Hi all,
I’m seeing some odd artefacts on my Samsung S90F, 65" and can’t figure out what’s causing them. Photo attached. Looks like horizontal gridded lines across the whole screen.
What I’ve noticed so far:
The artifacts stay on screen even after I unplug the HDMI cable, so the source device doesn’t seem to be the cause
They also show up on the TV’s own menus including “No Signal” screen
A hard reset (holding the power button for a few seconds until the TV reboots) makes them disappear completely
After that, they come back after a few days of use including gaming
Setup:
Model: Samsung S90F, 65", latest firmware
Source: PS5 Pro via HDMI [port number]
Picture mode: Game mode / HDR on
TV age: 2 months
My questions:
Is this a known firmware or processing bug, or a sign of a panel / T-con board issue?
Since a hard reset clears it, is it safe to assume it’s not burn-in or permanent damage?
Is this worth a warranty claim, or should I wait for a firmware update?
