Screen backlight is probably failing, the fact that you are getting an image suggests that the inverter is ok (although replacement is often the only way of telling).

Firstly, plug the laptop into an external monitor, if the picture is clear, this will confirm that the issue lies with the backlight or the inverter, if however it does not, then you may have issues with the onboard graphics chip beginning to fail (expensive as it will need a new motherboard).

The only other cause can be a damaged VGA lead (unlikely).

Best guess would be that the laptop screen needs replacing, as replacing the tube for the backlight is a very difficult task and not really worth the effort or expense. You can find some good 2nd hand screens now for a 15.4 laptop quite cheaply and replacement is very easy

Compaq Presario f700 NOTEBOOK.
first off im amazed it can even blink bark or glow at all
laptop are scaled in DOG YEARs.
my first guess is the not tried yet, exernal VGA jack works
so only your screen is bad.
as all are now with CCFL lamps dead or its power pack.
called "inverter"
the lamps go dim, yellow ,flicker then die, all do if CCFL
best is upgrade top LED laptop and w7 and newer OS.
the BIOS pages must work or the screen is bad
seems power is ok, to me. and you.
it came with VISTA.
year 2007?
im reading your service manual now.
and see this?


that is CCFL lamp not LED>
this is bad or the inverter card that drives is is bad if BIOS FAILs
to show in the screen, My best guess, no tests by me,
testing is the only sure way to fix problems not guessing.
why not get tech to fix it?

no photos, no joy
why post lacking the look, as your topic is all 100% Look.

a 2007 note book
the year or close to the year they made Nivida chip solderball , GPUs, that all fail.
so if its got that its, doomed, and buy 3 more used mobo
and all doomed sure

the screen is just a LCD screen and a backlight
if the digital data to it is bad (GPU) then the GPU is bad.
and hits soldered down,,,
buy desktop next time, and its child's play fix.
pop a new card
or and HP 9540w, that has cards !@!! and dont FAIL.

When i open the lid of my presario F700 it does not automatically show the screen. I have to move the lid over and over and over again to different points to get the screen to show.


In this regard there is something happen on the video card cable underneath on the hinge of the laptop. I have also Presario laptop that has same issue that you encountered.If you can able to open the laptop's hinge to check the video cable connection then you can check on it by resetting the connnection though. If your not able to do so either to go in the computer shop or have to call HP/Compaq for assistance. Thank you.

Sounds like the power converter. The power input and the battery are single voltage. The computer requires multiple voltages which are generated by a power converter. If you have installed this motherboard, ensure the connections to the power converter are correct.

Blank (dark) screen


If you can still see a faint image on the screen, then its the inverter coil or the inverter itself which has gone bad or maybe even worked itself loose causing a bad connection.
Either way you will have to take it to PC repair shop to be looked at.

Good luck and thanks for using Fixya!
