The message it is displaying indicates that a VGA cable is connected and is not sending signal, or is sending a Monitor Off signal across the VGA cable. The motherboard battery will have no impact on this. If you are using something other than a VGA cable to send the signal to the monitor, then you should ensure that no VGA cable is plugged into the monitor, or the source on the monitor is not using the VGA connector.
when you say monitor can't be found did you mean the monitor has no reactions when you turn on your pc?
here are some test you may need to do to know which part is faulty 1. Turn on your computer, did it display the monitor's logo on screen? When it does monitor is good, when only blank screen it could be the vga cable or the video card. 2. See if the led indication lit. When it lit to steady green, it's good signal is coming in from the video card. It should be followed by screen display. If no display it could be the backlight inverter lamp busted or faulty inverter board. When lit green then turns red, no signal coming from the video card. Check vga cable if fix properly to both monitor and video card. Or may need to reseat properly connection of video card from the motherboard. If no led indication lamp, then monitor is dead. Check ac power cord for continuity using multitester. Check power supply section in the monitor, replaced bulged or blown capacitor with exact value, this components were the first to get affected when lcd monitor failed o turn on. 3. When computer was turned on got display and then monitor turns black, go check the vga cable, Fix the connection properly or may need to replace it with new one. 4. When no signal appears or display blank screen after logo, then check video card. First remedy is to disconnect it the reseat properly to the motherboard. If this have no effect change your video card.
go follow these steps and let me know which is closely to your problem so I can give you a good advise.
Check your signal cable from the system unit, if this persists, then its the display that is not working or try opening the computer, replace is ram with another chip, again if this fails, remove its cmos battery, unplug all the power cables from the mother board, leave it for atleast 20minutes, replace everything and power it on.
disconnect the signal cable and power on then see the massege on monitors screen "NO SIGNAL CHECK THE SIGNAL CABLE"if it appears then monitor is ok if not then monitor is faulty check the signal cable and replace it if faulty problem will be solved
I would check the LCD against another monitor. It does not have to be a LCD, a regular monitor will do.
This will tell you 2 things, 1. The Video card is good or bad, 2. The Cable is sendinf a good signal.
If when you startup the monitor, you see a display and then after a few seconds it display's a no signal message, this is consistant with a Bad cable or cable ends. or Bad VGA card from computer.
Hope this helps. Good luck..
P.S. If you have move the PC, you may want to open the unit, and re-seat the Card. If the card is not making a solid connect on the board, it will display these syptoms.
hi..i think you have a problem the CPU/Computer that's whystays on screen for so long.1st step check the IDE cable connection form the mother board to Hard Drive and 2nd check the memory or check all hardware`s.Good Luck and Have a nice day
Check your VGA connector (from monitor to PC), namely the pins in the connector. It's pretty easy to bend a pin, so that it doesn't make the connection. If you happen to do this to the connection present pins, then the monitor won't know that it is connected and will just display the message you are seeing.
Hi, sandjkroll, this kind of problem could be because of ur monitor or even because of the on board display card on ur motherboard. To check ur monitor, u unplg display cable which goes to ur cpu and the power cable which goes to ur cpu. Them connect the power plug to mains, so no cable from the monitor should go to the CPU. Then u swithch on the the poower suply, and on the monitor. I If ur monitor displays elongated screen still, and shows signal not found,and no display comes that means ur monitor needs to be send for service. and if there are no elongated screen and says no signal found, ur monitors fine, ur motherboad has a problem
I'd try this monitor on a spare computer. It sounds like the video card (motherboard integrated or otherwise)is not putting out any video information or missing sync signals. The monitor must receive these signals or it will go into standy/sleep mode.
If the computer has integrated (on motherboard) video, check your bios settings to see if it is properly enabled. If it has a slot video board, then try a different video board. Your present board might be dead.
Another possibility is a bad cable connection. check the connectors for bent pins. Assuming the connector is the standard HDB-15, it is easy to bend a pin over.
