HOT TIPS
Power On Problems: (see page 2) Video Problems: (see page 3) Other: If the set loses internet connectivity, the remote control no longer operates, and the 3D glasses will not link to the set, verify power supply voltages. If they are normal , replace the main board as that is the only commonality between all of the failures.

TROUBLESHOOTING VIDEO PROBLEMS
1. V erify Video Operation
a) Customer Picture Test (models available) b) “On Screen Display” (If OSD ok, source is
suspected)
c) Substitute with known good Source (external DVD
or Signal Generator)
2. Use Test Patterns in Service Mode
a) Select an active source signal (HDMI preferred).
Test Pattern may rely on signal source to appear. b) Using customer remote: Mute+1+8+2+Power c) Using factory remote: Info+ Factory
ON SCREEN FAILURE EXAMPLES:
If Picture & Display errors, its likely a defective Main Board, LVDS, or T-CON
Green lines or a green screen likely caused by a defective main board, LVDS, or T-CON
Vertical or Horizontal Lines are likely a defective panel, but also T-CON, LVDS, or Main Board. Use Test Patterns in Factory Service Mode to determine error location
Pixelization can be caused by the main board, but is more commonly a source error
2011 LED TV Test Patterns
1. Select an active source signal (HDMI preferred). Test Pattern may rely on signal source to appear.
2. Access Service Mode
3. Access SVC
4. Access Test Patterns
5. Access Genoa-P (located on Main PCB)
6. Check Test Patterns
7. If OK, suspect input Source
8. Access Napoli (located on T-CON Board)
9. Check Test Patterns
10. If OK and Genoa-P was not good, suspect Main Board or LVDS Cable

Software Upgrade:
Software Upgrade can be performed by network connection or downloading the latest firmware from “www.samsung.com” to a USB memory device.
- By USB Insert a USB drive containing the firmware upgrade file. DO NOT disconnect the power or remove the USB drive until upgrades are complete. The TV will be turned off and on automatically after completing the firmware upgrade. When software is upgraded, video and audio settings you have made will return to their default settings.
NOTE: The displayed menu may differ depending on the model.
- By Online
Upgrades the software using the Internet. First, configure your network. If The internet connection doesn’t operate properly, connection can be broken, please retry downloading. If the problem still happens, download by USB and upgrade.
- Standby mode upgrade(Off/On)
A manual upgrade will be automatically performed at selected time. Since the power of the unit is turned on internally, the screen may be turned on slightly for the LED product. This phenomenon may continue for more than 1 hour until the software upgrade is complete.
Testing Bluetooth Operation (3D glasses and QWERTY remote):
Bluetooth communication will automatically activate when the TV is turned on. To test, use a cell phone with Bluetooth capabilities, and “SCAN for devices”. If Bluetooth communication is working properly, “DTVBluetooth” will appear on the phone. If not, suspect Main PCB, or Bluetooth module is defective.
