Thanks that worked can I ask what it does ? I've only had the TV 6 weeks
It's hard to explain but It depletes any residual charge in capacitors and unlatches semiconductor switches etc.
It's the first thing to try with any electronic equipment with weird symptoms.
Anyway, glad to hear it cured it.

I’ve had to power cycle my LG C1 twice in the 12 weeks I’ve had it. Once because the HDMI ports stopped working and tonight when we suddenly got a black screen, no video or sound and no response from the remote.
I’ve never had to do this with any other tv I’ve owned, is this a common trait with OLEDs or just a poor build from LG?

I have had my LG OLED since 2014, and have never had to power cycle it.
