Recently, I was moving some boxes and one fell on the screen of my sister's TI-83 Plus. It has done no damage other than a small blue dot on the screen. I tried holding a pencil on the spot, then turning the screen dark as someone suggested with LCD monitor's but this hasn't helped.

In fact, the dots seem to have grown. What can I do? If you have any ideas, please let me know.

I have attached pictures of the spot.

Thanks for the help!

It looks like it may have a small crack in the LCD. Especially if it's getting worse over time and the pixels stay dark when the calc is turned off.

If it's not too old, you might be able to get it fixed under warranty, or return it to the store you bought it from as defective.
