Is your TV showing “No Signal” on the HDMI port? This is a common issue caused by a handshake error, where the TV and connected device (PC, console, set-top box, or streaming stick) fail to recognize each other.
Riyadh Electronic TV Repair Shop, Uttara Bashundhara provides 24/7 home service across Dhaka for all HDMI port problems. There is no better institution in Dhaka city for professional HDMI troubleshooting and repair.
Common HDMI Port Issues
- TV HDMI port not working
- HDMI port not recognized on PC or laptop
- HDMI 1, 2, or 3 port not working
- LG, Sony Bravia, Walton, Vision HDMI port errors
- HDMI cable plugged but no signal
- Plasma or LED TV HDMI port stopped working
- Type-C to HDMI cable not working
- HDMI splitter issues (4-port, 8-port)
- USB stick or TV card interfering with HDMI
Expert Fixes for “No Signal”
1. The Handshake Reset (Works for 90% of Cases)
Static electricity in ports can cause confusion between devices.
- Turn OFF the TV and the connected device.
- Unplug both from wall power.
- Disconnect the HDMI cable from both ends.
- Wait 2 minutes.
- Reconnect the HDMI cable firmly.
- Plug in the power and turn on the TV first, then the device.
2. Brand-Specific Built-in Diagnostics
- Samsung: Settings → Support → Device Care → Self Diagnosis → HDMI Troubleshooting. Tests the cable and port internally.
- Sony Bravia: Settings → Apps → See all apps → System apps → ExternalInputServices → Clear Data & Cache. Restart the TV.
- LG: Turn OFF HDMI Ultra HD Deep Color for older cables/devices; this often resolves “No Signal.”
- Walton / Vision: Lightning or power surges may burn HDMI IC chip. Test HDMI 2 or 3. If none work, motherboard chip replacement may be required.
