Sony BRAVIA restarts while watching TV

A brief black screen followed by the same program may be a signal interruption; a logo and full startup indicate a restart; a TV in standby may have been turned off. Record the status light, whether sound continues, elapsed time, current input, and whether the remote or a connected device was used. Sony’s support guidance specifically separates regularly timed power events from HDMI-linked power behavior. Do not label every black screen as a reboot before watching what the TV does next.

1. Watch the next event and note whether a Sony logo/startup sequence appears.

   A logo confirms a restart path; standby without a boot sequence suggests power-off behavior.

   If that does not help: If there is smoke, burning smell, liquid, or unusual heat, unplug if safe and contact service.

2. Note the time interval and whether the event happens on a built-in app, broadcast, and HDMI source.

   A repeatable schedule or one-source pattern narrows the likely branch.

   If that does not help: If it happens unpredictably on every source, preserve the frequency and status-light details for Sony.

If shutdown happens at regular intervals or after inactivity, inspect Sleep Timer, Scheduled Power Off, Idle TV Standby, Auto Shut-Off, and energy-saving controls using the exact model menu. Sony documents these as separate features: some react to inactivity, some to a preset time, and some to no input signal. Disable only the matching setting if it is unintended. See the sleep-timer guide for that distinction; do not turn off all energy options without understanding their effect.

1. Check Sleep Timer and scheduled Power Off for a matching countdown or clock time.

   A matching timer can explain a repeatable shutdown without an internal restart fault.

   If that does not help: If no timer is active or the TV reboots to a logo, continue to source and software checks.

2. Check Idle TV Standby/Auto Shut-Off only if the event follows inactivity or no signal.

   These controls should match the observed pattern if they are responsible.

   If that does not help: Restore unrelated energy settings after the test.

Sony notes power events can coincide with an HDMI-connected device being turned on or off. If the restart occurs only when a console, receiver, or set-top box changes state, check HDMI control/BRAVIA Sync and the connected device’s power behavior. Do not disable every CEC setting at once; record the current configuration and test one device at a time. If the TV also restarts while using a built-in app, HDMI control is less likely to explain the entire problem.

1. Compare a built-in TV app with the HDMI source during ordinary use.

   A symptom limited to one external device points toward its control or signal path.

   If that does not help: If it recurs on built-in apps too, report that broader pattern to Sony.

2. If a device event lines up with the restart, consult both manuals for HDMI control and test one documented setting.

   A controlled change can reveal whether automatic device control is involved.

   If that does not help: Restore the setting if it does not change the behavior; avoid service-menu adjustments.

Sony recommends a normal soft reset as an early troubleshooting step and keeping the TV software current. Use the restart procedure for the BRAVIA model; do not disconnect power during an active software update. Confirm the power cord is firmly seated and, if the manufacturer permits, compare a direct wall outlet against a suspect power strip. A power strip test is a comparison, not proof of an internal fault. Never open the TV chassis or handle damaged mains wiring.

1. Perform a normal remote soft reset using Sony’s model guidance.

   If the problem stops, temporary software state may have contributed.

   If that does not help: If restarting does not help, record the result rather than repeating it continuously.

2. Check for an official software update for the exact model and let an active update finish without interruption.

   A supported update can address software issues.

   If that does not help: If the update itself fails or the TV loops after it, contact Sony before attempting recovery.

If BRAVIA continues rebooting across built-in and external sources after timer checks and a documented restart, record the model, software version, event interval, status-light pattern, and whether another outlet changed the symptom. Contact Sony support, especially if an LED flashes or the TV cannot remain on long enough to use menus. A factory reset erases setup and should follow Sony’s model-specific guidance; it is not a substitute for power or hardware diagnosis.

Why does my Sony TV restart every 30 minutes?

Sony documents timers and idle/power settings that can act on a schedule or inactivity. Compare the interval with those settings and confirm whether a full startup logo appears.

Could an HDMI device make my BRAVIA turn off?

Sony notes that power behavior can relate to an HDMI-connected device. Compare built-in apps and the external device, then test the documented control setting.

Should I unplug a Sony TV that is updating?

No. Let an active software installation finish according to the model’s instructions; interrupting firmware can create a separate problem.
