Repair HDMI connector in the TV

HDMI (High Definition Multimedia Interface) is a connector that allows you to transmit high-frequency audio and video signals. This port is present in almost all modern TVs. It is an improved version of the scart connector. HDMI can read higher frequency files.

HDMI Benefits

He has his own merits:

1. You can watch movies in the highest quality.
2. Improved sound quality.
3. The ability to perceive the highest extensions (1440p or Quad HD).
4. Refresh rate above 100 Hz.
5. The device has a modern color palette that accepts several million colors.
6. There is only one digital connection in the interface. This avoids cable clutter.

How to identify the cause of the failure of the HDMI connector in the TV

If during the connection of the device to the HDMI connector of the TV, sound and image do not appear, then something has broken.

First you need to make sure that the connector is broken. You must connect another device to it. If the TV does not work, then the connector needs repair.

Identify the cause of the breakdown by looking at the connector. If mechanical damage is noticed, then the cause is a normal breakdown. Such a problem appears if there was an inaccurate docking with the cable. A complete connector replacement is required.

Attention! If external damage is not noticed, then the breakdown is associated with the burnout of the chip. Usually it burns out due to high voltage. Need to replace the chip.

Why did the connector break?

Connection rules have been violated. In most cases, the HDMI connector breaks after connecting the computer. The power cord for the computer has grounding contacts. They are not used in most homes and apartments. Therefore, during operation, voltage begins to build up inside the system unit. And when you connect the system unit to the TV, it goes to the latter.

Important! The microcircuit has a direct connection with the connector housing, therefore, when exceeding the permissible norms regarding voltage, it burns out.

How to repair your HDMI connector yourself

To repair the connector with your own hands, you need to understand the cause of the breakdown. Most often, everything is connected with the chip. In most cases, it breaks due to improper use of the device. It is necessary to determine what type of chip is installed in our case.

They are of two types:

1. Planar
2. BGA

Reference! Replacing a planar chip is easy. Only basic knowledge in electronics is required. With BGA, things get more complicated. Special equipment is needed here, so an expert is indispensable.

When to contact specialists

You need to contact a specialist in the following cases:

1. If the BGA chip is broken. Repairing this type of device is more expensive than planar. This is due to the fact that only a specialist in this field can carry out repairs. Special equipment will also be required. There are times when replacing the HDMi, you need to make the firmware keys responsible for transmitting video and audio signals.
2. Often when replacing a chip, the image works, but there is no sound. In such cases, the memory chips are checked. They store the parameters of the connector.
3. There are also difficult situations associated with damage. For example, the manufacturer did not make a buffer multiplexer for entry. Instead, he got the input straight into the processor. In this case, there is a risk of damage to the port. But also very often the TV itself breaks. If the processor is knocked out, replacing it does not always help. It may be necessary to completely replace the system board. Such errors can be found in cheap TV models made in haste.
4. There are also microcircuits that can interfere with the operation of the device during combustion. An example is the Philips 32PFL7962D. If the multicompressor is damaged, this TV will completely stop working.
5. It will also be necessary to consult a specialist if a person does not understand the technology at all. He does not know what the TV is made of and what details are inside. An inexperienced user can only make things worse during the repair process.

If the connector breaks down, we first need to inspect it for physical damage. If there are any, we take the TV to the service center. If not, read the instructions to determine the type of chip. You can try to replace it yourself, or take the device for repair.
