Good sound makes a TV feel complete — whether it's a 5.1 home theatre for movies, a soundbar under the TV, or a HiFi amplifier and speakers for music. City Electronics repairs all of them, along with the TV, at one place in Aligarh.
Audio equipment has its own common faults: amplifier sections blow from high volume or shorted speaker wires, power sections fail after surges, and Bluetooth, optical and HDMI ARC connections develop problems. We diagnose the system as a whole, including how it connects to your TV, so the fix actually solves the problem you notice at home.

Frequently asked questions
Should I bring the speakers too?
Please bring the main unit and, if possible, the subwoofer and speakers — it helps us find faults faster.
Do you repair old HiFi amplifiers?
Yes, we repair older amplifiers and music systems as well as modern soundbars.
My soundbar works on Bluetooth but not with the TV. Why?
Usually an HDMI ARC or optical setting, or a faulty port. We check both the TV and the soundbar.
