About 3 weeks ago I stupidly brushed off some sand residue of the manufacturing of automotive monoblocks, so I used a piece of large paper, like the one you use to dry your hands at a WC.

I tried to dust off the sand particles off my LCD screen with that paper, only to realize a week later horrified that I've scratched the LCD in several parts of my T42p display.

I've read about toothpaste method, Vaseline method, Brasso method, but I'm wondering if any of you actually fixed or at least made the scratches not to visible. If I touch the screen I do not feel the scratch to be deep, but when the LCD is off I can see the horrible horizontal and vertical scratches.

Suggestions?

Something I discovered out of desperation on an HDTV I acquired because of a HUGE scratch down the left side...

Like yours, scratches were visible, but could not be felt with a bare fingertip gently crossing the scratch. I used an alcohol wipe in a circular motion to clean it, then experimented. I ended up grabbing some of the congealed glop that is always on the edge of the fabric softner bottle and massaging it into the scratch. To my surprise, it dissapeared almost entirely. If the angle is right and the screen is off, it's just visible. Prior to my little experiment, it was WHITE when the screen was off, and BLACK on a white background.

Let us know if this works on yours.

BTW: Gooey glop, not crusty. I used a bit from the threads on the bottle. It wasn't liquid by any means, but wasn't scabbed over either.

I don't understand the gooey glop part, anyhow I screw a part of the screen, I was cleaning some dirt dots of sand with a shirt and a knife, I accidently SCRATCHED the lcd on the left side just where the LCD is attached to the bezel. I used brasso but now I have a big shine and irregular surface glaring. I'm sad.

I have found that wax (i.e., candle) works pretty well.

Just rub it across the scratch, then wipe off in circular motions with a soft cloth.

does it work even when you have eroded quite badly the lcd so that when the laptop is on the area where I put Brasso is shining, like when you put water on the LCD.

I'm pretty sure that wax is not permanent. Ultimately, you can clean it off with more wiping/LCD cleaner. I'd give it a shot.

I used the semi-clotted gunk that ends up on the threaded part of the fabric softener bottle.
That was almost 6 months ago, and I have yet to do anything but wipe dust off the surface.

The consistency was similar to chapstick.

Worked great!

I have tried to remove marks from the mouse buttons above the touchpad on a few T4x machines and have come to the conclusion that it can’t be done perfectly.

My first attempt used a plastic scratch remover available at an automotive store. This actually worked, but it removed the matte finish from one area, leaving a buffed spot. So, I tried it on the entire screen. Then I ended up with directional marks from the direction I was polishing. Also, I could not get close to the edges.
Next, I tried removing the entire LCD panel, taping it to my workbench, covering the metallic tape, and buffed the entire screen in the same direction. This left a screen that was too glossy, and showed a glare from reflections of windows in the room. Next I tired wet polishing with ultra-fine mesh wet sandpaper – 2000 grit. This is made specifically for polishing a soft finish. This restored the matte appearance to the entire screen. I cleaned all residue from the polishing and replaced the screen in the lid assembly.

To my surprise, the screen looked really bad when I started the computer. The polishing action resulted in several pressure marks – white shadows that always show on the screen.

I found that it is extremely easy to put pressure marks in a LCD panel when attempting to polish scratches or marks out of it.

So now I stay away from any machines with LCDs that have noticeable scratches from keyboard marks.

Great point. It reminds of the adage "tight is tight and too tight is broken". I occasionally have to relearn this with palmrest screws

I have left the Thinkpad that state, the thing I'd like to try is to see if I can return to the matte finish on the part that is heavily buffed where I the knife scratch were.

I still don't know if I should replace the screen with a new one (since this laptop goes to industrial factories with lots of smoke and sand, so I think it wouldn't be worth spending more money) but if I 'retire' this laptop from work I could restore it. But I'd like a new T61p.

Is there a kit from IBM, or elsewere where one can obtain some of those M2.5 × 4.8 mm vinyl tipped screws. I see they're offered along with say another part (dock top) but that's overkill, just need the screws.

Thanks!

Here are the pics of my 'scratched' LCD, that area that seems shiny is a result of me putting too much Brasso, any suggestions on how to even the surface to have the same matte finish:
