# Common problems

**Problems all drawing tablets can have**

* They lose or damage their pen. Replacement pens are **expensive**. A replacement may cost a significant fraction of what you paid for the tablet.
* The pen no longer reports pressure
* The pen pressure is stuck at 100%.
* [TSG: Tablet driver does not detect tablet](/drawtab/troubleshoot/tsg-tablet-driver-does-not-detect-tablet.md).
* The tablet driver cannot detect the pen.

**Problems unique to pen displays**

* The pen display doesn't show anything.
* [TSG: Pen display shows NO SIGNAL message](/drawtab/troubleshoot/tsg-no-signal.md).

I have put together a list of troubleshooting articles to help with these problems and many others. More here: [Troubleshooting](/drawtab/troubleshoot.md)
