No Signal Input

Hi,
Lately I've been getting "NO SIGNAL INPUT" when the computer is running and after I have turned off the monitor. When I re-start the monitor, I get that message. I have to manually turn the processor off and then re-boot to get back on. Doesn't do it every time.
Thanks!

Hi Larry,

Sounds like the monitor data cable may not be secured completely, there may be grease on the connections or one of the pins is bent. Disconnect the cable and use some pure alcohol/spirit and flush the connector pins (I prefer Contact Cleaner). Check if any of the pins are bent or damaged. If some of the pins are missing that is OK, some are not required. Connect it back to the computer carefully (don't just lean around the back and hope it's in...like I do ).

Thanks!!
Sounds like a logical solution. Did as you suggested, but since it didn't always do it, will let you know in a few days if it solved my problem. Thanks again!

Input Signal

Hi Matt,
I guess that it must be a different problem, since it did it again when I just tried to use the computer. Usually just moving the mouse does the trick.
So any other suggestions would be appreciated.
Thanks!

Larry, if you have any Power Management options turned on, try turning them off and see if it helps with your problem. Control Panel>Power Management. Also check in the BIOS and see if any PM options there are enabled and if so, disable.

Win98 doesn't always like to play very well with power management options.

 

i agree with johnb, ill bet that you were going INTO power conserve mode, but not wakeing up.

 

Thanks John, Joe, and Matt,
I went to Power Management and deleted whatever was showing either Always or Never, and it was replaced by Home/Office Desk. We will see if that works. As for checking in BIOS, I don't know how to get there. I'm 77 years old and the brain doesn't function too well anymore.
Thanks again, and I will let you know the outcome.

Larry, set the Power Management options to "Never ". This will disable all PM options. If this doesn't work, post back and someone will help you get into the BIOS and disable PM there if necessary.

 

Hi John,
I went back and put Never on all three options; that is System Standby, Turn Off Monitor, and Turn Off Hard Disks. Sounds like this will do the trick. Will let you know.
Thanks!

Opheim,

The message that you are seeing is often related to video signal problem. In that regard, I have to agree with Matt's opinion that it could be a hardware (cable) issue. The next time this problem occurs, look at the power button on the front of your monitor. A steady amber light indicates that the monitor is receiving a signal from the video card/or motherboard. Make sure you note the color of that LED and post back here.

Furthermore, I would strongly advise you to NOT use the power button on the front of the monitor as that creates excessive wear and tear on your monitor. Instead, use the power management feature (in Windows 98) to automatically turn off your monitor after a preset amount of time of inactivity. Since you have already chosen the Home/Office scheme, make sure that it's set so that it does not automatically turn off your hard drive.

 

Maverick - Is this true ?(guess you wouldn't have said it if you didn't think so) but it's the first time I have heard that and have generously used the monitor power button to shut the monitor down. I may have to change my ways I suppose.

 

Hi, Thanks for the additional info re: my "No Signal Input" problem.
Actually, I never use the monitor On?Off switch. I have a separate switch which turns the overhead light, monitor, and printer off and on when I'm away from the computer. The processor stays on all day, but I turn it off each night.
I believe that the little green light on the monitor stays lit when I have the No Signal Input. Will surely check it if it happens again. It's been ok so far today. Will keep you informed.
Thanks Again.

Personally i've never had any bad experience w/ my Win98 using the power management options. (Dell desktop PC). As long as your BIOS is fully ACPI compliant, you shouldn't be having any sort of major problems.

 

Yes it's true Bobmc. The reason why it's not recommended is because everytime that the power button is turned on, the capacitor has to be recharged fully before it can emitt the signals to the cathode ray tube. (Even in the off-state, the capacitor can and sometimes does retain a dangerous amount of electrical charge which is why the manufacturers warn the home user to never attempt an repair on their own).

The power management feature in Windows not only allows for conservative energy use, but allows for the monitor to be turned off w/ out "FULLY" turning off.

 

Thank you Maverick. I'll have to work on this as Power Mgt. was causing me grief sometime ago and had to opt for no PM. I'll see if I can't straighten out the problem then take your advice.

 

I haven't had the problem for three days now, so maybe it is fixed. The Power Management changes seemed to do it. I have other problems, but will try to get those solved with a new separate post.
Thanks to all of you who contributed.

Hi Larry, pleased to hear that the problem has gone away, at least for now. If you feel adventurous you could turn back on the PM options one at a time until you find out which one causes the problem. I would start with the PM option for the monitor only. I use this one and the hard drive one on my Win98SE system and have had no problems with them. The one that seems to give my system problems is the "System standby" option. When I used it the system would not "wake up" so have set it to "never ".

Good luck.

 

If you are using those settings on a desktop system, you are wasting your time. Those are power management features that are meant only for laptops. The obvious reason being they operate on batteries and desktops do not.
