Sony TV Has No Sound: Complete Audio Repair on Luthuli Avenue

Sony TV Has No Sound: Complete Audio Repair on Luthuli Avenue

A Sony television with a perfect picture and no sound frustrates every viewer in the room, yet audio faults are among the most repairable in television service. For Nairobi residents searching for Sony TV no sound repair, Pro-Logic Technologies on Luthuli Avenue restores voice and volume quickly and honestly.

Understanding This Fault

Television audio follows a defined path: sources deliver audio streams, the main board decodes them, the audio processing stage applies volume and effects, and the amplifier drives the speakers. Silence can originate at any link, which is why our diagnosis proceeds stage by stage with reference signals. We first confirm which sources are silent, then trace the path through processing to amplification to the speakers themselves. A headphone-detection circuit stuck in the engaged position is a classic silent killer that closes the amplifier output while every other stage remains healthy, and it costs little to repair.

Common Causes and How We Diagnose Them

1. A stuck headphone-detection circuit that mutes the amplifier while the owner has nothing connected.
2. Failed audio processing stages on the main board or audio board, which stop decoding while video continues.
3. A failed audio amplifier stage, which receives signal but drives no power to the speakers.
4. Speaker faults, including open voice coils and broken internal wiring, verified by direct measurement.
5. Audio settings and output configuration faults, including outputs directed to devices that are not present.
6. Firmware faults following updates that corrupt the audio services until professionally restored.

Our Repair Process at Pro-Logic Technologies

At our Kangari Building workshop on Luthuli Avenue, every repair follows a disciplined, transparent sequence. The television first undergoes a structured diagnostic examination, in which our technicians test each board and stage against factory specification to isolate the true cause of the fault, because television symptoms overlap heavily and guesswork is expensive for the customer. You then receive a written quotation with a plain-language explanation before any work is authorized, and there are no hidden charges. Repairs are performed at component level wherever possible, replacing only the failed parts with genuine and compatible Sony components, which keeps costs low and preserves your television's original configuration. Every completed repair is soak-tested under sustained operation, because faults that appear intermittently reveal themselves under load, and only a television that has passed hours of stable testing leaves our workshop. All work is covered by our service warranty.

Why Nairobi Chooses Pro-Logic Technologies on Luthuli Avenue

Luthuli Avenue has anchored Nairobi's electronics trade for decades, and our workshop carries that heritage forward with modern diagnostic equipment, a deep Sony spare parts inventory, and technicians who repair Samsung, LG, TCL, Hisense, Philips, and every major brand daily. That daily breadth across brands sharpens the expertise we apply to every Sony set. Our pricing is written and transparent, our turnaround times are among the fastest in the city, and our advice is always honest: if a repair costs more than your television is worth, we will tell you so plainly, and if the fault lies outside the set, we will say that too and save you the money. Please do not attempt internal repairs yourself; television chassis carry residual voltages, and untrained handling frequently turns a modest board repair into a total loss.

What to Expect at Our Workshop

When you bring your Sony television to our Luthuli Avenue workshop, you can expect a professional experience from the moment you walk through the door. Our reception staff will register your set, note the model number and the symptoms you have observed, and issue a tracking reference so that you can follow the progress of your repair. Diagnosis is conducted on a dedicated bench under the supervision of a senior technician, and we encourage you to describe the circumstances of the fault in your own words, because details such as a recent power cut, a software update, or a house move frequently hold the decisive clue. Once the fault is isolated, we telephone you with the findings and the written quotation, and no work proceeds until you have approved it. If you cannot visit in person, we also accept televisions delivered to Kangari Building, and we can arrange pickup of large screen sizes anywhere within Nairobi for a modest transport fee.

FAQs

My TV has picture but no sound at all. What is the most common cause?
In our workshop it is the audio processing or amplifier stage, both of which are repaired at component level economically. We trace the path stage by stage so you pay only for the link that has actually failed. Call 0723 763 173 or 0101 763 173, or email info@televisionrepair.co.ke, and let Pro-Logic Technologies restore your Sony television promptly and professionally.

How much does this Sony TV repair cost in Nairobi?
The cost depends on your television model and the exact component that has failed, which is why we never quote over the phone without diagnosis. Component-level repairs are generally the most affordable route, and full board replacements are quoted by model. We provide a written quotation after diagnosis, and the diagnostic fee is waived when you proceed with the repair.

How long does the repair take?
Most repairs are completed within one working day, and many walk-in customers from the CBD collect their television the same afternoon. Repairs that require special-order parts for less common models may take two to three days, and we always communicate the realistic timeline before work begins.

Do you repair all Sony TV models?
Yes. We service every Sony BRAVIA generation, from the latest OLED, QD-OLED, and Mini LED models through LED LCD, CCFL-era LCD, and legacy plasma sets, using model-specific service documentation and matched genuine and compatible parts.

Do you offer a warranty on this repair?
Yes. Pro-Logic Technologies provides a service warranty covering both workmanship and the parts we install, giving you confidence that the fault has been properly resolved rather than merely masked. For details about your specific fault, call 0723 763 173 or 0101 763 173, or visit us at Kangari Building, Luthuli Avenue, Nairobi.
