Hi
old PC
when did it last run perfectly last week last year, never, I found it in dumpster. or garage sale for $1
swap, (exchanged)
the screen never ever shows text. right? = equals no activity>?
this old PC is CCFL pC, back lighted.
and as such those fail easy, (20,000 hr rated max)
we use LED now, and never fail.
the tests are here
laptop, PC, NX old series. from long ago.
all are problematic this old,
But screen dead is #1 for sure. 100% dead.
btw that lamp can turn on then off, the flicker go dim or just be pure intermittant folly;, a PITA they are and the inverter same.
see the simple tests here.

first every LT made take it out first
then try. 15 year old batteries short.
2003 is oldest one i see.
so only 14 years old. yes old

there is someting loose inside the computer so you may have to open it and check for loose conections or pices that they may be loose or video conectors
SOURCE: i have any chance to reset on power password?
Remove the Battery
Remove the Hard Disk
Remove the DIMM Memory from underneath the Laptop and remove the 2x KEYBOARD screws
Turnover laptop and REMOVE the KEYBOARD by pushing back the 4 x Spring clips between keys "esc" & "F1" - "F4" & "F5" - "F8" & "F9" - "F12" & "DELETE"
Remove the 2nd DIMM Memory and Unclip the Battery from Mainboard.
Leave for 30 minutes then start with mains ONLY no battery or Hard Disk
BIOS NOW RESET including Password
Switch Off and now put all back together

At the risk of subjecting myself to your possible wrath, I suggest you replace the motherboard. I don't know your computer repair prowess, and am not doubting it for a minute, but I 'stand' here to tell you, that it's just not that simple.
The hardware components are installed down into a bare motherboard. The leads for the hardware components are in their 'raw' state, where they hang down past the motherboard. Then the motherboard is heated up using a hot air soldering method, and the solder flows over the leads making a precise, pretty little solder joint. This is done with robotics. Once this is accomplished, the extra length of lead is snipped off.
Some components are installed by hand. Very few of them. The operator uses a soldering station, and an instrument that magnifies the area by a great amount. Looks like a binocular microscope. One, two ,three, and the next motherboard comes up, and the same part, by the same operator is installed once more.
Again, not doubting your expertise in this area, but if you have use much heat, or linger too long, you stand the chance of making the copper circuit trace, lift right off of the motherboard, when you go to remove a component. Not enough heat, and you can't remove enough solder, nor get the lead to come out of the hole. (I use solder wick. Also known as Desoldering Braid. Solder ****** tools are for the bird's! (Desoldering Tool)
Same thing with soldering a new component in place. Too much heat or linger too long,....well you know what happens. Not enough heat, or staying in position long enough, plus using the right technique, you get a cold solder joint. It's a lot of fun, when you reassemble the laptop all the way, and find this! Guess what happens next? Yep! Do it all over again!
I'm not a saleman for Ebay, but I find a lot of my motherboards for laptops on there. I would also suggest looking at -> Laptops for Parts.
