In
this video we will show how to replace the main board, the power supply board, the
t-con, and the wifi module.
These are all included in the Samsung UN46EH5300FXZA Complete LED TV Repair Kit.
It is recommended to take pictures during the repair process to use as a reference point.
Be sure your TV is unplugged.
There are two back covers on this TV.
Removing the first one will allow you access to the main board, the power supply board
and the wifi module.
The outer frame on the back cover will need to be removed, before replacing the t-con
board.
The first board we are going to replace is the power supply board.
I will start by disconnecting all of the cables and connections on the board.
I will remove all of the screws that hold the board to
the TV panel.
I will slide my replacement board into position and then tighten it to the panel with
the screws.
I will reconnect all of the cables and connections on the board.
The next board we are going to replace is the t-con board.
The t-con board can be covered with a shield that needs to be removed.
Start by disconnecting the LVDS cable and ribbon cables at the t-con.
These connections are very fragile.
Remove the screws and the board from the chassis.
Align the replacement t-con board and install
the screws.
Reconnect the LVDS and ribbon cables.
If there is a shield, reinstall that.
The next board we are going to replace is the main board.
Start by disconnecting all of the cables and connections.
Remove all of the screws and the board from the chassis.
Align the replacement board and install
the screws.
Reconnect all of the cables and connections On
the board.
The last board I am going to replace is the wifi module.
I will disconnect the module from the cable and then firmly lift it from the chassis.
For this TV, it is held to the chassis with some glue.
Reinstall the replacement wifi module and connect it to the cable.
Adhere the module to the chassis, using the existing glue.
Some TVs may have a clip or screw that holds the wifi module to
the chassis.
