Monitor saying no signal?

#1SkaterUBPosted 3/4/2014 10:12:54 AM
My family has an HP PC that is years old. Everything worked fine but they said that the monitor has no signal.

The monitor turns on and runs through the channels but comes up with nothing and goes back to sleep. I disconnected the VGA cable and reconnected them but nothing happened. I don't know what to do.

Anybody have a clue?

First, Is it set to the proper input channel? As in, is it set to be displaying things from a DVI connection rather than the VGA Connection.

Second, does a different monitor work with the computer?

Lastly, does that monitor work on a different computer?

at this point I can only offer general troubleshooting tips to eliminate variables.

try another port or try another monitor using that same port

try a different cable

Lastly, does that monitor work on a different computer?

that too.

I can't even change any input channel. It searches and then sleeps. I can't change anything.

I don't have another monitor or computer to test out your other points or else I would try. This is not at my house

No one has a laptop or something you can borrow long enough to test it out?

I'm sure they have neighbors or friends with a computer.

If you have a laptop, you could bring it to where the monitor is and hook it up to the laptop.
Or if it's feasible, you could take the monitor home with you and hook it up to your computer. Since apparently it's for your family and it's not working anyway, they shouldn't miss the monitor. Conversely you could bring an outside monitor there and see what happens.
Of course if that's not feasible for logistical reasons, then don't mind me.

Also, this is probably not the case, but does the computer maybe have two VGA outputs (one on the motherboard and one on a discrete video card) and you're not connecting the monitor to the active output (if there's a video card, typically the output on the motherboard would disable itself) ?

He's old, we're lucky he has a computer.

I don't see any other VGA connector. Maybe I'll try and take it home and test it on my computer. I just don't understand why this happened.

Well, if the computer is old too, it's not unheard of for a component to fail - the monitor cable, GPU, or something else in the computer. Computer hardware doesn't actually last forever...

EDIT: As long as you're checking things, you might just double check the pins on the monitor cable - both ends - and make sure none of them are bent. A bent pin can easily cause it to not work.
