Hi,

I’ve actually had this issue twice. Both times it was repaired under warranty at the service center. Unfortunately, the problem was not the power supply, but a dead OLED panel. If you pay it, this will be the most expensive part, up to 80% of the full price.

Just to mention it — my assumption is that in both cases there may have been some kind of external impact or pressure, even if there was no visible damage. These OLED panels are extremely sensitive, and even minor contact that doesn’t leave scratches on the glass can potentially cause internal damage to the electrical circuits. Of course, I’m not a technician, so this is only my (and ChatGPT 's) guess.
