Introduction
Now, we know that the fuse is broken. Before proceeding with the guide, note that taking apart almost any TV will void its warranty. However, if you have the same 2011 Dynex 32” model as the guide specifies, this TV is way past its warranty and is also discontinued, so you are more than safe to proceed with the guide.
What you need
Step 1
Fuse
- Unplug the TV and detach all cables.

Step 2
- On a flat surface, carefully lay the TV down with the screen resting on the surface and the stand extending off the edge.
- It is recommended that you place a soft fabric down to ensure the TV is not scratched.

Step 3
- Locate the 4 screws on the underside of the stand.
- Loosen and remove the screws using the attached wings.
- Detach the stand from the stand column.

Step 4
- Locate the 4 screws that attach the stand column to the TV.
- Use the screwdriver to remove the screws.
- Use the tweezers to grab the screws that may be hard to reach.

Step 6
- On the compartments that hold the service port and cable jacks, you will see 5 Input/Output (I/O) screws of a smaller diameter than the others.
- Remove the screws and set them aside.

Step 7
- Unscrew the 10 screws around the perimeter of the TV back cover and use the tweezers to remove them.
- The 2 screws at the top of the TV are a shorter length and should be set apart from the others.

Step 8
- Carefully lift off the back cover. Also, be sure to take care in removing the back from around the port and jack compartments.

Step 9
Locate the Proper Printed Circuit Board (PCB)
- Make sure that the TV is laying with the bottom closest to you.
- The PCB that we are interested in should be the yellow device on the left.
- If you are doing this for a different model, the color may not be the same, and they may be in different locations as well. A good way to determine your PCB of focus is to find the PCB that your power ports are saddled or plugged into, rather than your data-related ports like HDMI, audio, etc.

Step 10
Locate the Fuse
- Looking at the power supply PCB, the fuse should be located down in the bottom left corner next to the power input plug.
- In a different model, the fuse will more than likely be very close to the power input plug.

Step 11
Remove the Fuse
- Use the tweezers to gently lift the fuse out of the snaps that it is saddled in.

Step 12
Verify the Fuse Specifications
- On our model, it will list the required specifications of the fuse on the PCB (for a different model, it may or may not be listed).
- You can check the specs on the old and new fuse by looking on the end of the cap. It should list the voltage followed by the current.
- The fuse that we need for this model should be rated 125V and 5A. You may see the voltage printed as 125V/250V as well; this is equivalent to a 125V rating.
- This is a very crucial step because if the rating is any lower than its intended design, the fuse will likely break again and you will be fixing this again soon. If the rating is any higher, that is putting the circuit at high risk of greater damage.

Step 13
Replace the Fuse
- Gently put the new fuse back into its necessary snaps. The direction does not matter.
- Make sure that it is firmly in place and that the snaps are making good metallic contact with the caps of the fuse.

Step 14
- Carefully replace the plastic cover on the back of the TV, while being certain to maintain proper clearance of the buttons and ports.

Now that the TV is assembled, carefully set the TV in its intended location, plug it in, turn it on, and verify that it is now operational again.
