I just bought a used Panasonic BT LH 2170PJ production monitor off ebay that I've been told works fine but has 2800 hours on it. I haven't received the monitor yet but this will be my first expensive monitor which I'll use for editing and on film set for camera exposure/color/ect monitoring. Is 2800 hrs. considered a lot for a monitor and is it smart for me to send it to a service center to have it checked out even if it looks ok to me? I own an inexpensive Color Munki Device for calibrate my current monitor but not really sure if that's something I should use on the Panasonic monitor when it arrives. Any suggestions?
