Service Menu
From Samsung Plasma TV FAQ
Contents |
A lot of this information comes from the Service Manual.
[edit] What is the service menu?
The service menu is an easter egg intended for Samsung service technicians. It permits access to hidden factory settings for use by trained field technicians.
[edit] How can I access the service menu?
To Access the Service Menu: Turn the power off. On the remote, press Mute followed by 1, 8, 2, Power in sequence. You should now see the service menu. To exit the Service Menu always select RESET.
WARNING:
Upon entering the Service Menu, all User Menu settings will revert to factory defaults. This includes all display settings, input assignments, channel programming, etc., and applies even if no changes are made while in the Service Menu (viewing the number of panel hours, for example). Document your existing settings beforehand.
- Record any changes made while in the service menu. Use the tables in chapter 4.2 of the Service Manual as a reference.
- There is no known means of restoring the entire service menu to its original factory settings. Although chapter 4.2 of the Service Manual does appear to document those settings, they have not been confirmed to be the factory defaults. You can at least restore any HDMI input settings using this method.
- Samsung reserves the right to void any warranty claims if you or any unauthorized person modifies settings within the service menu.
- Proceed at your own risk.
- Some users have reported that if you do not select RESET when leaving the service Menu some settings especially brightness will be off.
- Some users have reported that when selecting RESET in the service menu your TV Hours On will be reset to 0.
[edit] Alternative method
http://www.fixandsave.co.uk/index.php?view=article&id=115 correctly led me to this method on my UE40C5100QWXXU:
- Put the TV into standby
- Press the {INFO} {MENU} {MUTE} {POWER} buttons on the remote within 3 seconds (in that order; one-by-one)
- Use the {POWER} button to exit the Service Menu.
[edit] I own a HPT-4254 or HPT-5054. Can I enable the USB port to view JPGs and play MP3s?
The ability to view JPGs and play MP3s via the side panel USB port is a feature on the xx64 model line only! However, if you own a xx54, you "may" be able to enable the WISELINK feature.
NOTE: The success of this following WISELINK activation process has only been confirmed by a single 5054 owner. Numerous 5054 owners have reported they followed these steps and it did not enable WISELINK. There have been no reports of success among any 4254 owners using this process.
- Upgrade to firmware version 1039 if you haven't already done so.
- Access the service menu.
- Press the reset option. The television will turn off.
- Turn the television on.
If successful WISELINK should now be listed in the input menu. If it is, load some JPGs or MP3s on a thumb drive, place the thumb drive in the side-panel USB port, and you should be able to display the images or play MP3 audio files.
WARNING: Be sure you read and understand all the warnings associated with updating firmware before attempting this patch.
[edit] Hotel Mode
Hotel mode is a mode for locking down menu access and input selection on the display. It is intended for use in hotels, health clubs, and other environments to restrict guests from changing the display's settings.
My TV Is Displaying The Words Hotel Mode.
If your TV is displaying the words Hotel Mode, you need to get your TV serviced. To set up a service appointment, call Samsung Customer Care
It probably can be turned off in the Service menu. See Hotel Mode in the Service Menu Options section. To our knowledge, no one has tried selecting this service menu option.
[edit] Service Menu Options
Ok, I am *NOT* an expert here, but going to try to list most of the options available in the service menu and describe what I know. Someone else needs to fill in the blanks. One thing to know is that most of these options are exactly the same ones that are found in the regular menu, just with more options.
1.
- Calibration: STAY OUT. DO NOT TOUCH. You have been warned, this is designed to be run in the factory or onsite with specialized hardware outputting specific images. You can ruin your set if you use this.
