A close look at the circuit board revealed a swollen C1530 (a 100uF, 25V electrolytic capacitor) which gave me a clue about the area involved. A look at the schematic in page 48 the service manual (I got this from ftp://wolf170571.dyndns.org/C%EF%F0...Panasonic/Panasonic_DMR-EX75EG,EX85EG_dvd.pdf) gave me a clue that the IC1508 voltage converter may be the culprit. IC1508 converts the 12v rail voltage to 1.8V. The 1.8V output should be present on Pin 7 of connector P7413. It wasn't - only about 0.1V was present. 3.3V on pin 8 and 11.6V on pin 10 were present though, which told me that the 12V supply rail shared by all the voltage converters/regulators was OK. I therefore decided to replace IC1508 and the swollen C1530. It also seemed a good idea to change C1533, which causes the 'no Freeview' fault. Of course, it may be possible that the U81 error is caused by something else, so if you have the problem it's worth checking the voltages on connector P7413. The following pictures show where the connector is. Last edited: Jul 16, 2011 macklij,

Category:Consumer Electronics Share this conversation Expert: Louie replied6 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 error code u81 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 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 L
