The IN START service menu

Access this menu via either MENU on the set and remote (not all
firmware versions), sending the code via a universal remote or
via the serial port.  See the EZ-Adjust menu for details.

Displays a large menu covering most of the display.  The left
column shows some stats at the top and a menu below.  To the right
is the available options for the selected menu item.

The example below is from my set, yours will probably vary a little.
Drop a note if you have different items, especially if you can figure
out what they do.

The top left section:

     IN START
Model Name : 32LF11-UA
S/W Version : V04.23.00
UTT : 7
UI Res. Version: V00.01
BOOT Version: V00.01

SPI Boot version : V03.00.00
LED Version : V00
EDID Version (RGB) : V01.01
EDID Version (HDMI) : V01.02

UTT seems to be a odometer to track run time in hours.  There is an
option below to reset it, guess when they do a 'factory reconditioned'
unit or perhaps when the backlight is changed the counter is supposed
to be cleared.

BOOT Version is probably the U-Boot version but obviously an internal
to LG versioning.

SPI Boot is probably what runs first and sets up the RAM and figures
out what part of the main Flash to load and execute.

Not sure what the LED version is all about since the power LED/remote
sensor board doesn't appear to have a microcontroller.  Probably refers
to the firmware that gets loaded into the MICOM/8051 micro.  It seems to
do a lot more than just run the LEDs though.


The Menu items

Items with a - in front of the number appear to be informational only
since when you press the right arrow to enter the menu these items
are greyed out.

1. Adjust Check		-0.  Adjust ADC[480i Comp]	OK
			-1.  Adjust ADC[1080p Comp]	OK
			-2.  Adjust ADC[RGB]		OK
			-3.  Adjust WhiteBalance	OK
			-4.  Debug Print Mode		Off
			 5.  Tool Option 1		17792
			 6.  Tool Option 2		2600
			 7.  Tool Option 3		416
			 8.  Tool Option 4		1152
			-9.  EDID RGB			OK (0x36)
			-10. EDID HDMI1			OK (0x1D,0xCA)
			-11. EDID HDMI2			OK (0x1D,0xBA)
			-12. EDID HDMI3			OK (0x1D,0xAA)

The only items lit are the tool options.  The numbers have arrows to
the side but you can't actually adjust them from here.  You can do so
from the EZ-Adjust Menu and you don't have to futz with binary bit
fields either so go there instead.

2. ADC Data		0. Source			480i/Comp 1080p/RGB

			480i		Comp 1080p	RGB
    1. Save to NVRAM	On		On		On
    2. Red   Offset	7F		81		93
    3. Green Offset	7F		62		7D
    4. Blue  Offset	7F		80		86
    5. Red   Gain	48		BF		71
    6. Green Gain	49		C5		73
    7. Blue  Gain	4B		BF		72
    8. Reset		ON		ON		ON

Without calibration test equipment these are best left alone.

			17. UTT Reset			Reset

No idea what the Analogue System options are.

Baudrate cen be picked from 2400 to 460800.  9600 is the default but
115200 matches U-Boot and eliminates having to change your terminal
program.

The two hour off option should instantly be switched off.  This causes
the set to turn itself off after two hours of 'inactivity', i.e. no
key presses on the set or remote.  Has to be the greens at work.
Good grief, many configurations would only send IR to the TV to turn
it on and off for a good portion of it's service.  Officially the
two hour limit only hits for the timed power on but it bit me while
playing one of the cable music channels with the display switched
completely off from the eco menu,  But only once.

Audio EQ does what?  If I had to guess it sets up a default EQ 
that tries to compensate for the tiny speakers blowing out the
bottom.  At least the specs for the NTC3100 say it CAN load a profile
to compensate for the speakers.  Feh, just take the Optical out to an
amp driving real speakers, K?

The 15 min timer turns the set off after fifteen minutes without a
signal.

No real clue what the next couple do.

Tuner Option defaults to Enhanced Ghost but can select between
Enhanced Phase High, Default and Enhanced Phase. And exactly what they
do is also a mystery.  Pretty sure they only apply to ATSC/DVB-T though.

Atten Signal probably engages a small attenuator to cope with
overload on the RF jack.

5.  Test Option		0.  Auto Test			Off
			1.  UI Time Out			On
			2.  Store Mode Test		Off

6.  External ADC	External ADC

			Comp 480i
			Comp 1080p
			RGB

7. Spread Spectrum	1.  SSC EN			Enable
			2.  Percent(%)			1
			3.  Period(KHz)			25

This looks like the same thing on a lot of PC motherboards.  By
jittering the system clocks a bit it reduces the spikes on the
Spectrum Analyzer of the emissions from the system board, making
it easier to get FCC type certification.

8. Sync Level		1.  Comp. 1080			6
			2.  Comp. 720			4
			3.  Comp. 480			3

TV Link-Loader
	Some sets show a menu allowing load/save via USB.  Mine doesn't.
	Think it may be expecting something via serial.
	?  Load up for Hotel Mode?  Load Channel lists?
	Online references to a box from LG that hooks up to the
	serial port called a TV Link Loader.
