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.
Be sure to check for
latest parts updates.

TROUBLESHOOTING VIDEO PROBLEMS
1.
Verify Video Operation
a)
b)
c)
Customer Picture Test (models available)
“On Screen Display” (If OSD ok, source is
suspected)
Substitute with known good Source (external DVD
or Signal Generator)
2. Use Test Patterns in Service Mode
a)
b)
c)
Select an active source signal (HDMI preferred).
Test Pattern may rely on signal source to appear.
Using customer remote: Mute+1+8+2+Power
Using factory remote: Info+ Factory
ON SCREEN FAILURE EXAMPLES:
2011 LED TV Test Patterns
If Picture & Display errors, its likely a defective
Main Board, LVDS, or T-CON
1.
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
Select an active source signal (HDMI preferred).
Test Pattern may rely on signal source to appear.

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

Check/Set Option Bytes
Check/Perform Firmware upgrade for all
repairs
Perform reset in Service Mode and Plug &
Play if Main is replaced
Inform customer all settings will reset if
Main PCB is replaced
To enter Factory Mode:
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.
