To fix unresponsive buttons on the Sony HCD-GTR333, try the following steps:
1. Perform a Power Reset
- Turn off the system and unplug it from the power outlet.
- Wait for a few minutes, then plug it back in and turn it on.
2. Enter Common Test Mode
- Press and hold the [USB/USB SELECT] button and [GROOVE] button simultaneously for 3 seconds.
- Observe if the fluorescent indicator tube responds.
3. Check for Mechanical Lock (MECHA LOCK)
- Press and hold the [GROOVE] button and [POWER] button for 3 seconds.
- If "MECHA LOCK" is displayed, it may indicate a system lock that needs to be reset.
4. Check Amplifier and Button Response
- Press the [PRESET EQ] button repeatedly to see if “GEQ MAX” appears on the display.
- If this works, other buttons may be operational.
5. Inspect for Physical Damage or Dirt
- Ensure the buttons are not stuck due to dirt or debris. Clean them gently with a soft cloth.
6. Service or Repair
- If the issue persists, a hardware issue may exist. Refer to the service manual for further troubleshooting or seek professional repair.
These steps should help determine if the buttons can be restored to working condition.
