I lost the center screen display

My curiosity got the best of me and I may be paying the price. In anticipation for a possible radio upgrade, I removed the center stack panel today. I was very careful to gingerly disconnect all 6 harness connections on the back of the panel. When I was done examining and taking pictures, I carefully connected all connections making sure every connector clicked in place. I reinstalled the panel and lower shifter trim. When I power up the car the center screen is OFF. There is no visual indication of power to the display. I pull the out again and rechecked the connections and all appears good. Still NO screen. What did I do wrong? Is there some kind of serial data handshake that was disrupted when I removed the screen connections?

I'm at a loss

Ebay is ur friend!

I've had this touchscreen pulled out of my Gen1 about a half-dozen times w/o issue so you may just want to re-check those connections and fuses one last time.

Good thing the touchscreen isn't critical to the operation on your Volt and it would still be driveable even if removed completely!;)

Is there a fuse for just the screen? I have audio the XM is still playing fine. Just a black (no power) screen.

Keep in mind your touchscreen should never be completely black when your Gen1 is turned on.
When working properly, you should still be able to see the faint glow of the backlight of the touchscreen even if you command the screen off using the voice command 'display off'...

I only disconnected required center stack connections and set it aside to take photos of visible component info labels for future reference.

The 8 pin black connection appears have the power supply feeds and signal wire. I'm not sure what the blue connector does. I can't find information about it. I'm guessing it's a data connection.

Besides the power/ground connection, the other connector for the touchscreen terminates into the radio module.

Stupid question but did you also happen to disconnect any connectors from the radio module? If so, you may want to re-check the radio connectors as well since missing this connection on the radio would give the same symptom as not having the touchscreen connected.

Good luck on getting this issue sorted!;)

Glad to hear this relatively inexpensive touchscreen replacement did the trick!:cool:
