Sony TV Repair in Vizag: 10 Common Problems and Exactly How to Fix Them
If your Sony TV is acting up, you're probably searching for a fast, honest answer — not a sales pitch. Below are the most common Sony TV problems we see in Visakhapatnam, what actually causes them, and whether you need a technician or can fix it yourself in 5 minutes.
We're Sony TV Service Center in Vizag, and we've repaired thousands of Sony LED, LCD, and smart TVs across Visakhapatnam since opening. This guide is based on real repair cases from our service center.
Why is my Sony TV screen black but the sound still works?
This is almost always a backlight failure, not a screen failure. When you can hear the TV but see nothing (or a very dim, barely visible picture if you shine a torch close to the screen), the LED backlight strips behind the panel have failed — the actual display panel and circuitry are usually fine. This is repairable and does not require a full screen replacement in most cases. Cost typically ranges from ₹1,500–₹4,500 depending on the TV size and number of backlight strips needed.
If there's no sound either, the issue is more likely a power supply or main board fault, which is a different repair.
Why won't my Sony TV turn on at all (no red light, nothing)?
A completely dead TV with no standby light is usually a power supply board (SMPS) failure, often caused by voltage fluctuations — common during Vizag's monsoon season and frequent power cuts. Capacitors on the power board swell or burst and need replacement. This is one of the most frequent repairs we handle, especially after storms.
If the red standby light is on but the TV won't switch on with remote or button, the issue is usually the main board or a software/firmware lock, not the power supply.
My Sony Smart TV has no sound but the picture is fine — what's wrong?
Check your audio output settings first (Settings → Sound → Speakers) — many users accidentally switch output to "Audio system" or Bluetooth and assume the TV is broken. If settings are correct and there's still no sound, the issue is typically:
- A blown speaker (rattling or distorted sound before it cut out)
- A faulty audio IC on the main board
- A loose internal speaker connector (common after the TV has been moved or wall-mounted)
Speaker replacement costs around ₹800–₹2,000; main board audio IC repair is higher.
Why does my Sony TV randomly restart or show a blinking red light?
A blinking red light pattern is Sony's built-in error code system. Count the number of blinks before it pauses and repeats — this tells a technician exactly which component failed (panel, backlight, power, or main board) before they even open the TV. Random restarts without blinking are usually overheating from blocked ventilation or a failing power supply.
Don't keep restarting it repeatedly — this can stress the main board further. Unplug it and call for a diagnosis.
Why is my Sony TV Wi-Fi not connecting or apps keep crashing?
This is a software issue, not a hardware fault, in about 90% of cases. Try this order:
- Restart the TV (unplug for 60 seconds, don't just use the remote)
- Forget the Wi-Fi network and reconnect
- Check for a system software update under Settings → System → Software Update
- Clear app cache or reinstall the problem app
If apps still crash after a firmware update, the TV's internal storage may be failing — this needs a technician.
Can a cracked Sony TV screen be repaired, or does it need full replacement?
A cracked panel cannot be "repaired" — it requires full panel replacement, which is the single most expensive Sony TV repair. Depending on screen size (32" to 65"+), genuine panel replacement can range from ₹6,000 to ₹25,000+. For TVs older than 5-6 years, we're usually upfront with customers that replacement cost may not be worth it compared to the TV's current value — we'll tell you this honestly during inspection rather than push the repair.
How much does Sony TV repair cost in Vizag?
Costs depend entirely on the fault, not just the TV size:
| Issue | Typical Cost Range |
|---|---|
| Backlight repair | ₹1,500 – ₹4,500 |
| Power supply (SMPS) board | ₹1,800 – ₹5,000 |
| Speaker/audio repair | ₹800 – ₹2,000 |
| Main board repair | ₹3,000 – ₹8,000 |
| Screen/panel replacement | ₹6,000 – ₹25,000+ |
| Remote/sensor issues | ₹300 – ₹900 |
We provide a free diagnosis before quoting, so you know the exact cost before committing.
Should I repair my Sony TV myself or call a technician?
Safe to try yourself: Wi-Fi/app issues, sound output settings, remote pairing, software updates.
Always call a technician for: anything involving the back panel, power supply, backlight, or main board. Sony TVs use capacitors that can hold dangerous voltage even when unplugged, and opening the unit yourself usually voids any chance of using genuine spare parts later. It also risks turning a ₹2,000 repair into a ₹6,000 one if mishandled.
Is it worth repairing a Sony TV after the warranty expires?
In most cases, yes — if the TV is under 6-7 years old. Sony panels and components are built to last, and a backlight, power board, or speaker repair is almost always cheaper than buying a new TV. We're a post-warranty Sony TV service center in Vizag, so even if your Sony warranty has expired, you don't need to go without support — genuine-quality repairs are still available locally.
