Need help - Black Panel Displays after patch 1.9.3

Hi!
Need some help. After installing patch 1.9.3 the electronic displays on various aircraft panels are all black as seen in the screenshot below.
Before patch 1.8.3 I changed the original BaseInstrument file (refresh rate mod), but had no problem after the fist patch was installed. The problem only came after installing the Japan Patch. Anybody have any idea what to do other than reinstalling the whole sim? I have not changed the nvidia driver since the first msfs install.

I would appreciate very much if someone could help me.

Sigh…try searching first
