Frequently Asked Questions

Clear information regarding our home theater service process.

Are you an official authorized service center for Sony or F&D?

No. We are an independent multi-brand out-of-warranty repair center. We do not claim to represent any OEM brand.

Can you fix a subwoofer that makes a loud humming noise?

Yes. Loud humming noise is usually caused by open filter capacitors in the power supply or shorted output transistors in the amplifier IC stage.

Do I need to bring all satellite speakers when bringing my home theater?

It is recommended to bring the main subwoofer unit, all satellite speakers, remote control, and connection cables so we can perform a full surround test.

Do I need an appointment before dropping off my system?

Yes. Please call us in advance to schedule a diagnostic appointment before visiting our Virugambakkam center.
