Question about Panasonic DMR-E80H DVD Recorder
Self checks for too long
A self-check for these models can sometimes last for 3-7min's (sometimes longer) depending on how much recorded data is on your hard drive. Plus it checks all unrecorded space on your hard drive as well. Don't forget that it must check 200Gig. If it self checks for longer than 20-30mins turn off at the wall and let cool down. Try again in an hour or so and it should rectify itself. If it continues to self-check for longer than 20-30mins refer your machine to an authorized technition

This can usually be down to two things, a faulty PSU board which is going to be expensive and needs to be professionally repaired, or simply a faulty or dirty DVD has been inserted into the machine.
Try the following:
1. Hold down Standby and Eject buttons on front panel together for 60 seconds (until the recorder goes into standby mode).
2. Now hold down Eject button until it ejects the disc.
3. Now insert a different DVD disc and see if that cures the problem.
If that fails then it's probably a faulty PSU, and unless the recorder is under guarantee or warranty it will be too costly to repair.

My DMR-EZ47V was displaying error U61 after developing a fault while trying to load a disc. It seems it is sensitive to some brands of disc. I managed to get the disc out and after that it instructed press OK button. On doing so it ejected disc tray and switched off. Subsequent efforts of switch ON/OFF just came up with the same failure. Eventually after placing a known good recorded disc it managed to recover and return to normal.

Ok guys, you asked for a fix for the DMR E55 Self Checking cycle. Here goes.
In 99% of cases this is caused by a faulty regulator on the main power board. The power board is located on the right hand side of the unit. The regulator is IC001 which is mounted on a thin metal strip which acts as a totally inadequate heatsink. This means that this component constantly works at temperatures beyond its tolerance. Because of this it usually lasts a couple of years and then starts causing problems. The Self Checking syndrome is typical. If the regulator burns out completely, it can take other components with it, blow fuses and scorch the circuit board.
If you are competent in using a soldering iron with care, order an STRG 6353 regulator. These can be obtained online from a number of suppliers. Disconnect your DMR E55 from the power source and remove the lid.
Next, remove the fixing screws from the circuit board on the right where the regulator is located. Carefully remove the multi connector on the left side of the board. Remove the screw above the power connector on the rear of the unit. The power board can now be removed from the cabinet. Using a small pair of wire cutters, clip all five pins from the old regulator as close the the top of the board as possible. Undo the screw securing it to the heatsink and remove the old regulator which can now be thrown away.
Next, using your soldering iron, remove what's left of the pins from the printed board and with a solder sucker or desoldering braid, clear the holes ready to accept your new regulator. Be careful because if you over heat the print it can lift away from the board.
Use a little heatsink compound on the back of your new regulator, poke the pins through the circuit board and then secure it to the heatsink. I usually fit an extra heatsink on these units which helps to reduce heat and prolong the life of the new component.
Next, resolder the 5 pins on the print side of the board. Use a magnifying glass and make sure you haven't missed anything or bridged connections in error and caused short circuits.
Now put the board back. This can be a little trick but it's easy enough if you take care. Replace all the screws and carefully reconnect the multi connector.
If you have followed this correctly, switch the unit back on, pop in a DVD and give it a try. Unless you are very unlucky, You DMR E55 will no longer repeatedly self check and will operate correctly. Whilst it saddens me to hear that some of you guys would toss your DMR E55s into the trash can for such an easily repairable problem, please do not attempt this unless you are confident in your own ability.
Finally, do check that the fan operates but remember it is temperature controlled and will not activate until it is needed. Do not assume it is faulty because you do not see it working straight away. I have repaired lots of DMR E55s and I have never found a single fan or fan control circuit to be faulty. That's not to say it can't fail. good luck...

Manually pull down the front shield, then somewhat forcefully pull down the inner shield and maybe two little white pins so the tray is exposed with nothing blocking it. Have someone plug the machine in while you are holding everything out of the way and the tray should start to open. Pull your fingers out quickly so you don't block the tray from sliding out.
