I posted this in the
General Samsung HLP Issues & Questions (Post all here) thread yesterday. Maybe it will come in handy here.

Can one idiot protect other idiots?

Here are the "enter-SM" instructions for the HLN sets. They are the same for a HLP set but the contents of the SM and navigation keys are different. I haven't checked all the navigation instructions myself.
Find Samsung Firmware Version:
The firmware version installed on any set is recorded on the first page of the SM. There is a long ID number at the bottom of the page. The last three digits (HLN) or last four digits (HLP) are the firmware version of your set.
Remember that in any dealing with Samsung you are not supposed to know your firmware version.
Record your User Settings for "Picture" before you enter the SM. The HLP sets will revert to factory defaults for the UM when you exit the SM.
Instructions for accessing the Samsung Service Menu:
Anyone using these suggestions should know that the only change I have ever made to the SM is changing GAMMA from the default value to zero. I have never "messed around" in the SM. Remember that there is no reset function. If you see something that looks like one don't use it.
I can recommend, without any reservations, recording all original SM settings before making additional changes.

Turn Melody off in the user menu (allows entering the Service Menu from power On state without using a lamp cycle).
With the set ON, press Power-Mute-1-8-2-Power in quick succession.
(If the set is already off, just do Mute-1-8-2-Power )
The service menu should appear for the input you were viewing before keying the above sequence. Be sure to give the set enough time to complete the process(30-60 seconds).
While in the service menu, you can change inputs with the TV/Video button to view the SM for other modes.
Use the CH up, CH down & select keys to navigate the Service Menu. Press MENU to return to the main Service Menu after viewing individual functions.
Later, you will use the VOL(+) & VOL(-) keys to change the SM values.
" ... when you access the SM on the HLPxx63 (probably all HLP models), the directional arrows around the "Enter" button control navigation, not the volume and channel buttons ..." MacGyver1970.
To Exit the SM, power off. Leave it off for several(30) seconds. (until all cooling activity is complete)
Example steps to change GAMMA on a HLP5063 with firmware version 1011 and a build date of May 2004:
The SM main menu looks like this.
1. DDP1011 (The GAMMA setting is here.)
2. GM1601
3. DNIe
4. FLI2310
5. CXA2171
6. Vsp9437
7. Upd 64083
8. CCA
9. SP Actuator
10. OPTION (The tally of hours of lamp operation is in this menu.)
Ver: T_ATLNUS_1011 (this is the firmware version)
First record user menu entries for "picture" and enter SM.
Steps from the main SM.
1. Select DDP1011 using the directional arrow keys -- up and down.
2. Enter DDP1011. I used the right arrow key but maybe the "enter" key will work too.
3. Select GAMMA using the up or down arrow key.
4. I entered GAMMA using the right arrow key, but the "enter" key may also work.
5. I used the right and left arrow keys to change the value of GAMMA.
6. I used the up arrow key to return to the DDP1011 menu. Again, the "enter" key or "menu" key might do the same thing.
7. I returned to the main SM with the "menu" key.
8. Power off and wait for a full shut down to save entries that you have changed in the SM.
9. Power on after about 30 seconds and enter your user menu picture settings.
This change to GAMMA makes "some" owners happy. I feel that after setting GAMMA to zero and setting brightness with the DVE DVD that the details in dark scenes were improved. To really get the most out of our set I am getting an ISF calibration done by SethS.
As of 12/14/2004:
Mode = Cinema
contrast = 90
brightness = 45
sharpness = 0
color = 48
Digital NR = OFFDNIe = OFF
Enjoy.
