Sold in 2006,best i can tell.
if you boot it to a linux live usb stick or CD
and it dim then its a hardware issues.
is it dim in BIOS, the brightness keys btw, work in BIOS too
even with the HDD removed. so if is dim still
then its bad CCFL or inverter .
tubes are the inverter, are you buying used parts?
why not upgrade, find a newer PC used, with windows 7 COA sticker on the bottom,.. be best.
this old pc has 0 value. if broken.
there were 2 screens used, 2 , HP P/N, get that correct.
and 1 inverter, used,
spending hard cashs $80 on a $5 bad laptop is not wise.
ever. up grade as 1st post stated. it is best.
i see the parts are rare too, even used, OUCH.
If not dIM under BIOS, you are barking up wrong tree. (asK)
get one of these. that runs (no ccFL on these its LED backlighted)

find a pc 10 years old and newer for full support and a future.
it is best advice. Windows 7 or newer..... ok?
your PC came with XP, the 3 years dead OS.
No MS support for XP
no HP support for C300 series.
rare parts.. and a square screen.
Buy a new Laptop now.

SOURCE: screen is blank
You could have a defective screen - a defective inverter or a CCFL lamp or simply the video cable needs reseating. After reseating the video cable and the problem is still there then :- To determine if you have a LCD screen or video card problem, read this and follow the instructions. Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. 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.

hi
you are absolutely right.
there are basically two connections.
any of the connector may be malfunctioning.
i ll suggest you not to open it yourself if you dont have prior experience in it.
while it wont take much to repair its not a costly affair.
if your system is under warranty it can be repaired for free.
if you find the solution helpful plz rate me carefully.
thnx
SOURCE: MONITOR ONLY HAS FAINT IMAGE, COMPUTER WORKS WITH
When you have a faint image, it means that the backlights are not turning on, most of the time, its the inverter not supplying power to the lights.
My suggestion is to take a volt meter and test the voltage going to the inverter. I can not tell you what it should be, but you should have voltage more than 5 volts going to it. Its very possible that if you changed the inverter and the screen, that the main board is not supplying enough power.
thanks adi
