Hi and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, is the Panasonic DMR-ES30V completely / electrically dead? ...or does it show some indication of power such as a standby or blinking light(s) ?
...am not sure if this what you meant with "...tried multiple plugs...", but can you please try plugging in the DMR-ES30V to another outlet?
And if this would be an internal hardware issue, 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 perhaps a soldering iron?
Bear with me as I review the repair/Service Manual.
This particular model uses a switch mode power supply and considering its age, the capacitors are highly suspect. These parts tend to leak and can cause power issues including sudden death among others.
All of the above would require that the unit be opened up for visual inspection, voltage/continuity/resistance checks, confirm faults and effect 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.
