There have been a number of posts in this and other threads or forums that mention failed or failing power supply capacitors in Panasonic DVD recorders, combo recorders and hard drive recorders. Some of these posts are mine.
With my (2006 model) DMR-ES35V combo recorders and DMR-ES15 DVD recorders I have found that the culprit is the largest electrolytic capacitor in the power supply section.
With DMR-ES35V models the power supply is part of the right chassis motherboard; with a DMR-ES15 the power supply is part of the main chassis motherboard. Replacement requires extensive disassembly. The whole procedure takes one hour + per machine.
The largest electrolytic capacitor in the power supply sections in DMR-ES15 and DMR-ES35V models are not of the same specification. In a DMR-ES15 model C1143 is 100uf 350v. In a DMR-ES35V model C11108 is 220uf 250v. Both have a heat range of 105 C degrees, and are 30mm tall. I ordered replacement capacitors for both models through a local electronic parts store. These capacitors have the same specification as those used by Panasonic but they are from a different manufacturer.
In February 2008 I replaced the leaking power supply capacitors in three of my four DMR-ES15 models. The recording hours for the four DMR-ES15 models is (currently) 2,966, 988, 330 and 845, respectively. My fourth DMR-ES15, the one with 845 recording hours, continues in daily use with its original capacitor that did not evidence leakage at the machine’s most recent DVD drive service.
After capacitor replacement all three of the DMR-ES15 models checked out OK; two were placed into regular daily service (one for a month or so) and the third, the one with but 330 recording hours, was set aside for standby use.
In the last week one of those DMR-ES15 models that had capacitor replacement in February had experienced a recording failure and was removed from service. The second DMR-ES15 that had capacitor replacement in February was swapped in to replace the machine with the recording failure. That machine had no difficulty recording but it is unable to finalize a disc so it was also removed from service. (The disc was finalized on the DMR-ES15 that remains functional.) The third DMR-ES15 that had capacitor replacement in February was then swapped in but it was found to be â€œdeadâ€ (a common indication of capacitor failure). Today my original DMR-ES30V (in semi-retirement with 4,212 recording hours) was put back into daily service.
I also own four DMR-ES35V models. Three of the four evidence leakage from the largest electrolytic capacitor in the power supply. Those models were set aside for capacitor replacement in January/February 2008 but I have not had an opportunity to replace the capacitors in the those three models. The recording hours for the four DMR-ES35V models is (currently) 2,985, 3,140, 3,065 and 480, respectively. My fourth DMR-ES35V, the one with 480 recording hours, continues in daily use with its original capacitor that did not evidence leakage at the machine’s most recent DVD drive service.
I also own two DMR-ES30V models. These 2005 models differ from the 2006 models in that two large (matching) electrolytic capacitors are used in the power supply section that is mounted on a platform at the rear of the case. The recording hours for these two DMR-ES30V models is (currently) 4,212 and 2,680, respectively. (Neither DMR-ES30V evidenced capacitor leakage at its most recent DVD drive service.
Some of my Panasonics were purchased new, some were purchased refurbished (by Panasonic) and some were purchased used. When I mention â€œrecording hoursâ€ these figures are from recording utilization records I maintain for machines while they are in my service.
