HP Pavilion F50 17" Flat Panel LCD Monitor - Answered Questions & Fixed issues

The PC might have a bad VGA output - it should work at the default level without the driver. I'd return the PC to the store. If you have another monitor, try it out to verify the VGA output is bad.

According to the HP spec from HP website: This monitor does not have built-in speakers so you will not get any connections for the sound setup.

Morelikely to be backlight inverter board problem, or worst case will be the CCFL assemblies, this is vey old 15" LCD monitor, not sure if it is even worth to put money into it.
You will have to open it up and check the 12vdc feeding the inverter board and also check the surface monuted fuse on the inverter board.

the drives laser is probably bad. cheaper to replace the drive

Try it on another PC first, if it still does not work then you will have to open it up. If you are going to DIY repair, then please read below and look at my albums so you will know what to look for inside.
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
Post back what you see inside so we can guide you further and it will help out other people in the future also.

you have to pop out the plastic that is covering the screws of the base...

Problaly you had a magnet near by that caused that Dark Shadow.

unscrew it or unclip the lock

you have logged this under a LCD screen problem, surely you are on about a mobile phone? This is normal for most mobile phones when they are first switched on although 10 minutes is very excessive. If its a constant problem then do contact support

well this might be because the power cord of the monitor is loose contact so check it. if it is ok then check the power options settings in the control panel- performances and maintenance- power options- power schemes you will find turn off monitor option select the required option from drop down list and apply the settings.

good luck

You can find motherboard for most systems on EBay

That is a generic search for an HP motherboard. You will need to refine the search for the model of your tower (F50 is the model of the Monitor)

If you can make out a faint image then the fault is a backlight problem.
The fault could be an inverter board or the CCFL lamp/s

You may have a problem with the screen's back light. It could be a ballast that may go bad or the light itself may go bad or loose connections in those areas may cause it. Check as well the data cable or check if a different cable would work.

"monitor not cooperating"
Try another cable for the monitor, or try the monitor on another system to check the monitor & cable.
Check the switch(es) on the monitor itself.

Did you try to hold down the key that says Fn then keep on puching the up arrow key. This should work.

I'm seeing alot of leaking caps on the power supply cause this issue. It can also be T-Control board faulty, or even main board. Is it flickering constantly, or once warmed up?

Try changing the cable that connects the monitor to the computer, that might improve things slightly, but because you said that it works for the first 15 minutes I'm skeptical that the cable has anything to do with it.

The monitor is near the end of it's life. There's not much that can be done.

check using variuos frequency> the option is in display adapter properties.
right click on desktop>properties>settings> advanced>monitor>screen refresh rate.
