I'm afraid you replaced the whole screen when all you needed to do was replace the inverter, which is much simpler to do. Virtually all LCD screens light up with an inverter. Usually, they just go blank blue, though; I'm puzzled about the "dim" manifestation. Call IBM help--they have foreign accents, but are usually quite knowledgable.

I had the same problem, and managed to fix it my replacing the whole screen (inc. laptop lid) from another broken model. It's not for the fainthearted I'm afraid.
I since discovered, the problem (if you can see the display, but it is very faint), the problem could be the screen inverter which can be replaced without removing the screen from the laptop chassis. (there are a few guides available on the internet to do this) I've seen a few of these items on ebay for not a lot of money (£10/$20), and changing it should be much easier.However it could also be the backlight itself as well.
google "Laptop Repair Help Screen inverter replacement" to get an idea of this problem , and possible solutions

If you want to do what I did(good luck!!!) you have to take quite a lot of the machine apart.
1) Close laptop and lay it down on it's lid(bottom facing upwards).
2) Remove battery.
3) Remove EVERY screw you can see on the underside (even the one that holds the cmos battery(as I think it doubles as an anchor for the keyboard). Most are small crosshead, but you may need a flat top for one or two.
There are also 'hidden' screws - on the front edge(3 I think) and either side of the back (where the usb/video ports are)(2). The panels that hide these look like little plastic square blanking plates. These just pry off(they are just stuck on, the screws are behind them) I would hold off removing the ones off the back (4 screws) for the moment as these attach the screen to the chassis
4) Once all screws removed, turn laptop over and open it up. You should now be able to prise off the keyboard (use a small screwdriver or knife to get under the keyboard, it is held by a connector towards the centre but, should pop off provided the screw from the underside is removed.
5) Once keyboard is off, there is one screw to remove, which holds the screen to the motherboard, and one or two others securing the rest of the keyboard surround.
6) Remove the keyboard surround, and you should be able to see the anchor points in the left and right corners of the laptop chassis (under the screen).
You should then be able to remove the last 4 screws from the back of the case (the hidden ones). Screen should lift off. Then do the opposite to put lid back on.

How to remove the display on IBM T21 laptop

The laptop screen is secured to the laptop with screws at the hinges.
There are usually two screws per hinge. The LCD screen has one ribbon cable and possibly a power connector for the back lighting attached to the motherboard near the hinges. Disconnect these before you lift the LCD off the base, they are under the plastic panel above the function keys next to the hinges.

I had a similar problem after My pc got damp in a bag in the rain. I contacted IBM and was given this fix which I am supprised worked but it did so here it is cannot hurt to try. Remove the main battery and the mains power supply press the power on button for 17 seconds. This I think is to drain all the power from the laptop altogether. Replace the mains lead and turn on. Once the laptop has openen up into windows turn it off and replace the mains battery then power on again. In my case this worked I hope this helps.

Need urgent help : staring problem with my IBM T21

Are you saying that it takes pressing the power button a number of times before it will start up? If there are no LEDs on (other than the power LED on the external A/C power adaptor) until pressing the power on button finally works then I suspect your power switch is defective. The only way to fix that is disassembly and replacement. Replacing the switch isn?t too hard however unless you have the tools, time and some experience you might want to consider taking it down to the local repair shop. If you have any more questions let us know and please don?t forget to rate this posting.
