Hi and welcome to the site, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.
Initially, are you then considering a DIY (do-it-yourself) repair approach? If yes, do you have access to and familiar with a multi-meter and even a soldering iron?
If yes, can you please post back with clear pictures of the power supply board; top for visual check of capacitors / parts and bottom/trace side for the solder conditions.
The only easy user doable tries would be:
Any and all others would be internal and of course would require repairs.
At some point, it may be more to your advantage to simply replace rather than repairs.
I realize that the above information may perhaps be not what was expected. Unfortunately, there is no quick-n-easy fix and neither is there a workaround; sorry for having to be the bearer of bad news.
