In this video we will show how to replace the repair kit for the following Emerson TV
model numbers.
LF501EM5F and LF501EM4A.
This kit includes the following boards.
A power supply, a main board, a key board, and the IR sensor.
We have the images and part numbers on the screen.
Before starting the replacement process, it is recommended to take photos along the way,
so that you have something to reference for seeing what the parts look like originally
in the TV, along with all of the connections.
Be sure your TV is unplugged.
I will start by removing the back cover of the TV, so that I can access the boards.
I will start by replacing the power supply board.
The first thing I will do is disconnect all of the cables from the board.
Next, I will remove the screws that hold the board to the TV panel.
After I have removed the screws, I can lift the board from the panel.
Then I will take my replacement board, line it up correctly and then screw it to the panel
to secure it tightly.
Then I can reconnect all of the cables.
The next board I am going to replace is the main
board.
Once again, I will disconnect all of the cables and then remove the board from the panel,
by unscrewing it.
When removing this ribbon cable, you will want to use your finger to flip up the tab
and then lift out the cable.
Then
attach your replacement board to the panel with the screws and reconnect all of
the cables.
Once again with this ribbon cable, make sure the tab is flipped up, then slide this cable
into place and then lock it by pushing down on the tab.
The next board I will be replacing is the key board.
The key board is located on the left hand side of the TV.
I will start by removing the screws that hold the cover to the key board onto the TV panel.
After I have removed the screws, I will lift up the cover and pull the speaker loose.
Then flip the cover over and lay it down.
Then lay the cover down in place being sure not to pull to hard on that wire.
Here we have the board with one wire connected to it.
I will start by disconnecting this cable from the board.
I will slip my finger under the board and firmly push up to remove the board from the
plastic cover.
Then I will take the replacement board and push it into place and reconnect
the cable.
Then I can put the speaker back in place and reconnect the cover back to the TV panel.
Next, I will replace the IR sensor located in the center of the TV here.
I will start by disconnecting the cables.
The cable on the right just pulls straight out.
After removing the cables, I can then pull the board gently straight out of
the TV.
Then I will need to remove the board from the metal case it is in.
Next, I will put my replacement board into that metal case and then slide the metal case
back into place in the TV.
Then, you can reconnect the two cables that are connected.
You have now replaced all of the boards in this Kit and you can put the back cover back
on the TV.
