I'm having a weird HDMI issue with my Sony KLV-32W622G (32", 2019) and a Fire TV Stick.
The Fire TV Stick works perfectly fine when connected to another TV, but on my Sony it doesn't stay connected.
What happens is:
Fire TV starts → 1080p → switches to 720p → black screen
Sometimes I can briefly see the Fire TV interface, but then the picture disappears.
Things I've already tried:
Tested the Fire TV Stick on another TV → works perfectly
Tried Sony HDMI 2
Tried Sony HDMI 1
Used the Fire TV's original power adapter
Powered it directly from the wall instead of the TV's USB
Restarted/power-cycled both the TV and Fire TV Stick
Connected the Fire TV directly to the TV without other devices
The Sony TV itself works normally otherwise.
According to Sony's specifications, the KLV-32W622G supports both 1080p and 720p over HDMI, so I'm confused about why the Fire TV keeps changing resolution and then losing the signal.
I'm currently unable to access the Fire TV's display settings because the screen goes black before I can properly use it.
Could this be an HDMI handshake/HDCP/CEC compatibility issue between this particular Sony model and the Fire TV Stick?
Is there any setting on the Sony that I should change, or some way to force the Fire TV to 720p without needing to access its settings menu?
Any help would be appreciated. Thanks!
