I run a small repair business in Michigan. I had a customer with a bad LCD panel on a Dell laptop.

I have replaced over 20 of these panels in the past. I purchased a new, generic panel from ebAY which is compatible with the Dell LCD panel. The connectors all fit and it's the right size to fill the bezel. I hope it's truly compatible.

When I power on the laptop, the screen immediatley brightens up but no graphics, text, or anything appear on the screen. I checked and re-checked the flat ribbion cable connection and it's secure. I assume the inverter is working as the panel does light up.

Any thoughts?

My first suspicion would be that the new panel is simply faulty.

What was the fault with the original panel? Could you still see that the video drive to the LCD was OK?

Try plugging into an external monitor and see if it's blank as well.
