How To Fix A TV’s HDMI Ports That Is Not Working
Repairing a damaged HDMI port on television is doable. However, it isn’t easy. Therefore it should only get done by someone comfortable with soldering tiny connections.
It is best to avoid repairing your TV if it is under warranty. Therefore, you should take it to the manufacturer if you want to make any repairs. Here is how you can fix a TV’s HDMI port that is not working.
Steps Of Fixing A TV’s HDMI port

The next step is taking off the TV’s exterior casing. You should ensure you are patient and gentle when operating on each different set. Look for screws keeping the housing in place if it won’t come off on its own and remove them.
You will then examine the HDMI port that has been damaged. You will ensure you look for broken connections between the port and the circuit board to which it is attached. Moreover, check the circuits with the continuity tester if you don’t see any breaks.
Using two probes, connect one to the port’s pin location. Connect the other probe to a solder point on the circuit board corresponding to that pin’s location. The HDMI port has 19 pins. However, not all of them will get connected to the TV’s circuits.
If you locate a broken connection, re-solder it. Moreover, re-solder the original plug if the damage to the port is limited to a few broken solder points. To ensure that everything is working as it should, conduct a second continuity test after you’ve finished.
In some instances, the HDMI port might get physically damaged and hence cannot be repaired. If this happens, remove the solder from the port. However, you should ensure that you first observe the circuit board’s connection before you start.
Afterward, remove the molten solder with the de-soldering pump after heating the solder connections. Once you finish doing that, remove the HDMI port that is faulty. You will then connect the new HDMI port to your circuit board by soldering it in place. In addition, make sure that you match the pin connections on your notes.
