excellent diagnosis and great explanation

Hi Michael, i have the very same fault on a samsung tv ue46es8000u so this is where i need to look?

Bloody Brilliant Thankyou so much SIr! from Brisbane Australia

Excellent work

That's a really good picture. I usually find they gave rather flat pictures compared to other sets of the era.

My Samsung start button doesn't work and I have not cooked the Christmas cake yet erhhhh

Absolute text book Michael. Thank you. Also a clear explanation of fault finding. One day perhaps I'll be brave and have a go ! Loved the milli Ohm meter approach

great video mate, im in my mid 20s and i have really gotten into vcr repairs, first is was cassette decks but i do both now, i have a teac mv550 in my hifi stack of black Teac components that i use to record music onto, its a 4 head with hifi stereo and has all three tape speeds. i have fixed about 20 vcrs so far. i also go a sharp vc-793 which is built like a tank, even got the remote for it, needed the idler reconditioned but other than that its fully working.

It is not possible for me to know what you are doing. You say "I unplug that" while not showing what "that" is.

👍

Enjoyed it. Good old reasoning. Would add some warnings though. The power supply board can store dangerous voltages in the caps.

👍👍👍

Your a master of fault find and solutions.well done

Could be moisture ingress causing the leak? And if it's been standing for a year, any moisture would have evaporated probably.

That was an L of a mod Michael 😂 (sorry, had to). Absolute wizard of an idea though. Still the master !!

funny how the warranty runs out the day before it breaks down,,Michael theyll be paying not to make these vids lol 👍

Not sure quite how you figured out what the problem was, but nicely done. You could have bent each of the five retrofit diodes into a "Z" of sorts before fitting them, which would make access for soldering a little easier.

Very good fix .Cheers from Australia.

Another genius workaround from Michael. The fact that the display is no longer available shows the high failure rate. Samsung gear is not what it used to be.

Well done Michael you are a clever chap who certainly don't give up easily, I really enjoy your videos and learn a lot. A while ago I spent some hours investigating a similar non start Samsung Microwave. Not having the circuit or knowledge of relay operations etc I tackled it by visual inspection, re-making various soldered joints, substituting a start switch and latterly substitution of a couple of relays. At some point it started to work again - but not reliably. On days when it failed I left it unplugged overnight and if it worked the next day I would carry on using it on a daily basis until it failed again. Eventually it fixed itself so I was left wondering what was the cause of the problem and expecting the problem to return. I believe in a previous video you mentioned it might be connected to leakage from the display. So when it was not in use I have been disabling the display by pressing the Eco button. I will check to see if the display has ghost L's but will dig out and fit the diodes.

cool!

wow that was a great piece of diagnostic work, a shorting out display causing it to go into a lock mode ,the clues are there , thanks Michael😊

Well done Michael - good fix

Thanks sir❤❤

Nicely done Michael. What lead you to this (correct ) guess ? I know decades of experience (same as me in IT), but was there something in the past? To me this is almost like an early start to the Royal Institution Christmas Lectures :) So Happy Christmas too, just a bit early .

excellent tutorial! very well explained....thanks

Hi Michael, nice to see such vintage collection. Do you know if I can buy such old RS catalog somewhere for a marketing event? Thank you.

8% VAT in 1981. They abolished the 15% rate in 1979. With the arrival of japenese sets and decreasing prices of electronics and higher integrated electronics bringing down the prices, the rentals business model was doomed to fail in the UK. I remember a black and white PYE we had that ran for years, and various models of Grundig, ferguson and Thorn EMi sets rented from radio rentals. We always used to have a guy that used to come out and try to fix them by repatedly tapping the boards in the TV with the blunt end of a screwdriver, but always used to take them away in the van. I don't recall him ever fixing anything on site. I supposed this is why people rented, because if anything went wrong you just got another to replace it.

Great Video! Dear Michael, would a Denon RCD-M41 (made in Japan) - Power Supply markings on back of unit : 100V ~ 50/60Hz work safely in the US? That is - would the Denon Power supply and components handle the US voltages without having to use an external voltage converter? Cheets

Bosch/Siemens/Neff ist Qualität! Diese Geräte MUSS man am Leben erhalten! Weil sie den Billigschrott von Bauschlecht u.s.w. überleben werden!

Great tip.michael. thank you

Hi Michael, thank u for your video. I have the Denon RCD M40, whenever I turn it off for too long (about 4 hour or more), it would not let me turn it on again, no light on the led. it happen using the power button and also by remote control. Until I unplug the power cord and replug it again, then I can turn it on normally. Could u please advise me what have happen with it?

Most of you guys say the same thing, either the backlights are working or not, so replace the backlights if there not working. But not how to definitely tell if it's the power supply and not the back light.

God...way too much dribble not enough meat.

I now know just enough to know not to try repairing one.

Thank you, great work! Worked on my Samsung MU617!!

I started repairing microwave ovens in the early 1980s and got out of it just as the inverter ovens came on the market. With the fake parts, not all of them have sanded surfaces. When semiconductor manufacturers reject parts that don't meet specification, they divert them into a bin and these get sold off as scrap. They are diverted before the markings are applied so they look new and genuine, just with nothing printed on them. Unscrupulous dealers buy these parts and print whatever numbers on them they want so you think you are getting the real deal but in reality the device could be anything.

the last magnetron I had from magsells kept overheating and logging fault codes, bounced twice, could never get it to do it in the workshop. It had alot less fins than the original

Deutscher Titel, deutsche Beschreibung - für ein englischsprachiges Video? Was soll das?

Please how do you get the panel. My Samsung micro have the same issue. Thanks

Great another video,

No help with striation on left? Damn

I loved ETI !

Do you have a link to the inverter board schematics?

Dear mr Dranfield, would it be possible for you to explain the working of the device you use to reform capacitors (as visible around 13:50) ?

Great video Michael thanks for the information and for the substitute part !

Thank you for sharing your extensive knowledge !

When the first Panasonic inverter microwaves came out we were told not to try and fix them but we had to send the failed boards back to Panasonic

Could you do a follow up of WHY that missing earth turns the microwave into a useless metal box? Intriguing. Love your videos and your knowledge Michael. Thanks for your help!
