There’s nothing more frustrating than sitting down to watch your favorite show… and seeing a “No Signal” message or a blank screen. If your TV cable isn’t working, don’t panic — it could be a simple fix, and we’re here to help.
At Gary’s Computer Repair Service, we fix all kinds of TV signal and cable issues for homes and businesses across Dublin, whether you’re using satellite, cable boxes, HDMI, or antenna connections.
🔍 Common TV Cable Problems
1️⃣ No Signal or Black Screen
Often caused by a loose cable, wrong input source, or signal dropout from your provider.
2️⃣ Flickering Picture or Static
This may be due to a damaged coaxial cable, weak signal, or a loose wall connection.
3️⃣ HDMI Port Not Working
If you’re using HDMI and nothing shows up, it could be a bad cable or faulty HDMI port on the TV.
4️⃣ Audio But No Picture (or Vice Versa)
Sometimes, a worn-out or cheap cable can send partial signals — leading to sound without video or the reverse.
5️⃣ Cable Box Not Connecting to TV
Outdated software, input confusion, or a failing box can stop your connection completely.
