# TSG: Pen display doesn't show anything

## **NO SIGNAL**

If you turn on your pen display and see a NO SIGNAL message, then this is a different kind of problem. Instead go here: [TSG: Pen display shows NO SIGNAL message](/drawtab/troubleshoot/tsg-no-signal.md)

## Ensure your computer actually detects the display

Does your computer detect the display in the tablet? Check your operating system's display settings. More here: [TSG: computer does not detect display](/drawtab/troubleshoot/tsg-display-detection.md)

## Check if the backlight is broken

If your computer does detect the display, but you still see just a back screen, shine a flashlight at your tablet's screen, and see if you can detect faint traces of the image your computer is sending. If you do see something, then this means the backlight is broken.

Unfortunately this is not an easy or cheap thing to repair. Most people simply get a new tablet, or if it is under warranty, have the tablet replaced.

## Check if the display works with another source of display signal

For example, connect it to another computer or X-BOX or DVD player. If you see something, then it tells you that the pen display is capable of showing something but that the problem is somewhere else.
