Screen goes black

no boot M9510f,
no boot is like the all time #1 complaint on PCs.
endless posts online on this and for sure at HP.. ever read their forums?
there real name is (and is supported still at HP) is
HP Pavilion Elite m9510f Desktop PC
no statement on screens, is the screen dead, and black
never once see HP logo, never see words to the effect
hit ESC to enter HP setup (BIOS) or F1 or F10 or????? do tell please.
that is first, forget windows now (its LAST)
screen model or maker stated ,
my guess a flat screen LCD
and the front button on it works and the screens local OSD menu works, right?
if PC is dead, the screen is checked first. for sure if BIOS screens in the PC are 100% dead, no text no F1,ESC,F10 keys prompted in text means PC dead or SCREEN dead.


here is HP page on your pc

here is black screen tests.
the screen (DISPLAY monitor) has its own brain
and is called OSD, on screen display
we check that first. always........ if screen is made before 2000 year
we trash it.... LOL (before first brains inside )

Again install the operating system

A flickering screen with pink colour is a sign of a CCFL lamp problem.
The CCFL lamp is a mini fluro tube and it provides the back-lighting, it is definitely faulty and about to fail completely.
You need to get it repaired while it is still under warranty.

Hello,

Yes, The pink tint is an indication that the backlight is failing. Now the backlight is basically dead, the best way to get back going is to do an Ebay search for your model laptop and get a new screen. Most screens can be purchased for around $50.00 - $70.00 and they are very easy to swap. Email me if you need more info.

It Might be the video cable.

Pls ask your dealer about the warranty..It depends as per the market.. If the light is comming then replace the AD card other wise The problem with the inverter card.. replace ...

we have here , like 1000s of black screens posted here now.
all the same all with CCFL lamps. that die. same solution.
older monitors have a power saver mode inside it,
push the front button called menu, then see OSD menu
then find and turn off power saver.
if the OSD fails to show up; the CCFL are dead.
this monitor was made in 2007, and 2010 is the starting year
for ending the usage of CCFL (starting on large screens working to small)

im reading your manual for you now, free.
page 4 tells you it has CCFT (T mean Tube, L means lamp)
same same.

for free. here. the site on the internet in this regard.

all old HP monitors are made for old PC 2000 year.
your PC is not 17 years old i bet.
so all this old saver stuff is now WRONG.
(all this is old school Energy Star , malarkey, )

Yes. seen better days. Get a new one. 

plug in a different monitor temporarily, check your display settings (right click background, settings, advanced, monitor) and set refresh rate to 60hz. plug in this monitor again and see if that helps some monitors (lcd's especially) cannot handle beyond 60hz

Monitor is dead. The LCD inverter board probably went out and needs replacing. More than likely, it will cost you over $100 to get it fixed. It's better to spend the money on a new monitor.
