    Hello,
    I replaced the speakers in my 7450. Now I have no laptop display screen. I can view it on my TV through the HDMI. Initially, I had no screen and no touch pad. I removed the CMOS battery and got the touch pad back. I have checked and rechecked all of my connections. I didn't mess with any of the display components that I know of. I checked the connections anyway and re seated my display connector. The BIOS states "unknown panel" and native resolution is 291 x 113. Could someone offer some help?

    Thank you

    edit: I should note I have integrated graphics and I'm posting this on the device in question.

    edit2: I just realized I should have posted this in the Latitude subsection
