Panasonic Dmr Ex75 Factory Reset
memory lane YOUYUE 858D+ 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 panasonic dmr-ez47v error code u81 fix: desolder 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. DMR-EX75 U81 issue on avforums DMR-

I panasonic dmr 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 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 panasonic dvd recorder in advance!

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.

Search for - error, code I used to be able to turn the unit on and then after waiting for a while, turn it on again but unable to do so this time so might give it a miss and throw the unit away. How can a company as big as Panasonic make a recorder with this common fault all the time especially when we get a lot of surges in WA. Very disappointing! Rosemarie June 2014 I've just been given one of these DVD recorders with the same error, U81 (UART error) which I've now fixed. The problem is caused by C1530 (100µF 25v) on the Main PCB. This blows (open circuit), causing IC1508 (FET dc-dc converter) to fail. It's a tiny SOP-8 SMD on the underside of the board. This IC supplies D1R8V from the 12v line to the STi5516 processor board. Replaced the cap with 100µF 50v and cut and replaced the IC (MD5001T) and all works fine now. You'll need to strip the whole box down to get to the parts, and be careful of static wrecking parts of the board. The story about wrecking the "Freeview Decoder Microprocessor" is frankly rubbish - unless it was wrecked by the engineer doing the repair. Cost? About 1-2 pounds if you can get the parts. Richard Lee August 2011 I've taken mine in for repair to a local independent. It's not good; One or more capacitors have blown and they've taken out the Freeview Decoder Microprocessor which has to be ordered in. As at 19 April 2011, the repair costs are likely to be around £60-80 Colin M.
