PLEASE IGNORE.  I fixed it. Turns out speaker cable inside monitor was lose, I just assumed if it came new from the factory it would be okay.. must have gotten lose from shipping...

 

I just replaced the LCD on my XPS m1210. I replaced the entire unit - LCD, LCD cover and front bezel trim with new Dell part (it arrived all in one piece).

Install was fine.. but now there is NO SOUND coming from the speakers on the screen. If I plug in my headphones there is sound.

I've checked the sound configuration and it said there was no problem and the device is working properly.

Can anyone help me please?
