Question 1

the audio keeps cutting out for a second every few minutes when using the built-in speakers. happens on all inputs and apps.

Accepted Answer

DIAGNOSIS This is usually caused by the TV's Audio Dolby Digital Plus output setting conflicting with internal processing, or an issue with the eARC/ARC function even when not using a soundbar. FIX Change the digital audio output format. Go to Settings > Display & Sound > Audio output. Set Digital audio out to PCM. Set eARC mode to Off. Set Pass through mode to Off. Next, disable sound-enhancing features. Go to Settings > Display & Sound > Audio output > Advanced settings. Set Sound mode Sync to Off. Set A/V sync to Off. Restart the TV. IF THAT DIDN'T WORK A system software bug can cause this. Boot the TV into Safe Mode to test. Turn the TV off. Unplug it. Press and hold the physical Power and Volume Down buttons on the TV simultaneously. Plug the power cord back in while holding the buttons. Release when you see the Safe Mode logo. If the audio is stable in Safe Mode, a third-party app is likely causing interference. Uninstall recently added apps. HEADS UP If you later connect a soundbar via the eARC port (HDMI 3), you will need to revisit these settings. Set eARC mode to Auto and Digital audio out to Auto 1 for proper surround sound pass-through.

Question 2

i get this weird flashing or stutter in dark scenes when watching dolby vision content on disney+. doesn't happen with other apps.

Accepted Answer

DIAGNOSIS This is likely the Dolby Vision precision detail processing interacting with the app's streaming profile. The mismatch causes momentary brightness fluctuations, often called "near-black flashing" or "Dolby Vision flicker." FIX First, change the Dolby Vision picture mode. While playing the Dolby Vision content, press the Picture button on the remote. Change the mode from Dolby Vision Bright or Dolby Vision Dark to Dolby Vision Vivid. This uses a different tone-mapping curve. If that helps, go to Settings > Display & Sound > Picture > Adjustments. In the Dolby Vision mode, set Reality Creation to Off and set Random Noise Reduction to Off. IF THAT DIDN'T WORK The issue may be specific to the Disney+ app's implementation. Force stop and update the app. Go to Settings > Apps > See all apps > Disney+. Select Force stop, then Update. If no update is available, select Clear cache. Unplug the TV from power for 60 seconds to reset the video processor. HEADS UP This is a known software-level issue with some Dolby Vision content streams, not a hardware fault. It may be improved or resolved in a future firmware update from Sony. Check for updates periodically.

Question 3

the tv randomly turns itself on in the middle of the night. i have all the bravia sync and wifi power settings off.

Accepted Answer

DIAGNOSIS This is typically caused by an automatic software update check or a malfunction in the Android TV's Quick Start feature. The TV wakes from standby to check for updates or refresh app data. FIX Disable automatic updates. Go to Settings > System > About > Software update. Set Automatically check for update to Off. Next, disable Quick Start. Go to Settings > System > Power & Energy > Quick Start. Set it to Off. The TV will take longer to boot from a cold state but will not wake autonomously. IF THAT DIDN'T WORK An external device connected via HDMI-CEC (Bravia Sync) may be sending a wake-up signal. Turn off CEC on all connected devices individually (e.g., cable box, game console). On the TV, go to Settings > Channels & Inputs > External Inputs > Bravia Sync settings. Set Device auto power off to Off. Set TV auto power on to Off. HEADS UP If the TV is connected to a smart home system like Google Home, check for routines or commands that might be turning it on. Disable the link in the Google Home app as a test.

Question 4

the google tv home screen is so slow and laggy on my a80l, apps take forever to open. it wasn't like this when i bought it.

Accepted Answer

DIAGNOSIS The internal storage is likely near capacity from cached app data, causing system slowdown. The Google TV interface requires free space to operate smoothly. FIX First, clear the cache. Go to Settings > Apps > See all apps. Scroll to and select Google TV. Select Clear cache. Do the same for the Google Play Store app. Next, manage storage. Go to Settings > Device Preferences > Storage. Select Internal shared storage. Review and delete any unnecessary app data or cached files. Ensure at least 1GB of space is free. IF THAT DIDN'T WORK A background process or automatic app update may be causing the lag. Perform a soft reset. Hold the physical power button on the side or back of the TV for about 10 seconds until the unit powers off and restarts itself. This clears active memory without affecting settings. HEADS UP Do not perform a factory reset as a first step. If you must, know that it will log you out of all apps and erase all picture calibration settings. You will need to re-enter all login credentials and re-run the Acoustic Auto Calibration if you used it.

Question 5

how do i clean the screen on this oled? the manual says not to use any liquids but it's got fingerprints and dust.

Accepted Answer

DIAGNOSIS The anti-reflective coating on the OLED panel is delicate and can be damaged by standard glass cleaners, alcohol, or ammonia. Using them will create permanent streaks or matte spots. FIX Power off the TV and let the screen cool. Use a dry, soft microfiber cloth designed for lenses or screens. Gently wipe the screen in a single direction using light pressure. For stubborn smudges, slightly dampen a second microfiber cloth with distilled water only. Wring it out completely so it is barely damp. Wipe the area, then immediately dry it with the first dry microfiber cloth. IF THAT DIDN'T WORK For adhesive residue or oily fingerprints that water won't remove, use a specialized screen cleaning solution that is explicitly labeled safe for OLED/anti-glare coatings. Spray a tiny amount directly onto the dry microfiber cloth, never onto the screen. Test on a small corner first. HEADS UP Never apply pressure to the center of the screen. The panel is thin and flexible. Always support the area you are cleaning with your other hand placed flat against the back of the TV to prevent flexing.

Question 6

the tv keeps saying 'no signal' from my playstation 5 even though it's definitely on and plugged into hdmi 3. have to unplug everything to get it back.

Accepted Answer

DIAGNOSIS This is an HDMI handshake failure, often related to the VRR (Variable Refresh Rate) or 4K/120Hz signal format. The TV's HDMI port is not correctly synchronizing with the console's output signal after sleep or a game change. FIX On the PS5, go to Settings > Screen and Video > Video Output. Set 4K Video Transfer Rate to -1. Disable VRR. On the TV, press the Input button on the remote, highlight the PS5's HDMI port, press the Up arrow, and select Signal Format. Change it from Enhanced Format (VRR) to Enhanced Format (Dolby Vision) or just Enhanced Format. Restart both devices. IF THAT DIDN'T WORK The issue may be with the TV's Bravia Core or Auto Calibration features interfering. Go to Settings > Channels & Inputs > External Inputs > Bravia Sync settings. Set Auto Power Off and Auto TV On to Off. Then go to Settings > Display & Sound > Picture > Adjustments. Set Auto Picture Mode to Off. HEADS UP Always use the included Sony HDMI cable or a certified Ultra High Speed HDMI cable. For this model, HDMI ports 3 and 4 are the full-bandwidth 4K/120Hz ports. If problems persist on one port, try the other.

Question 7

just got this oled and there's a faint high-pitched whine or buzz coming from the back, only when bright white screens are showing.

Accepted Answer

DIAGNOSIS This is coil whine from the power supply circuitry. It is a physical phenomenon, not a defect in the panel. The sound occurs during high brightness, high-contrast scenes because the power regulation components vibrate at an audible frequency. FIX First, disable any automatic brightness features that may be causing rapid power fluctuations. Go to Settings > Display & Sound > Picture > Brightness. Set Light Sensor to Off. Then, go to Picture > Advanced Settings > Brightness. Set Peak Luminance to Medium or Low. This reduces the maximum power draw and often eliminates the whine. IF THAT DIDN'T WORK The whine may be more noticeable in a very quiet room due to specific AC power conditions. Try plugging the TV directly into a wall outlet, not a power strip or surge protector. Ensure the outlet is grounded. Power cycle the TV by unplugging it from the wall for two full minutes. HEADS UP This sound does not indicate impending failure and does not affect picture quality or lifespan. It is a common characteristic of the power design in many OLED TVs, including this model. If the sound becomes a loud buzz or crackle, contact Sony support.

Question 8

my new a80l won't connect to my 5ghz wifi, only sees the 2.4. everything else in the house works fine on the 5.

Accepted Answer

DIAGNOSIS The TV's Wi-Fi module is likely set to a channel width or DFS channel your router uses for 5GHz that the TV does not support. The Bravia's wireless chip has compatibility restrictions. FIX Log into your router's admin panel. Navigate to the 5GHz wireless settings. Change the channel width from 160MHz or 80MHz down to 40MHz. Also, manually set the control channel to a number between 36 and 48. Save settings and restart the router. On the TV, go to Settings > Network & Internet > Set up network connection. Select your 5GHz network and try connecting again. IF THAT DIDN'T WORK A firmware mismatch can cause this. On the TV, go to Settings > System > About > Software update. Select System software update and ensure it's fully updated to the latest version. Retry the connection after the update installs and the TV restarts. HEADS UP The TV's Wi-Fi does not support WPA3-only security. If your router is set to WPA3, you must change it to WPA2/WPA3 mixed mode or WPA2 Personal for the TV to connect.
