ac200max led display not working

Hello there, my Ac200max bought in 2003. The led display is no longer lighting up when switched on.
Can you please help, I would like a repair or a replacement, many thanks.

Hi @Solarsam49 if you screen isn’t functioning send @BLUETTI_CARE a post with as much information as possible and most important your s/n and date of purchase and all firmware versions. You never know there may be a firmware fix for your problem it’s worth a try first. After that it will probably need a repair.

I have tagged @BLUETTI_CARE in this post so they may pick it up sooner.
