Dave, great series. I hope your viewers realize and appreciate what you're trying to exhibit while doing this. Not only do you know your electronics, but have exceptional mechanical ability as well. It's too bad everything is made to be thrown out today rather than repair. I purchased my first Betamax from Sears around 1983 or 1984. It was a top loader and the first recording was a Three Stooges short! Blank tapes ran about 10-12 bucks apiece. I'd buy one a month! Thanks for your tutelage! BTW I was an electronic tech for 20 years and now repair and restore Vacuum tube equipment as a hobby.

Thank goodness for the invention of the internet, youtube, and people like you. I have a Panasonic E85H. I have enough basic knowledge and equipment to check electrolytic caps. But no oscilloscope, etc. After a power outage my unit was dead. My caps were good. So, I ordered the same component that you replaced, and it came back to life! Thank you very much!

I have to admit it's a pretty cool machine, I kinda want one now. Excellent job on the repair

I can’t believe this video exists! My DMR-EH50 has the exact same problem, and following along with the troubleshooting steps, it seems the same MR1521 IC has gone bad. Just ordered a replacement from KP Components and am hoping for the same result. Many thanks for taking the time to produce this!

Had a DMR-EX85 (250GB - single tuner Freeview) for many years caned on daily time-shifting duties. Always liked the caddy system as is felt solid and reliable..and also because it reminded me of early CD-ROM drives! Upgraded to a 500GB Panasonic Blu-Ray recorder (twin tuner Freeview HD) in 2015. Also took the opportunity to 'upgrade' our 720p Panasonic plasma to a full HD Sony LCD..although, yes, I do miss the plasma!

I used to have the Samsung R120 from around 2003 or 2004. Mine didn't have a hard drive in it though. That one could record on ram discs as well. Used it for many years until I started to get into Blu-rays.

Can't remember the model number or the make but remember buying a DVD recorder back in the early 90's, worked great but it had a major flaw, would not record almost anything as the broadcasters starting sending a signal through that would disable the recording capability. So pissed, because it was just a excellent and reliable recorder.

If you're looking for a good set of micro screwdrivers check out Wiha 26197 made in Germany and the set is around $20. I've had mine for years and I can confirm that they definitely won't break in half when repeatedly dropped onto a concrete floor :-). It's a shame that the bit was that brittle usually you want strength AND flexibility in a screwdriver bit looks like it had one but not the other.

I have owned DVD recorders from Toshiba and Samsung, and a camcorder from Hitachi that recorded to DVD-RAM discs. Compatibility between the various devices was good too.

Hard to say. Could have been a set up too. The new Mayor has been targeting businesses lately. Say for example he has a business license to operate an office out of his house as I did. The business license is very specific that it states that no clients are permitted. I had to pick up and deliver all the work, or have it shipped in. I was permitted to operate a home based office only. It was a tax grab basically, because what I do in my house should not be the cities business. If you are an app developer, editor, graphic artist ect. they want their cut. Even this youtube production thing they want their cut. In his city recently, the mayor instructed bylaw officers to book Uber and Lyft rides, because the Mayor did not want either ride sharing company in the city, even though ride sharing is provincially regulated. He was protecting the taxi industry that voted him into power. The bylaw officers would book rides in city limits and when a driver showed up, they ticked the uber driver over 500 for operating in the city without a business license. A business license that is not available. It wouldn't come as a surprise at all if the bylaw officers called to order a part and asked if they could pick up, and he said OK as he used to for me and a few others that were buying parts from him. He would always say, something like I will be available only today before 3 or between 2 and 3 or whatever hours he felt like, because he did not have a walk up counter that anyone could just show up. So it wouldn't not surprise me if they set him up posing as a customer and when he opened the door slapped him with a fine, and then used the lame excuse that a "neighbor" had complained. We have a few sleazy bylaw goof balls here too. I one day stopped my company truck at the side of the road, was sitting in my truck writing down a new contact phone number. A customer had called me while driving and I had taken the call on my hands free. So I pulled over to write the details. I no sooner stopped and the "parking Nazi" knocked on my window and wrote me a ticket for 143.00 for "standing, stopping or parking" within 2 meters of a driveway. My bumper was less than 1 foot past the yellow line. Naturally the company would not pay this ticket, so I lost about half a days wages because I stopped to take a note.

@@12voltvids ....I understand about the taxi situation. In the states, taxis have to pay fees, licensing, city fees etc. and medallion fees... Whereas, Uber and Lyft don't have to pay any licensing fees or anything to the city, so it not a level playing field since taxis pay so much money in fees and licensing etc. So on that regard I agree with the city laws ,in fact ,they (uber lyft) are able to undercut the taxi rates because they aren't paying their fair share of fees.... That would be like two repair shops and only one has to pay fees,licensing, taxes etc, and the other is given a pass, that's simply not right... Hopefully you get my drift, I'm saying all of this because after I got out of the electronics servicing, I had driven limo for a couple years, and we had to pay all the same fees as taxis Hence the taxi and limo commission who enforced those fees, whereas uber and Lyft paid absolutely nothing in fees and in turn would undercut everyone's prices but didn't have to pay or play by the same rules as the taxis and limos. We paid, they didn't.

@@frankpitochelli6786 Exactly the same here. For uber and Lyft the government requires that all drivers have to have a class 4 license which is a taxi or limo license. Opposition wanted just a regular class 5, but the government insisted that a class 4 and uber / Lyft have to have special insurance. Plus unlike other jurisdictions their minimum pick up fee and per mile fee is set. So the playing field is a little more balanced. It took 7 years to get here with push back all the way. The current government promised it in the last election and the delivered but made it pretty restrictive as to not kill the cab industry.
