HP Pavilion - the monitor flashes off and on

On start-up, the screen flashes off and on every few seconds, then after about 2 hours suddenly starts working. When I say flashes off and on I mean the screen is black, and then for a millisecond the desktop picture will appear and then it goes black again.

    When I start up my computer it goes black and I have to mash the monitor power button to get it to come back up. It stays up for about 2 seconds and then goes black again. I do this repeatedly until finally it just stays up... by repeatedly I mean approximately 50+ times. Very frustrating. What can I do to fix this problem?

    Mine will come on normally for a second or so, then goes blank. Turning it off/on just repeats the problem. I'm hoping for a solution I can perform myself.

    I have HP Pavilion notebook - it is back at HP AGAIN, second time after over 12 hours on phone with technical support, exact same problem, they can't fix it, don't know what to do. Just purchased it $1200 in Feb 08, very frustrating.

    My screen will flash for hours on end.. My monitor just came on after 2 days of flashing.. I'm shopping for a new monitor unless there is something I can do to fix this issue myself. Thanks

Pls uninstall the video card drivers and reinstall them.

Also pls look for any graphics driver updates from the manufacturer.

Also pls check if the cable from the power supply for the graphics is connected on the motherboard.

Pls check with another monitor if it is doing the same thing.
If the same happens with another monitor, then it is an issue with the video card..

HP Pavilion F1503 only displays a split second?


well, its a 2003 LDC 13 years old ,
its bad
the monitor itself of the power pack to it is bad.
you can test it on any PC< or laptop made
if its dead on all , then its dead.
what more needs saying,
older LCD monitors had old CCFL, lamps. that love to fail
newer are LED back lights that last for ever. it seems
so up grade?
seems your back light is dead
ever do the flash light trick
shine it at the dead screen see good data
yes, then the CCFL is DEAD< (or its power supply ,deep inside)
fixed may but would never do a 2003, not now.
lots of used good LED for sale,

Volume screen keeps popping up every few seconds, when I touch "menu" button it goes away, only to come back a few seconds later


michaelfoder, Because very strange things start to appear on the screens of cold cathode fluorescent lamp, back-lit, LCD monitors, I always investigate the "switch-mode-power-supply/ccfl inverter supply for very common occuring defects in the supply!!! You can find out about them here: http://www.lesliewong.us/blog/2005/05/02/hp-pavilion-f1703-flat-panel-display-blackout-solution/ Just remember to do a fixya rating and testimonial if this response helps you to find and correct problem in your 2-3year old unit. Problem could be an unstable +5v or +3.3v dc supply rail. 12fixlouie

Hp pavilion f1703 flashes on and off. Tried pushing F8 for 30 seconds - no result.


have you checked the power connecter at the back of the monitor?

is it the whole PC that is flashing on and off or JUSTr the monitor?

the F8 key when turning on a Windows based PC, will only take you to a screen to choose how to start windows, in Normal mode, safe mode, or commandline mode.

none of this helps a flickering screen.

try and change out the data cable (VGA cable, blue screw in plug) and the power cable if possible.

Problem with HP laptop - starting on for a second and then dying


Try reseating the Processor, and checking all the connections on the inside again, also try switching the RAM around such as trying only one RAM stick, one in each slot, if you only have one RAM stick try different compatible RAM.

HP Pavilion f1703 screen goes suddenly black


After reading a number of posts regarding this problem, I disconnected the speaker from the screen electric outlet meant for this purpose, thinking it may have been pulling a bit too much amperage to the detriment of the screen. I am going to hook a small transformer to feed the speakers directly thereby bypassing the electric feed from the screen itself. Hope it continues to work. I will let you know if it doesn't.

HP Pavilion 17" screen flashes on and off


Try reinstalling your monitor. You should have a disc that came with all of your equipment.Make sure it is a clean install and there are no other programs running. Also check all connections to make sure they are tight.

If this does not help, do you have another monitor you can install temporarily so that you can work on this problem?

Is this a new monitor installation? You might want to check your hardware compatibility list which you will find under Start>Programs>accessories>compatibility wizard.

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.
