TLA7012 Black Screen

I have a TLA7012 and when I power the unit on, it goes into a black screen. Do you haec any ideas on how to troubleshoot this?

The TLA7012 went out of production in 2014. At this point our service group provide best effort repair and replacement parts are limited. Below I'll provide information for the service group. They can issue a repair quote if you want us to look at the instrument.

Hi,

Replace the MB Battery and then change the BIOS Settings (Configuration/Video Configuration) in Enabling Local Flat Panel (LFP) and Save New Settings.

Succes,
