Hello, sorry for the question.
I have a labtop that the screen goes really black and you can hardly see the info on the screen.
It happend just like that, one day working the next day when turned on it does not.
I know the battery is bad it only holds about 30 minutes of energy but I always have the lab top plugged in.
Now is the screen broken?

Can I get the screen back?

I also have a hook up on back for a another monitor I plug into with a monitor but do not know how to get that to work .

Thanks for any help in advance.

Comment by rrakness, posted on Jan 20, 2008 Thanks for the help but that did not do the trick.

I plugged in the monitor and hooked up and turned on the labtop

The monitor said:
please check signal

Nothing came on.

I even tried another monitor and that would not come on either.

I heard something about pressing fn- f5 or f7 and tried those things and did not see anything .
after rechecking the battery it only holds about a few minutes of power.

Thanks for any help

The video resolution and/or frequency that's set in windows is not supported by the monitor you have plugged in. Restart the PC in VGA mode (hit F8 after the BIOS messages but before any Windows messages) and change the video settings to something basic, such as 800 x 600 @ 60 Hz. Then restart the machine normally.

It is a little tricky problem. But anyways this is due to small capacitor leak you have to replace it to make it work well. You can identify it by seeing the top of it. See the below pix for more info.

While connected via VGA cable Viewsonic VG920 Monitor has an error stating "out of Range" . H. Frequency 157 Khz V. Frequency 59.8 Khz

It was pretty tricky without instructions but trial & error brought me to a successful resolution. This machine comes from the factory set to connect directly to a television with supplied RCA cable. Do that before you connect to a VGA monitor. Using the remote control, press setup and then go into "preferences" and look around for "video" and then to "VGA". Once you click "VGA" the TV screen goes frighteningly blank. The next obvious step is to hook it to the VGA cable and VGA monitor. If your computer is also hooked up and on to the monitor there is no karaoke picture. Shut off or disconnect computer and presto, there it is. <br>

Blank screen

if this goes blank randomly, it could be that there's something wrong with the monitor or its starting to die on you. if there's a factory reset button on the monitor, you can try doing it and if that is still not going to resolve the problem then just get it replaced if its still under warranty and if not then get another one.
