Please do not use all capital letters, it's like shouting.

If the screen is not showing anything at all from the moment you turn it on, it has nothing to do with the brightness setting.

Go right close up to the screen. If you can see a faint image, the screen just needs a new backlight.

If you cannot see even a faint image, your laptop needs a new screen.

Plug in an external monitor.
Does that work? If yes, it's likely you need a new screen.

If no; maybe a graphics problem with the laptop. Often a case for scrapping it.

HI Gunvant,

for queries such as yours, you should always provide the make and full model number of the device concerned.

Peet - is just plugging in an external monitor ok for it to work, I thought (depending on model) sometimes there is a key to press to select between external and original.

Good Luck - Keep us posted

Hi Mike.
I didn't want to make it too complicated, as unsure if this thread is going anywhere.

You are of course correct. However, I usually find an external monitor displays automatically.
I should, have mentioned that it may be necessary to use the function Key (Fn) in conjunction with one of the 'F' keys which has a symbol representing a screen.

If an external monitor works then there are several possibilities. One of these is the cable which connects the computer to the screen (it can fail at the screen hinge) or a loose connector either end.

Just for info you mean "computer" not CPU. A CPU is a microchip, see here:

That's an old computer and I can only suggest using Google. Anything we find is likely to be outside India and it is not something anyone on the forum is likely to know.

Keep watching though, just in case I'm wrong and someone else has some ideas.

Always pop back and let us know the outcome - thanks

That's not just old ; it's ancient.
The only way you'll find the components you need is to find an identical model with usable parts.

Even if you do find replacement components:
1. Are you sure it's the backlight?
The backlight itself is built into the LED display screen. It's not usual to replace
the backlight.
You have to replace the entire screen.
And not just any old backlight will do. It has to be the exact type for that screen.

2. If it's not a screen/backlight problem, it could be the inverter driving it.
Again, it's likely this would have to be sourced from a scrap PC.
You would need to be certain it was exactly the same inverter, for your particular
model.

3. If the fault lies with neither of the above, it could
be a graphics chip problem on the motherboard.
(Unless an external monitor proved it to be ok).
Again - you'd have to source it from an identical,
scrapped laptop.

Unless you are a keen vintage PC collector/hobbyist/enthusiast, it's probably not worth the time, effort or money to get a laptop this age up and running.

As Derek suggested; Use Google You may be lucky.
