Usually, but not always, capacitors will show visible signs of failure. There are two main types Samsung UN55D6900WF LED TV visible failure. When it fails, the chemical reaction inside the capacitor can produce hydrogen gas, so capacitors have vents cut into the tops of their aluminum cans. These are intended to break and release the gas that has built up inside the capacitor.
So, a capacitor which has failed can show bulging at the top. Below is an example.

Another sign of a failed capacitor is leaking fluid electrolyte. This can be an orange or brownish discharge from either the top or bottom of the capacitor.

Usually, with leaking the capacitor will also be bulging. But a capacitor can bulge but not leak. Again, we want to emphasize that capacitors do not always show visible signs of failure. But, if you see signs of this on your board, you can be confident that you're close to fixing your TV. If you don't see these signs of failure, but your TV had the tell-tail clicking sound, you still can be fairly certain the steps below will fix your TV.
Identifying the Problem Capacitors If you have a Samsung Series LCD and perhaps other modelsand you came to this site because your TV won't start, and it makes Samsung UN55D6900WF LED TV clicking sound, then the picture above shows the Samsung UN55D6900WF LED TV that should be replaced in the red box. If you have a different make or model you will need to visually inspect and replace any damaged capacitors.
Below are actual closeups of my TV's board.
Notice how the blue capacitors in the foreground are bulging. These are the capacitors I will replace. All other capacitors look OK. If you can find replacements for all 4 of these capacitors, and any others that show visual signs of going bad, I recommend replacing them all while your in here.

I couldn't find the specific Samsung UN55D6900WF LED TV for the "black" capacitors uf 25V at my local electronic store, and since they looked OK, I just replaced the the bulging ones. But again, if you can find replacements, and since the capacitors are cheap, replace all 4 of these if possible and any other ones showing signs of damage while your working in here.
Remove Capacitors Capacitors have polarity. Before removing any capacitor, note which side the white stripe of the capacitor is facing.
You will need to put in the new capacitor in the same direction. You probably noted on my pictures that I actually made a note on the aluminum heat sink with a pen.
Now that you've identified the capacitors that look bad, turn the board over and carefully identify exactly which points on the board the wire leads from the these capacitors. Circle them with a "sharpie" type pen to keep track. Grab your friend Samsung UN55D6900WF LED TV have them help you on this next step.

Balancing the circuit board on its side while using a hot soldering iron and pliers can be a bit tricky. Plug in the soldering iron and give it 10 minutes to get hot.
With the circuit board on its edge, have your friend grab one of the capacitors with the pliers and apply a very gentle pulling pressure. Apply the tip of the soldering iron to one lead on the back side of the board and hold it there until you see the solder melt.

Now switch to the other lead until it melts. Keep going back and forth on the leads.
Each time the solder will melt faster. After going back and forth a couple times the capacitor will easily come out. Repeat for each capacitor that you are replacing.
Let the iron do the work. If the capacitor does not easily pull out, do not force it.
