po-12 screen broken/dimmed/voltage issue


My po’s screen worked for like 10 days, and after it starte to being dimmed.
Firstly, the little man, after the knobs settings and finally the rest.
I got it for Christmas and I’m a little sad about it.
I tried to change the batteries, and I sent a mail to te but they didn’t responded ( it seems to be the holidays for them )

Anyone had this issue by the past ?
The sound works however but I think I’ll just see if I have any guarantee
