Hi guys need some help.
I been using this monitor for few years now. And yesterday it is suddenly power off itself. I try to replug the power cord, use different power source and different cable.. It will power up back for few second and gone off again.

And today i try another new power cord just power it up without turning on my pc. My monitor stay in power saving mode for hours no issue, but once i power up my pc the same issue happen again.

Does it mean my monitor already “kong” or somethibg to do with my pc.

the power supply unit prolly dead. fixable, but idk whether it is economical

not totally kong...
change the psu at the back of your monitor...
get seller sell this thing, other wise get change at your monitor service centre....
and some times, other brand service centre can also change it,
not sure the price...

i change last 7~8 years, monitor AOC at Viewsonic service centre

Noted thanks guys. Will check how much this monitor psu will cost me.. 👍
