HDMI port not working? We fix it — in your home, across Chicagoland.

What “HDMI not working” usually means

Knowing exactly which HDMI symptom you’re seeing helps us bring the right parts.

• One specific HDMI port is dead, others work fine. The most common case. Usually a board-level repair on that input — the port itself or the input chip serving it. We can often fix just that port.
• All HDMI ports stopped working at once. Less common; usually the input chip or the main board. Repairable but more expensive than a single-port repair.
• HDMI works but HDR / Dolby Vision won’t engage. Often a cable issue (Premium High Speed required for HDR; Ultra High Speed for 4K@120Hz) before it’s the TV. Try a different cable first.
• HDMI 2.1 features (4K@120Hz, VRR, ALLM) fail with PS5 / Xbox Series X. Newer Sony and LG OLEDs are particular about HDMI 2.1 handshakes. Sometimes the input chip needs replacing; sometimes a firmware update fixes it.
• HDMI port has physical damage. Bent pins, loose connector, partial extraction. Often repairable if the damage is to the port mount rather than the board pads.
• HDMI-CEC stopped working. Soundbar volume control or auto-power-on no longer works. Usually a settings issue or eARC chain problem, not a port failure.

Try these before you call

A meaningful share of HDMI “failures” aren’t the TV at all. Try these first.

1. Try a different HDMI cable. Cheap or old cables fail surprisingly often, especially for 4K and HDR. A new $15 cable is the cheapest possible diagnostic.
2. Move the device to a different HDMI port. If your cable box is on HDMI 1 and HDMI 1 is dead, try HDMI 3. If the device works there, the issue is confirmed to be that specific port on the TV.
3. Power-cycle both ends. Unplug the TV and the source device (cable box, PS5, soundbar) from the wall for two minutes. Plug both back in. HDMI handshake issues sometimes resolve.

What we do on the in-home visit

Our tech arrives, opens the back, and tests the affected HDMI port’s voltage, data lines, and continuity to the input chip. Diagnosis takes 15–25 minutes. If it’s a port-level repair we can often do it on-site with replacement port mounts and re-soldering. If the input panel or main board needs replacing and we don’t have the model-specific part, we order it and return to install with no additional service-call fee.

Typical cost ranges

Prices include parts and labor. Final number depends on brand, size, and exact failure. We quote in writing before starting.

When repair doesn’t make sense

If your TV is over seven years old and only one HDMI port has failed, sometimes the simplest fix is just to use a different port and skip the repair. We’ll be honest with you on the phone — if you have a working port, the repair might not be worth the call.
