Verify that it's the monitor and not the computer by hooking another monitor to the computer and observing the results. If it's your Hp f70 that is the problem, then something in it is going out, like the inverter or perhaps a loose connection. If you don't want to open the monitor and have a look-see for yourself you can always take it to a shop to have it checked out.

HP LP3065 monitor turns off and won't turn back on; is this a Windows problem


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.

HP pavilion a705W pc desktop/ on back by power plugin, green light is on, push power button to turn on, light goes out and nothing happens. I opened panels and observed light again on back lite green and...


if you have installed a new hardware, that might be the cause. specially if it is a video card. The wattage of your power supply might not be enough to run the computer. try to remove newly installed hardware such as video card. If there is none, you may try to remove the power for the hard drive and the dvd drive and check if it will turn on. Just bood in to bios..

if that works, then it definitely is the power supply. it cant provide sufficient power to your equipment..

hope that works.

regards.

How do you disassemble the hp pavilion f70 monitor? The monitor does not light up and I think it's the backlight.


plumldk1, Watch some video clips of "LCD monitor disassembly" at youtube. Yes, parting the rear cover from the front plastic bezel is the hardest thing to do!!!! Also visit www.ccl-la.com/badcaps.htm. You might see some tricks to help get the thing apart. Are you positively certain that it's the "backlight" and not the "electronic ballast" that has failed? Will you find any swollen electrolytic filter capacitors on the SMPS board? 12fixlouie

My hp pavilion f70 flat panel lcd monitor comes on and works fine with a beautiful picture...for about 1/3 of a second. then it goes blank. any ideas how i can fix this or what might be wrong?


Hi:
The symptoms you describe, pretty much diagnose a failed High Voltage power supply board problem in the monitor. This is usually cost prohibitive to repair, as LCD monitor prices have dropped a bit, so your monitor is beyond economical repair.

Screen goes black on my hp pavilion dv4000 notebook


Try connecting an external monitor to the laptop, power up the monitor first then boot up the laptop. The video data will switch to the monitor automatically, check if the monitor dislays a normal image and see if the image stays on the monitor.
Also press and hold the Fn key and press the F4 key, these keys toggle the video output between the LCD screen and the video port.
Test to see if this functions correctly.
Get back to me with the results of the tests.

HP Pavilion meets monitor


I would fathom a guess that the motherboard has been damaged, if it is the PS then you can see by taking it into a service center to have the output checked 3 v 5 v 12 volt good luck.

HP Pavilion f70 monitor has dislodged on/off button


Nor would they. If you cannot see how to open it up then U suggest the item is a snap together shell and best left alone. If it is on all the time and the wall plug inconvenient- cut the power cord[unplugged of course] and insert an inline light switch- some times called a torpedo switch. Any electrical store will have them.
