No input power BR1200G-FR

[Cousinhub68]

Hi,
Trouble with my APC BR1200G-FR
It's now 8 years old, I changed battery pack once or twice but now it seems input module is out.
Incoming voltage is constantly 229-230 volts, no trouble, all ok.
I've got a BR900 which is ok and on the same power net.

Now my when I start my BR1200, pluged or not, it is on battery power, input seems to be dead.

And so, no information on the panel except battery is working and charge.

It's beeping, no test or status available, powerchute says there's 465 volts incoming, which is foolish.

Tried the battery back on the other one, all ok

Does it means I need to buy a new UPS ?
