The MD5001T is used to generate 1.8V (core voltage?). It was reasonably easy to fix: desolder panasonic dmr ex75 problems bad caps and 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 Ex75 No Freeview
what ther error code U81 means and how to fix it? I came back from holiday the other day to find my machine displaying U81 and having not recorded a single item that I had set it http://blog.spitzenpfeil.org/wordpress/2015/10/19/error-u81-panasonic-dmr-ex75-repair/ 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!

Couldnt find the 1 other post until i my account was validated so i could'nt do a search to find it ( as its not directly related to it) My machine is 6 days old and displayed it. Machine locked up whilst watching Freeview. Rebooted , and displayed U81 rebooted, took ages to come back up.. working ok....but for how long before it does it again. Be nice if there was an actual reponse for what U81 actually meant. chipuk View Public Profile Find More Posts by chipuk 25-11-2006, 12:58 #4 Munchkinn Forum Member Join Date: Jan 2005 Posts: 341 http://www.digitalspy.co.uk/forums/showthread....

Mine hasn't done it since - but then I haven't left the machine to itself without using it for longer than a day. MattL76 View Public Profile Find More Posts by MattL76 26-11-2006,

Category:Consumer Electronics Share this conversation Expert: Louie replied6 panasonic dmr years ago. Hi and welcome to JustAnswer,Initially, error code "U81" indicates a microprocessor issue or it fails to communicate with any one of the devices it controls/monitors. It is a hardware fault.Offhand, if have not been tried, power off, wait a minute or so and power on. It will perform a self diagnosis. Should the error code persist, perform an ATP re-execution by pressing CH UP & CH DOWN simultaneously for 5 panasonic dmr ex75 seconds.Should the above be not corrective, Options then are: consider a DIY (do-it-yourself) repair if and only if comfortable working with electronic components & circuitry, use of a DVM/VOM, a soldering iron/station and safe practices with electrically powered devices. Access to a Service Manual or at the very least, a schematic diagram would be a necessity;should you be uncomfortable with a DIY, perhaps your best bet would then be to consult with and/or seek the services of an authorized Service Center or a qualified professional;evaluate other options considering cost of repair, down time, cost of shipping, parts availability and comparable prices of newer/better models.If a DIY is being considered:Service Manual is available here;ensure that the back end PCB is seated correctly;ensure that the connectors and FCCs are seated correctly at the paired RAM & Digital PCB modules.Good luck and thank you for asking JustAnswer.Edited by Benimur on 5/13/2010 at 8:27 AM EST Louie and 3 other Consumer Electronics Specialists are ready to help you Ask your own question now Share this conversation Related Consumer Electronics Questions Question Date Submitted My Clarion The touchscreen stopped halfway out and will no 10/14/2016 10/14/2016 Richard Bought new, tv.need need to progrmaremote 10/14/2016 10/14/2016 Jack I have a Panasonic plasma tv that I just put a main board in 10/14/20

The U80 or U81 that has been displayed is a self-diagnostic fault code, this would require the attentions of a Panasonic approved service repair agent. It also can indicate a weak signal. This is not an inherent fault with the product but a guide for the engineer to know where, within the product, he should seek the cause of the problem. With either of these error messages the aerial may need an adjustment or possible upgrade. During the EPG download, if there is noise on the data lines due to poor signal, the unit can go into U80 or U81. Back to results Was this answer helpful?
