One of your close-up photographs shows that your machine has some leakage of a large electrolytic capacitor in your power supply.
Six of my eight functional Panasonic 2006 models developed varying degrees of leakage with the largest power supply electrolytic capacitor.
My first DMR-ES15 now has around 2,900 recording hours. This machine is still functional but exhibited leakage from this electrolytic capacitor. I also have three other functional DMR-ES15 models, two of which evidenced this capacitor leakage.
Three of my four functional DMR-ES35V models also exhibit this capacitor leakage. These three average over 3,000 recording hours per machine.
In the last week I replaced the leaking capacitors in three of my DMR-ES15 models. Next I shall turn my attention to the leaking capacitors in three of my DMR-ES35V models. Different models use different specification capacitors in the power supply. (C1143 in a DMR-ES15 is 100uF 350V 105 degrees; and C11108 in a DMR-ES35V is 220uF 250V 105 degrees.) At my local electronic parts supply store I special-ordered these electrolytic capacitors. These were priced less than $4.00 each.
Replacement of electrolytic capacitors in my models requires dissassembly of the machine to the extent of removal of the chassis motherboard from the case.
Be sure to leave the machine's power disconnected overnight before the procedure. Observe capacitor polarity when removing the old capacitor and soldering in the new capacitor.
In my DMR-ES30V models the power supply is located on a platform at the rear center. That power supply uses two large electrolytic capacitors instead of one. These models do not exhibit capacitor leakage. (One of my DMR-ES30V models has over 4,200 recording hours and the other one has around 2,300 recording hours.)
