Thanks to all who posted information regarding repair options to Panasonic DVD recorders. A newbie, this is my second post.
I came across this site in my research about DVD recorders. I just joined the forum in order to get in touch with MickinCT to see if it's worthwhile to repair my non-functioning Panasonic DMR-ES20, a 2005 model which, based on what I've read, is showing those same signs and symptoms which others have reported, namely, the disk tray won't open (no disc is stuck in it); I get the self-check set of zeroes going on perpetually without putting the machine in a startup mode; or the clock flashes, but the machine won't go into a functional mode.
Since I am unskilled repairing such units myself, I need to rely on an expert to tell me if the unit is salvageable, or if the motherboard has become totally defective over time, rendering the recorder unusable. I don't have any interest in buying a new unit, but, if this Panasonic can be rescued, then I'd certainly like to explore that option. These DVD recorders are great machines, not only for recording broadcasts, but also for archiving VHS tapes, most of which I have not yet converted to discs
I appreciate the recommendations that MickiinCT is the guy to do the job, so I would like to get in touch with him to see if the unit can be repaired, as well as at what cost.
