lacking any photos , it be impossible to fix this talking in text box.
no?
as they say ,seeing is believing, what you call white I call black.
white on sunny beach, or black in dark room, can be the same.
PAvilion dv5-1125nr

always post what a pC does in the dark, its best.
all text seen , all logos seen (hp or compaq)
any boot screens, any log in screens.
and if the "hit F10 key to enter HP setup" is missing on said screen as seen now for 9 years running.
if that text is missing,
remove the big battery in rear of LP,they short, so get it out now
and first., do that first. always,,,
then run on AC power,
do the HP long reset? (battery out, ac pack pulled
push power button 10 to 30second, not use the ac pack only
it can run on AC forever, end ever , no problems.
do so now.
got that that 9 year old text now? in the dark, ok?
The F10 is BIOS hot key, power on and quickly hammer F10
bingo for BIOS. see that? see those screens, those are first.
if BIOS is dead, it can not boot any OS made.
BIOS does the booting job, see?

this OLD PC, is CCFL back lighted, all are.
2010 year is the magic hear we went to LED backlamps.
but your PC is 2008, see?
CCFL do these things
dim, go yellow, do dead, go intermittent and blink(strobes)
if dim, AS I SUSPECT , then its that. (brightness set to max)
CCFL tubes are 99% caused
the HV inverter is 1%

here is the tube sets.

if you tell what it does in the dark , all things
good or bad,.
answer get 10x smaller, or in fact , dead accurate.

why not just get it fixed by a tech.
all old laptops do this, EVERY SINGLE ONE.

try replacing the lcd cable

do u have a external monitor,connect it up and see whether,u r output is any better..

Have you replace the lcd inverter? if it works on external monitor, given the screen is new, then it leaves the inverter. Usually in the case of dark screen, it should be the first thing to check/replace.

If you see a dim image or flicking image on the LCD screen it means you have a backlight problem.
Connect an external monitor to the laptop and power it up, if you see a clear image on an external monitor, this means your video card is OK.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.
Check out www.lcdparts.net for parts, repair service and DIY info.

Nelia, JUst fixed one with the same problem. The lid switch is faulty - I will take a technician about 20 mins to disconnect the switch and leave it disconnected.
