Common Causes of Hitachi TV Sound but No Picture Issue – Why does it happen?



There are several common causes for Hitachi TV sound but no picture issues. Understanding these causes can help you diagnose and fix the problem more efficiently. In this section, we will discuss three common culprits:


  1. Faulty HDMI Cables
  2. Damaged Input Ports
  3. Internal Circuit Failure



Faulty HDMI Cables



One possible cause of the Hitachi TV sound but no picture issue is a faulty HDMI cable. HDMI cables are responsible for transmitting both audio and video signals from the source device to the TV. If the cable is damaged or not properly connected, it may result in sound but no picture.

To resolve this issue, try the following steps:

  • Check the HDMI cable for physical damage
  • Ensure that the cable is properly connected to both the source device and the TV
  • Try using an alternate HDMI cable



Damaged Input Ports



Damaged input ports on either the source device or the Hitachi TV can also lead to sound but no picture issues. Input ports can become damaged due to wear and tear, physical impact, or corrosion.

If you suspect damaged input ports, try the following solutions:

  • Inspect the input ports on both the source device and the TV for visible damage or corrosion
  • Try connecting the source device to a different input port on the TV
  • Consider professional repair or replacement of the damaged input ports



Internal Circuit Failure



Internal circuit failure is another common cause of Hitachi TV sound but no picture issues. This can happen due to a variety of reasons, including age, power surges, or manufacturing defects.

Some possible signs of internal circuit failure include:

  • Picture flickering or distortion before disappearing
  • TV shutting off unexpectedly
  • No picture even when using different input sources

If you suspect an Internal circuit failure, it is advised to consult a qualified technician to diagnose and repair the issue, as it may require disassembling and replacing the defective components within the TV.




How to Fix the Hitachi TV Sound but No Picture Issue



Several factors could be responsible for the Hitachi TV sound but no picture issue. This section will provide you with straightforward troubleshooting guidelines to resolve this issue without the need for a technician. Follow these sub-sections to help identify and fix the problem:



Check for Proper Cable Connections

Try Different Input Sources


Switch between different input sources to see if the issue persists. For example, if you were using HDMI, try swapping it with other HDMI inputs or even an alternate cable to rule out a faulty port or cable.

Factory resetting your Hitachi TV can resolve many configuration issues:

  • Locate the TV’s settings menu.
  • Select “Reset” or “Factory Reset.”
  • Confirm the action and wait for the process to complete.



Test Component Cables or Composite Video



When using component cables or composite video connections, double-check that they are firmly connected and inserted into the matching color-coded ports. Try swapping cables to rule out cable damage.




Check Components Are Cleaned (and deep-clean if they’re not!)



Dust and debris can impact the performance of your TV and connected devices. Perform a thorough cleaning by:

  • Unplugging all devices.
  • Using compressed air to blow away dust from ports, jacks, and vents.
  • A gentle wipe-down with a microfiber cloth for surfaces.

  • Intermittent picture loss.
  • Stuttering or freezing images on the screen.
  • Distinctive burning smell from the TV.
