Thanks for the suggestion. You are correct, it is a TI, not TI2. I'm confident i found the "contrast" setting using your suggestions. I found the CPU Lux parameter - turning knob 1, i could adjust the brightness of the LEDs. Hitting parameter one more time to the left should have LCD contrast on knob 1. Unfortunately it didn't do anything. I am pretty sure the LCD is faulty now.
From reference manual:
0 to 127: Brightness of all LEDs.
BPM LED Brightness
0% to 100%: Relative brightness of the BPM LED.
Specifies what the multi purpose BPM/LFO LED will indicate.
0 to 127: Optimize the display for different viewing angles.
