Reinard Synth#16 Roland XP50 No Audio... Dead DAC?

An episode about the Roland XP50 where I initially thought that the Digital to Analog Converter (DAC) was broken... I was wrong... As for a lot of Roland synths of that time, the smaller 10uF and 47uF SMD electrolytic capacitors started to leak, cause damage and... no sound out of the DAC although the DAC itself is perfectly ok. Anyhows: a video on how I discovered what was going on and how I repaired it.
If you want to recap the board you will need the following capacitors:
- 16x 10uF/16V SMD Mouser Nr. 667-EEE-FC1C100R
- 6x 47uF/16V SMD Mouser Nr. 667-EEE-FC1C470P
- 2x 330uF/35V SMD Mouser Nr. 667-EEE-FC1C331P
- 4x 100uF/35V SMD Mouser Nr. 667-EEE-FC1E101P
You can also use normal radial caps with the above values.
Incidental music: Me and my Yamaha Montage.
Tools used:
- Steinberg UR22mkII + Audio technica 2020 for voiceover,
- Sony ZV-e10 as video camera (4K segments) Olympus E-M10 for the older HD segments
- Manfrotto Magic Arm
- Editing: iMovie (Easy bits) + Davinci Resolve (difficult bits)

SynthFixShort#9: Virus TI Display backlight repair

Most often the backlight of the display as used in the Access Virus TI and TI2 dies. By simply replacing the LEDS with new 3mm ones one can repair it and enjoy the TI's display... This display is impossible to get new nowadays. A couple of years ago I managed to get a bunch from Arrow.com (see link below), but they don't have them anymore. I did this modification on a non-working Virus TI displ...

Ever had one of those projects you cannot solve and are working on and off on? Here is one I had: Repairing a non-booting Lexicon PCM90... Finding the reason it did not boot was ... convoluted to say the least. Solved it, but then new problems popped up. In the end I have a fully working PCM90, but I did learn something which this whole episode is about. Hopefully it is of use to you. This vide...

This time I rejuvenated a Korg 01/w pro by giving it a nice LED backlit LCD, a new felt to make the keybed less clacktiyclack , replace some key, replace all front panel switches (almost standard operation with my repairs...) and some other small bits and pieces to make it like new. Especially the contrast range caused some head scratching, but I think I nailed that one as well. Display used: w...

I have a Korg i30 on the bench this time. The user interface works just fine but... no audio? Finding the culprit was easy and luckily I had the appropriate spare parts (a M5216L OpAmp and two 2SC2878 muting transistors). Got it in full working order again, and has already found a new owner as well. A note on the 5216 and muting transistors: They are not produced anymore and hard to find which ...

This time a Roland D50: came to me with some weird behaviours: locked up when pressing some specific front panel buttons, sound only when releasing a key... hmmm...

Переглядів 1,3 тис.Рік тому

I bought two Roland FP8 digital pianos to make one working out of them. Discovering leaky caps in the audio output circuitry was one thing, but the hammers repair was a lot of work. Did I mention that the FP8 is $%&# heavy? No? It is bloody heavy... Anyways, repaired the output circuitry and the hammers, and along the way also made a new slider fit the existing slider cap. Have fun! I did use s...

I bought this M1r as “working but with distortion on the audio output”. it turned out to be a missing capacitor on the power supply! It was mounted badly during a previous repair, but I fixed this... After fixing the Power supply I also replaced the green LCD screen with a nice "White on Black" LCD display. I used one from BuyDisplay which can be bought directly from their website: www.buydispl...

Just a quick one on a Roland Juno-2: Keybed issues... (#3 in my top 8 of synth faults btw...) Rubber domes based contacts are not my favourite keybed contact technology, but what can you do? Other than occasionally clean them... As I did here: A Juno-2 came to me with a couple of keys not working... fixed that... also note how I determined that it is a keybed contact issue at all by the way... ...
