What Does Panasonic Error Code U81 Mean
hotair station — BLDC Fan-speed mod → Error U81 -- Panasonic DMR-EX75 repair Posted on October 19, 2015 by robert Some explanation: The cause: many dead electrolytic capacitors + blown DC-DC regulator. The MD5001T is used to generate 1.8V (core voltage?). It was reasonably easy to fix: desolder bad caps and panasonic dmr-ez47v error code u81 replace, desolder SOIC-8 IC and replace. Done. The only caveat: the PCB is a single-sided phenolic one, so no plated holes! The traces lift extreme easily, watch out! The device is very modular, which is good. Nevertheless I had to remove every single PCB, the DVD drive and the hard-disk to get access to the underside of the large circuit board. A few things surprised me: Apparently it is still cheaper to have a single-sided phenolic board and be forced to use a "wire-jumper-machine" than to just order an ordinary 2-sided circuit board. The large black connector that goes to the "brain" (HDD-controller, DVD-controller…) is unpolarized! Once the device is more or less assembled, there is no way to connect it wrong (no space), but during debugging… one could plug it in the other way.

Panasonic Dmr Ez25 Error Code U81
Date: Nov 2006 Posts: 4 DMR-EX75 Error: U81 Hi All, Does anyone know what ther error code U81 means and how to fix it? I came back from holiday the other day to http://blog.spitzenpfeil.org/wordpress/2015/10/19/error-u81-panasonic-dmr-ex75-repair/ find my machine displaying U81 and having not recorded a single item that I had set it for! Panasonic tech support just gave me the usual response - but I don't really want to send it away if its something simple. Why won't they just say what the error code actually means? Thanks in advance!
