What to do

- Try a different HDMI cable that you know works with another device.
- Test the console on a different HDMI port on the TV, or a different TV entirely if possible.
- Check the console's power light and sounds to confirm it's actually turning on and booting.
- If the console has a safe mode, boot into it, which often forces a lower default resolution.
- Inspect both HDMI ports for bent pins, dust, or debris and clean gently if needed.
- If no combination of cable, port, or TV produces a picture, the console's HDMI output may be damaged.
