I have an as yet unproven speculation about a possible problem area on the tuner board of the EH60D [ sister of the ES20D ] ... namely capacitor C701...
I'm assuming this board will be the same on the ES20D, and it is a possible candidate for a cause of this problem. For more detail and a picture - see post no 4 in this thread here. |

Are you sure it is not the slipping disc syndrome which overcomes all these machines after a time?
Cleaning the rubber grip ring on the disc platform is the remedy. There are threads about this elsewhere. The ES20D is generally fine apart from the retuning issue, which must surely be software since we're all suffering it... annoying, but livable with on an otherwise reliable machine. |

My contact in Panasonic c/service assures me that they are aware of a problem affecting this model together with another one - possibly the DMR E60DEB, I can't be 100% sure.
Although they have seen the problem they are currently soak testing them but have been unable to replicate the exact fault.....well, at least they appear to be trying. Will update if I hear anything |

I know this is an old thread but did the re-tuning issue (no freeview channels) ever get resolved ?
Thanks |

I've recently done a re-tune ending up with no freeview stations at all but unplugging the recorder for 15 minutes and then re-tuning brought all the freeview stations back.

![]() Presumably, like me, your serving transmitter is Tacolneston...... am I correct in my findings that freeview HD won't be available until after the November change over ? Thanks |

Thanks This recorder is getting a bit long-in-the tooth now so I'd be surprised if Panasonic were still giving it active support. I've been thinking of changing to a combined hard-disk and DVD recorder. It would save some space and give me some more modern technology. |

It would save some space and give me some more modern technology. I only use the ES20 as a backup if we need to record more than 2 programs (also have BT vision) ...... This site http://www.ukfree.tv/shutdowndetail.php?tx=TM131958 suggests that soon after changeover the transmitter power would be increased and I read somewhere that HD would start soon after..... |

Thanks for the link David. Some interesting information and further links.
I rarely record using the ES20 and, like you, almost only use it as a recorder when I need to record more than two TV or radio programmes at the same time. There is such a bewildering range of equipment on the market at the moment that it's difficult to decide what to buy. |

In regard of the modern twin HD tuner recorders, you may find 'this' explanation of the range useful.. and details of the way they work which is somewhat different to previous methods.

It's the final big switchover day here from the rowridge transmitter (at last) and I was reminded of this thread as I rescanned our various boxes - happy to report that not only is the ES20 still soldiering on, it only needed one scan today!
Perhaps it was the presence of those pesky old analogue channels that was confusing the software previously... |

Hi all, sorry for hijacking an old thread, but I'm trying to return a friends DMR-ES20D. The DVB version is 1.08 (I realise this may be very old!) and when I try an auto setup restart, it sticks at Channel 50 then seems to give up. There is a message on the display that says 'U80' whenever I scan, or try to do a software update search now.
It plays DVDs great, but I'm trying to get the Freeview recording function working. Am I wasting my time? Cheers!

Hello everyone! ---WHAT A GREAT INFORMATIVE FORUM---
I am having real trouble with my es20 it tries to tune in but it gets stuck at 58 (on the frequency band).... I have tried the reset as well as the wait 10 mins with it unplugged but still no luck. I am even having trouble trying to get the update to see if this as any affect! I am not sure if it a hard ware or software problem... i may even look at the caps to see if any are O/C. has anyone got anyother ideas! |

They fail in a variety of ways and that sort of failure is extremely rare. Neither can you reliably detect a failure by measuring its capacitance. I can probably direct you to all the caps that are suspect in this machine but it would mean you dismantling the machine and providing some decent pictures... so that I could identify the likely caps that will be causing this particular problem... which is likely due to a combination of failure of a cap on the main board and possibly some on the tuner board.. backed up by a number of caps in the power supply - which if you are going in to replace are best done as a complete job - which probably means replacing 5 to 10 caps. The EH60D is the sister machine to yours - so you can get a feel of it here. It is more or less the same machine as the ES20 - but with a hard drive. But there are differences - especially in the tuner so I'd need a good picture of that. So - I don't know if you want to take this route or go to this trouble - but advise if you do. |

I am not sure if it a hard ware or software problem... i may even look at the caps to see if any are O/C. has anyone got anyother ideas! I have recently sourced a second hand DMR-ES20D, and I have exactly the same issue, except that it gets stuck on channel 57, at which point the front panel indicates a U80 error. Having googled extensively over the past few days, I now admit to being confused. 1) Could this be caused by an old firmware version? My DMR-ES20D reports that it is on version 1.08. I sourced a file from a Panasonic website which which stated it was firmware update U3-161 suitable for DMR-ES20K and DMR-ES20S. (Not DMR-ES20D)... I burned it to CD according to the instructions, but the box rejected the update with the "UNSUPPORT" message on the front panel. Is this because the model number is different? or because 1.08 ia already the latest firmware for the ES20D? 2) Is it a hardware fault? I opened up the box, expecting to find at least some caps showing signs of stress. However, every single cap in the box has no leaks, and no doming whatsoever. Of the indicated problem caps... (from another thread relating to the EH60D) PSU C1270 - 1500µF @ 16V 105°C C1271 - 1500µF @ 16V 105°C C1272 - 1000µF @ 10V C1607 - 680µF @ 10V 105°C C1707 - 680µF @ 6.3V 105°C C1406 - 680µF @ 6.3V 105°C Main Board C1518 - 680µF 6.3V 105°C Tuner / VIF Board C0701 - 1µF 50V 105°C C0703 - 1µF 50V 105°C C0707 - 0.47µF 50V 105°C C7839 - 1µF 50V 105°C ... They all appeared to be Panasonic branded rather than the ELNA brand which others have reported. There does not seem to be a C1518 on the main board, of this capacitance, so I guess in this respect the EH60D and the ES20D differ. I am aware that electrolytics can fail without physical bulging, so... Do I replace the caps? All of them (listed above)? Should I replace the caps regardless of having a firmware update from V1.08? ...or can I source a firmware file from somewhere to try before dismantling the machine further? Will the machine operate with Freeview at all with such an old firmware version? I'd be most grateful for any insights. |

There is no further help, and no firmware on the panasonic UK site. |

Ah well: in the past I've always found Panasonic UK Customer Services (see Contact Us on the page I mentioned) to be very good at responding to phone calls and web contacts.

I have requested a link to the latest firmware update, resulting in a response some 30 minutes later that the request was "complex", and had to be routed to a specialist. Why Panasonic UK can't host these files for download as they do in the US, and other countries is a mystery. |

The 'unsupported' message indicates that either the disc is not a supported format ( Note that it should be a CD - not a DVD) or the file format is wrong (unlikely here) or that the disc is dirty and cannot be read. But all of that doesn't matter because the you are attempting to put the wrong software onto the machine. It has to be for the ES20D. So if you overcame this 'unsupported' problem you would run straight into another. |

Good News
Panasonic sent the disk to me, with the 8.13 firmware update.
I used it to update two DMR-ES20D machines, one previously on version 1.08, the other on version 1.11. Both of these machines halted with an error U80, when scanning for new digital channels. I'm happy to report that with the 8.13 Firmware installed, both machines now scan to completion and find all digital channels perfectly. No new capacitors needed. No Soldering required. Thanks to everyone for their advice. |

We've got the ES20D updated with 8.13 firmware a month or two ago.
Just noticed it doesn't have Drama or anything after it on SDN multiplex list. i.e. 5Later, BT Sport Preview and True Entertainment, VuTV and PeaceTV Seems like there's just too many largely useless channels on SDN for the Panasonic to cope with. The good news is TopUp TV is closing at the end of October so that'll get rid of 5 or 6 channels. P.S. the ES20D seems to be behaving itself apart from this. |

The DMRES20D is still missing Dave Ja Vu and Drama. They are the 33rd and 34th channels on COM4/SDN. The machine only registers 32 channels on the multiplex.
I emailed UKTV saying they should ask to have the IPTV portals moved to bigger numbers on the PAT table.

UKTV got back to me, they say they have spoken to Arqiva about this issue and that Arqiva are now investigating the technical aspects of making changes.
I am thinking that changes may not happen if it requires a retune, but the principle seems to have been accepted. |
