug. It is unlikely that your video card is broken if you hear no wired series of short and long beeps when you try turning the computer on.
Good luck.

The monitor shuts off. Turning the power off


the monitor is going into power saving mode ... it can happen if it is not receiving any signal from the pc ( pc is not running or booted properly, bad video cable connection monitor to pc) or the pc is itself in suspend/standby mode.

While trying to change channels, my t.v. displayed ''no signal'' and then shut itself off. Now, when I turn it on, it says no signal and turns itself off after a few seconds.


Turn the television on and as soon as the screen turns on repeatily press the input button or change the input to whatever input you are using from a source device. As long as you change it to anything other than RGB.

Your television is essentially a big computer monitor with multiple inputs and a tuner. When using your computer and shutting it down the monitor will go in a power save mode. You don't need to shut off your monitor due to this power saving mode. When you power up your computer your monitor automatically turn on.

With the VIZIO and the RGB (computer) input the television will act just like a computer monitor. When you have a computer connected it will power down automatically when you shut off your computer. When you turn your computer on the VIZIO will automatically come out of standby mode. This is through RGB only.

This is normal operation for the VIZIO but can see confusing when nothing is connected to the RGB input. If you change your television input to RGB it will sense no signal on the input and will go into standby mode after about 5 - 10 seconds. If you were to send a signal to the television through RGB it would automatically kick on.

Computer monitor flashes on then turns off


Try the monitor with another computer. If it works, the video circuitry (whether it is on-board or a separate adapter) in the Gateway is the problem and needs to be replaced. Otherwise, the problem is with the monitor itself. From your description it is probably the Gateway's video that is the problem since the power light on the monitor remains green indicating that it is seeng a signal, but not something it can properly interpret, i.e., one or more of the control signals are shot.
