When you turn on the pc & monitor, it all works fine for about ten minutes. Then the monitor jusy goes blank. Then you have to power down, restart and mess with the contrast and bright to get it to come back on. It then goes back to blank in about ten minutes?

Re: HP mx 70 Monitor
This is a problem usually with the Power Supply unit inside the Monitor. Often it is the Electrolytic Capacitors arround the Heatsink area. They dry out and go faulty.. It is generally a job for the "Shop" I get them all the time... But in saying that intermittent faults are the hardest to find.. If you do take it to a shop, ensure you get a firm "Quote" and explanation B4 proceeding.

It doesnt sound like a windows problem. A simple test for this is to unplug the vga or hdmi cable from the monitor then turn it on if it has power it should say no signal. Also try either another power cable to the monitor or change the fuse. Hope this helps.
If you get a flashing screen which show your screen for few minutes and then goes blank it may be an issue with the Monitor.
Try to restart the computer and go to BIOS setup screen. If you experience the same issue in BIOS then the monitor needs a repair or replacement for sure.
Power drain would be a better solution in this case. 1.first shut down the comp 2.unplug the charger 3. remove the battery and after press and hold the power button for 60 seconds without any charger and the battery.After the 60 seconds replug the battery and the charger and turn the computer .
I also have a hp w1907 monitor which also powered on for a second and then go blank with the power light still on.. it was out of warranty so I had no loss so I took it apart..I found one of the wires broken at one of the backlight bulbs { becarefull they are fragile and there is four of them, two on the top and two on the bottom... and the lcd screen is very fragile } I soldered the wire back on and it all work fine... just remember where all the screen parts go.
1. You can see images on the screen for a few minutes. That means there is nothing wrong with your computer.
2. When your screen goes blank, if you disconnect and then reconnect the monitor, it shows fine again for a few minutes before going blank (or dim) again. That means the problem is not with you video card.
3. It always shows the image after reconnection for exactly a few minutes before going blank again. yes? this means that there is nothing wrong with your cable.
Conclusion: Sorry, but you do not have many options. I bleieve that the problem is with your monitor that's going bad. Its far cheaper to get it replaced than to repair it.
sounds like 2 posible fings.
1.you have a virus wich you need to clear out.
2.you vidio card is damaged or a part is missing wich can make the prob.
this way or a nother contect a tech its the only way.
I would say don't turn off the monitor at the switch at all unless you are not going to use it for a long time. I just leave mine switched on and the power save blanks the screen if I am away from it for 20 minutes. I leave my PC switched on all the time as well. If I need to use it for any reason it takes ages for it to start up fully so it's more convenient to just leave it all going so it's ready when I need it. If away from the PC for a day or more switch it off but I keep going back to it all day and night so it's easier for me to leave both on all the time.
Mine would blank just 2-3 seconds after power-on.
I pulled this monitor out of the garbage - someone threw it away. I found any old 12vdc power supply I had laying around (1 from an hp scaner 1250mA, another rated at 600mA) neither could supply the current (amps) required to run the backlights, therefore backlights shutdown, monitor goes blank--monitor stilled powered on, but black.
I tried all of the disassembly, re-solder various solder joints on the LCD Inverter board and removing the heat/magnetic shield from inside the back cover of the monitor. Nothing worked.
I bought a Segate 80gb external hard disk drive that came with a 12vdc power supply, looks like a typical laptop power supply, rated at 3A (3000mA). Plugged it to the monitor, it powered up, and it works flawlessly.
