820-02016-A "no image" chimes and pulls normal power.

[KC Micro Tronix]

Display was damaged and replaced before it was sent to me. Machine chimes but no image or back light. No external video.
I tried a new display to make sure. Did not see any shorts on the display data lines.

What the client said?
There was partial image and backlight, before screen replaced?
I suppose damage induced because of wrong manipulation.

Just chimes, no USB activity?
