In Samsung LED TVs, you'll have differences within the number of boards. Most will have a main board and an influence supply board, while some may have an LED driver board and t-con board.
This TV just features a main board and an influence supply board. Here is that the main board, and here is that the power supply board.
The LED driver can sometimes be built onto the facility supply board as we will see here on this TV.
The t-con board also can sometimes be built onto the most board or into the TV panel.
This TV has the t-con connection here then it runs into the panel.

If you can't power on your TV, the primary thing you'll want to see is that you simply have the TV plugged into an outlet that's working. After ensuring that the outlet is functioning , you'll want to see and see that your TV features a standby light.
If your TV won't power on, and you are doing have standby, then the matter is presumably with either the facility supply or the most board.
The first thing you'll do is to visually inspect the most board and power supply trying to find damaged components.
Here we've a closeup of the facility supply. you'll look over the board and do a visible inspection, trying to find any raised or puffy capacitors or any burnt or damaged components.
Here are some samples of what a puffy capacitor or burnt or damaged component will appear as if . If you've got any damaged components that look this manner , you ought to replace the board.
If there's not a replacement board available you'll also try replacing the individual components or purchasing a repair kit.

When trying to find damaged components, or burn marks, you'll also check out rock bottom side of the board. you'd simply just got to disconnect all of the cables then remove the screws that hold the board to the panel.
Be sure when disconnecting cables and removing screws, that you simply you're taking an image of what the board seems like within the original state with all of the cables connected, then you'll have a reference for once you reconnect all of the cables.
Here may be a closeup of the most board, you'll look over the board and do a visible inspection, again trying to find any damaged components. If you've got any damaged components, then you ought to replace that board.
If you are doing not see any damaged components, then that next step would be to see voltages on the facility supply an the most board.
If you are doing not have the talents or tools to see voltages, but still want to undertake and fix your TV, you'll also replace the facility supply and main board, one at a time, and see if one among those two boards, fixes the matter .
If you're getting to purchase multiple boards and replace them individually, to ascertain if one among the boards fixes the matter , before purchasing, make certain to know the return policy of the corporate you're purchasing from as there could also be re-stocking fees for any returned parts, or parts that aren't returnable in the least .
