Experiencing a sudden loss of picture on your OLED television can be frustrating, especially during your favorite shows or gaming sessions. The Sony A90J screen goes black issue is a common problem that many owners encounter, but the good news is that most causes are easy to diagnose and resolve without professional intervention. Whether the black screen occurs intermittently, happens on specific inputs, or appears completely unresponsive, this guide walks you through proven troubleshooting steps to restore your viewing experience quickly and safely.
Quick Power & Connection Checks
Before diving into advanced settings, start with the fundamentals. Many Sony A90J screen goes black complaints stem from simple power or cable issues that take just minutes to verify.
1
Perform a Hard Power Reset: Unplug the TV's power cord from the wall outlet. Wait a full 60 seconds—this allows the capacitors to fully discharge. Press and hold the physical power button on the TV itself (not the remote) for 15 seconds. Plug the TV back in and power it on. This clears temporary software glitches that commonly cause black screen behavior.
2
Inspect All HDMI Connections: Remove and firmly reseat every HDMI cable on both the TV and source device ends. Look for bent pins, frayed cables, or excessive dust buildup. Try a different HDMI port on the A90J, as individual ports can fail. If possible, test with a certified Ultra High Speed HDMI cable, especially for 4K/120Hz sources like PS5 or Xbox Series X.
3
Test the TV Without External Devices: Disconnect all HDMI cables, USB devices, and streaming sticks. Use the Sony remote to launch built-in apps like YouTube or Netflix. If the internal apps display correctly while external sources show black, the issue lies with your connected device or cable rather than the television itself.
Picture Settings & Software Solutions
If basic hardware checks don't resolve the problem, the Sony A90J screen goes black situation may relate to picture processing settings, firmware bugs, or energy-saving features behaving unexpectedly.

Disable Power Saving & Ambient Light Features: Press the Home button, navigate to Settings → System → Power & Energy → Energy Saving Step, and set it to Off. Then go to Settings → Display & Sound → Picture → Ambient Light Sensor and turn it Off. These automatic brightness adjustments can inadvertently dim the OLED panel to complete blackness in certain room conditions.
5
Update to the Latest Firmware: With the TV connected to Wi-Fi, go to Settings → System → About → System Software Update → Check for Updates. Sony has released multiple firmware revisions specifically addressing black screen and HDMI handshake issues for the A90J. Install any available updates and allow the TV to restart completely before testing.
6
Factory Reset the Television: If problems persist, navigate to Settings → System → Reset → Factory Data Reset. This erases all personal settings, installed apps, and login information, returning the TV to its original software state. Only use this option after exhausting other steps, and note down your current picture settings if you've customized them extensively.
Warning: OLED panels can suffer from permanent burn-in if static images remain displayed for extended periods. However, do not confuse burn-in with the Sony A90J screen goes black issue. If your screen shows no picture whatsoever—even the Sony logo during boot—this indicates a power, signal, or panel driver problem rather than burn-in damage. Avoid repeated hard resets in quick succession, as this can stress the power supply board.
Still Need Help With Your Sony Device?

Why does my Sony A90J screen go black but sound still works?
This typically indicates a picture processing or backlight issue rather than complete power failure. Try the hard reset first, then disable the Energy Saving and Ambient Light Sensor features. If audio persists through internal speakers or soundbar while the panel stays dark, the OLED panel driver or T-Con board may need professional evaluation.
Can a faulty HDMI cable cause the Sony A90J screen to go black intermittently?
Yes, absolutely. Intermittent black screens—especially when switching between SDR and HDR content or changing refresh rates—often trace back to inadequate HDMI cables. The A90J supports 4K at 120Hz and HDMI 2.1 features, which demand certified Ultra High Speed HDMI cables. Standard Premium High Speed cables may cause handshake failures that manifest as brief or sustained black screens.
Is the Sony A90J screen goes black problem covered under warranty?
Sony provides a one-year limited warranty for parts and labor on the A90J, with some retailers offering extended coverage. If your television experiences black screen issues due to manufacturing defects in the panel, power supply, or main board, repairs should be covered during the warranty period. Keep your original purchase receipt and note that physical damage, power surges, or unauthorized modifications typically void coverage.
