Sony TV 6 Blinking Red Lights – Meaning, Causes & Fixes
Six blinking red lights on a Sony TV is a diagnostic fault code communicated through the LED indicator on the front of the television. Sony Bravia TVs — and many older Sony LCD and LED models — use a blink code system where the standby indicator blinks a specific number of times, pauses, and repeats. Counting the number of blinks identifies the fault. Six blinks specifically indicates a fault in the TV's inverter board or the LCD backlight system. This is a hardware-level error, not a software or network issue. The TV will typically fail to turn on, flash briefly, or go black after a few seconds. While serious, this fault is diagnosable and in many cases repairable without replacing the full television.
What it means
Six red blinks on a Sony TV indicates an inverter board fault or LCD backlight failure — a hardware-level error in the power delivery system for the screen.
Severity
HighCan you fix it yourself?
Partially — a soft reset may temporarily resolve it. Physical repair of the inverter or backlight requires a technician.
Call a technician when
Yes — if the soft reset does not clear the blink code, professional diagnosis is required.
What Does 6 Blinking Red Lights Mean?
Sony Bravia TVs communicate hardware faults through a standby LED blink code system. The LED on the front of the TV (usually red or amber in standby) blinks a set number of times, pauses for 3–4 seconds, and repeats the sequence. The number of blinks maps directly to a specific fault category in Sony's diagnostic system.
Six blinks on most Sony Bravia models (including KDL and XBR series) points to an inverter board fault. The inverter board is responsible for converting the low-voltage DC power from the power supply board into the high-frequency, high-voltage AC power required to drive the CCFL (Cold Cathode Fluorescent Lamp) backlights — used in older LCD models — or to drive the LED backlight driver circuits on newer LED models.
When the inverter detects an abnormal condition — an open circuit from a failed backlight, a short in the backlight driver, or an inverter component failure — it signals the main board, which shuts the TV down and logs the 6-blink code.
In practice, this means the TV may: power on, show the Sony logo or a brief picture, then go completely black while audio continues (backlight failed, panel electronics still running); or fail to power on at all, going directly to the blink code from standby.
On some Sony models, 6 blinks can also relate to the main board or T-Con (timing controller) board depending on the exact model year and series. Always verify your exact model's blink code chart in the service manual, as Sony has used slightly different fault codes across generations.
What Causes This Error?
- Failed CCFL backlight tube (older LCD Sony TVs) — CCFL lamps burn out with age, typically showing as one dark edge on screen before total failure
- Failed LED backlight strip (newer LED Sony TVs) — one or more LED strips in the backlight array have burned out or shorted
- Faulty inverter board — the inverter's output transistors, capacitors, or driver ICs have failed
- Inverter board capacitor failure — bulging or leaking electrolytic capacitors on the inverter are a common failure mode on TVs 5+ years old
- Open or short circuit in the backlight connector cables between the inverter and the backlight assembly
- Power supply board issue feeding incorrect voltage to the inverter board
- Main board or T-Con board fault on certain Sony models where 6 blinks maps to different sub-systems
How to Fix 6 Blinking Red Lights
- 1
Perform a complete power drain reset first. This resolves 6-blink codes caused by temporary firmware faults, not just hardware failures — and it's worth confirming before opening the TV. Unplug the TV from the wall. Press and hold the power button on the TV itself (not the remote) for 30 seconds while it is unplugged. Release, then wait another 30 seconds. Plug back in and power on. Some 6-blink occurrences after a power surge are resolved by this procedure.

Count the blink sequence carefully. Watch the front LED: count each blink, then time the pause before the next sequence begins. Write down the count. On some Sony Bravia models, there is a main blink count and a sub-blink count (e.g., 6 main blinks, then 2 sub-blinks) — the combination is more specific. Look up your exact model number on Sony's support site or the service manual to confirm whether 6 blinks on your specific model means inverter/backlight or a different subsystem.
- 3
Shine a bright flashlight at a close angle onto the TV screen while attempting to power it on. If you can faintly see the Sony logo or a menu behind the dark screen, the panel is producing an image but the backlight is not lighting it. This confirms the fault is in the backlight/inverter system, not the main board or panel itself — a much more repairable scenario.
- 4
Inspect the TV for visible capacitor damage on the power supply and inverter boards if you are comfortable opening the TV cabinet (unplug first, discharge capacitors). Bulging, domed, or leaking capacitors on the board are clearly visible and indicate board-level failure. Capacitor replacement is a viable DIY repair for those with soldering experience and costs $5–$20 in parts.

If the backlight flashlight test confirms a backlight failure and your TV is an LED model (post-2012), the LED backlight strips can often be replaced. LED strips for common Sony Bravia models are available for $15–$50. This repair requires removing the back panel, bezel, and LCD panel to access the strips — it is moderately complex but achievable with the right guides for your specific model.
When to Call a Professional
If a power drain reset does not clear the 6-blink code and you have confirmed the backlight is not illuminating via the flashlight test, the inverter board, power supply board, or LED backlight strips need replacement. Sony-authorized service centers have access to genuine replacement boards and the diagnostic tools to identify which specific component in the chain has failed. Repair costs vary significantly: LED strip replacement $100–$250 including labor; inverter/power supply board replacement $150–$350; T-Con or main board replacement $200–$450. Compare repair cost to the TV's current market value before committing — for TVs over 7 years old, replacement may be more economical.
Can You Still Use the Device?
No. The TV will not display a picture while the 6-blink fault is active. You cannot watch content in any mode while this error persists. The audio system may continue to function (some users report hearing sound with a black screen), but the display is non-functional until the backlight or inverter issue is resolved.
