You will first want to verify all the cables are plugged in securely at both ends. If they are, your monitor is likely faulty. You will want to have it looked at, or simply replace it.

    Actually, my goal in posting was to fix the monitor. Had replacement been on the menu I would have already done so.

    If the monitor is no longer powering on, it will be quite the task to troubleshoot the source of the issue and then replace the needed parts. It would probably be cheaper to replace it. But, if you have a multimeter, you can pop open the monitor, set your meter to Volts, find the positive and negative post on the power, and test to see if it's even getting power.

How do you watch tv on This monitor?

The hp2509m is just a monitor it doesn't have the ability by itself to watch TV.whoever told you that it had this feature was misinforming you.
However any monitor connected to a computer can display video streamed from a TV station over the internet with the right software. Try a search forfor a TV aggregator on google to find one to fit your needs.

Uninstalation of monitor driver HP2509 stopped monitor to display.shows blank screen in vista desktop

The monitor driver only tells the video card which video resolutions are supported by the monitor. The video card is probably set to the wrong resolution. You can boot into safe mode, set the screen resolution to one the monitor supports, and you should be good to go. You don't actually "need" a monitor driver.

Hp 2509m picture stays on for a few seconds then goes to Black

I had the same issue, It actually turned out to be the backlights themselves. An easy way to check this is by shining a bright light on the screen while its on. you should be able to see the picture.

Hi Kevin,
My daughter has the same problem with her laptop, do you find that when you move the screen slowly back and forth it either stops or gets worse ?
You will need to take your laptop in to an HP dealer and let them have a look at it.

When power on u can see the screen for 4 seconds then it turns black .. Can anyone help me!!!...PLZ...???

This can be due to a protect on the board as it trips due to a short or malfunction within the main board.
Also it is important that the voltages be measured +B to the circuit secondary side.
Finally check for heating components or burnt component which can lead to the suspected part. A faulty IC within the processing drive circuit cannot be ruled out. So a need for a schematic check up.
