Screen toast after only 2 years?

---

So my Simple Touch Reader is about 2 years old and I'm pretty sure the screen is already toast (or almost toast) . I have to swipe tons of times to unlock it, and when I actually can unlock it, swipe to turn page almost never works...I have to use the buttons. It's like my Nook's screen has lost all sensitivity.

After only 2 years it's pretty disappointing.

Any ideas on what might be the problem...and how to fix it?

Thanks.

Clean the screen.
The IR sensors are sensitive to any crud that may have collected.
Use a lightly damp Q-Tip to clean the inside of the bezel.

It would be interesting if I could see that Nook now.
When there is no finger on the screen only a single IR LED pulses in a slow fashion.
Once a finger hits the screen, this low power mode detects it and switches
to the full left side and bottom side IR LED scanning mode.
Using my IR detector diode method you can hear exactly what is going on.

I'll try giving it a good cleaning. I can't remember the last time I wiped it down...
