It's quite apparent that you can't touch anything that's at mains potential,"   That's poor English. Obviously you can touch anything that's at mains potential but you shouldn't.

jurb6006@gmail.com: Nov 23 03:06PM -0800 Working on a scope here and as you (should) know with no input there should be a flat line. Ground reference, ant V/div. it is there. About 50 KHz all over it.   Then I move the bench light, on the arm y'know. It gets bigger and smaller. You S O B !   Couldn't find a regular incandescent. I DID find a halogen that screws into the same socket. It is much better now but the other lights overhead are CCFLs so I dunno about changing all of them because they get left on all night sometimes and there are a bunch of them because I am still half blind even with 20/20 vision. It's a retina thing, not to mention a polluted vitreous.   Anyway, I bet LEDs have some sort of DC DC convertor in them eh... Probably those classy precision instrumentation quality Royers right ?   Fuck.   Green ? Maybe I'll go out and bury a bunch of used lytics...

Changed to using an LED bulb about a year back and problem GONE !!!   Extra plusses are that the LED is plastic so not fragile are brighter and give better colour rendering.   I think the difference must be is that while both lamps employ high frequency inverters, LEDs run at low voltage while CFL tubes run at high voltages - so radiate a greater electric field and capacitance couple much more.       ....

What did you do to fix this problem?   Ich have an DMR-E30 with a problem very equal to your problem. It goes on, does absolutly nothing, if I press the off-button for 10second it show "BYE" in the VFD and switch off.   I know that the powersupply is working. The maincontroller can write "BYE" to the VFD so I know the controller is working. But when I close the testjumper it did not show any error-value. So my guess is that it is a problem with the firmware in the flashmemory and I guess you have the same problem.   Olaf   p.s: I am graduate engineer and professional hardware developer and I have the repair manual. But this time I think I have to give up. It is a shame, because this old recorder is a masterpiece!

jaugustine@verizon.net: Nov 16 07:32AM -0500 <SNIP> >thing.   >Go back and read the previous thread, maybe there is some help there.   > Michael   Hi Michael,   Here is one of the replies I received in that previous post from a "Lee":   "Yes. Bad capacitor. Replacing it fixed it"   I asked "Lee" which capacitor? He NEVER responded.   John .

John-Del <ohger1s@gmail.com>: Nov 16 07:44AM -0800 > I asked "Lee" which capacitor? He NEVER responded.   > John > .     He may not have made note of the cap. I don't make notes unless the problem was something that took a lot of time or was really non intuitive (like a 100K leakage on one of the front panel switch contacts - yep, had one of those recently)   And you assume that *your* recorder has the same bad part as Lee or someone else had the exact problem as you? It might, but it doesn't have to be necessarily. What if he told you the location and that didn't fix it? What then? I've seen several problems in these Panasonics cause the constant 00000000, including my own DMR-EZ475V.   I already told you that the constant 0000000 on ac plug-in means incomplete software loading or corrupt software. If the software isn't corrupted (I haven't seen a Panny do this), then you have to figure out why it's not finishing the boot. You're an experienced tech and the manual is on line. What more do you need? It's not like it's intermittent.   BTW, you can buy a working example on ebay for like $60 U.S.

olaf <olaf@criseis.ruhr.de>: Nov 15 07:37PM +0100 >How? If you're going on that it's outputting voltage, that only proves the power supply is not dead, but that's not enough. I've seen these sag and recover so quickly that you won't see it on a DMM.   But I think I would see it with my 200Mhz HMO2022. .-)   > I repaired several of these Panasonic recorders with a cranky smps or > buck converters that refused to complete the boot.   I agree, if someone would told me anything like this my first thought would be the power supply, too. But I checked it VERY carefully.   But sometimes, only sometimes it is not the power supply...   Olaf

frank@invalid.org: Nov 17 08:44PM Hi all, I'm restoring a couple of 1970's wooden case acoustic coupler, both made in the UK. I haven't find the slightest bit of information about both of them, just some pictures on the net. One of them is the DCD model AC.350.OM (where probably OM stands for Originate, as it doesn't have any Orig/Answ switch). Now, I'm checking most parts (it's made on 6 PCBs, plus some chassis-mounted components) for obvious problem, like diode/BJT junctions, carbon composition resistors values, electrolytic ESR/shorts etc. All transistor have MAxxxx or MExxxx codes, they really look like BCxxx transistors from the early 1970's, one of the most common ones is ME4101. By the way, the ICs have 1972-1974 date codes, so this unit was probably manufactured in 1974. My first question is: does anyone have a cross reference for these MA/ME transistors? Are those a kind of military markings? Second question: almost all ME4101 have a junction voltage drop around 0.8V but one of them shows a bit more than 1V drop on both BE and BC junctions (it's NPN). Can I assume this one must be bad? Any other hint and information is welcome. Thanks Frank IZ8DWF
