Here is some of the alignment info:
The following is an example of what could be displayed on screen and an
explanation of the characters shown.
GR3 AM1 PRTM C2
6 C 11 23
Top Line
GR3A = Control System
C = Consumer, M = Motel, H = Hospital
1 = 1st Version of the software
PRTM = Error Codes
P = PIP, R = Remote Locator, T = Tuner, M = Memory
If a letter appears it indicates a failed communication or the set does not
have these features. These codes can be useful in troubleshooting the
control system.
C2 = Closed Captioning feature
Pressing the A/CH Button on the Remote will cause the display to cycle
through the Closed Caption modes.
Note: Pressing the Status Button on the Transmitter will toggle the
Information Display (GR3A-Code and Type-Error Codes) on and off.
Bottom Line
6 = Channel Number
C = Test Mode
11 = Register Number
23 = Register Value in Hex
The Channel Up/Down Buttons on the Remote Transmitter will access the
channel tuned.
Registers can be access through the Menu's Up and Down Buttons on the
Remote.
Register Values can be changed by pressing the Menu's Left/- or Right/+
Buttons on the transmitter.
Shown below is a list of the registers available on the deluxe
microprocessor with 16k ROM.

Note: To access the PIP service mode while in the "C" service mode, press
the PIP "ON" Button. PIP will appear on the screen. the test mode display
will change the register number digit by changing the first digit to a 3_
indicating the PIP adjustment mode. Pressing the Left/- or Right/+ buttons
will now adjust the position of the PIP in the Horizontal direction. This
is the only setup adjustment required for PIP.
To save a register: While still in test mode "C" turn the power "OFF" at the
television set keyboard.
Note: Exiting with the power button on the remote transmitter will not save
any changes made in the service mode.

> See if this might be the case:
>
> 1. Enter the Service Mode (06-25-96 Menu)
> 2. Use the Menu to cycle to Test Mode "C".
> 3. Exit the Service Mode at the set's keyboard.
> Note: The reason for no OSD is the set has slipped into Test Mode "D".
