      Wow, in awe of how you do open heart surgery on these radios… and all the conversation replies, it’s like a new language to me! Hoped to see why my almost identical radio (hardly used) won’t switch on at all. Was parked in the guest room, on battery power but not mains. After a while saw the red dot sb light had gone dim. Changed the batteries, also plugged in, but dead as a dodo. Anyone think it’s fixable? Thanks

    This is 'Right to Repair' in a nutshell, all we ask is that companies make the parts available at reasonable prices and we'll do it ourselves, great work and interesting video....cheers.

    Nice save of what appears to be a quite nice radio. Kudos to Roberts for their remarkably reasonable spare parts supply. It’s companies like these that we should all be supporting and spreading the good word of mouth.

    well done, my £200 Roberts is stuck with the orginal DAB and could not be upgraded to DAB+.
    Still works with some stations but not all. I suppose that’s the problem when you buy in to a new service with early hardware, they don’t know where it will go in the future. Plus it most likely more hardware than soft

    • @sdgelectronics
      @sdgelectronics  2 года назад

      I was unaware that there were incompatibilities with original DAB equipment. Pretty rubbish if that's the case!

    • @Monkeh616
      @Monkeh616 2 года назад +1

      ​@@sdgelectronics It's much the same as the move from DVB-T (Freeview) to DVB-T2 (Freeview HD). Stronger error correction, a codec invented some time after the 1980s (from MPEG-1/2 layer 2 to HE-AAC), and so on. Time marches on - we've had DAB+ capable hardware on the market for at least ten years after all.

    Hi there! I'm working on repairing an iStream3 where the power button doesn't work (same rotary encoder as you're working with, I'm pretty sure.) Volume works OK, though. I am located in the USA, so ordering the replacement encoder from Roberts will cost a pretty penny in shipping. Were you able to find a compatible part at all that is available from Mouser (or another supplier)?

  • @wayneaylmer572
    @wayneaylmer572 Год назад

    Could you please tell me which wire it is inside a Roberts RecordR is the one that represents the scan mute? Obviously on FM mode when you scan it mutes the white noise sound between stations while it's scanning, I need to know which wire or component it is that does this on the circuit board. If you could help that would be fantastic

  • @PapasDino
    @PapasDino 2 года назад

    Nice fix...but even though the encoder terminal solder connections appeared good did you simply reflow them to see if that resolved the issue? I'm sure it probably would not have but that would have been an even easier fix if that was in fact the issue.

  • @qviewq2071

    I used to repair Roberts radios for the Wireless for the Blind Fund. I learnt to hate them as they always had something wrong with the sound. A sort of hidden distortion that gave me a headache when listening to them for more than a few minutes. I am sure now they are a modern design that they will have fixed that problem. Are they still making them in the UK? The only manufacturer left I would guess. They used to be in south west London I thought but this set is labelled as Yorkshire. I like the vintage styling and hope it sounds better now..

  • @proudsnowtiger
    @proudsnowtiger Год назад

    Nice repair. If I was spending that much on a radio, though, I wouldn't expect a mechanical encoder. Roberts so often does stuff that's almost very good, but some corner is cut somewhere.

  • @Mrdibzahab
    @Mrdibzahab 2 года назад +2

    Those encoders frequently fail, is my experience, usually by sending seemingly random pulses. Turning slowly clockwise then sometimes becomes turning anti-clockwise at high speed (or the other way around). Depending on the application, this can make you deaf or it can zap your prototype :(.
    I never found a clear cause either when examining them.

    • @jaro6985
      @jaro6985 2 года назад

      The high speed is due to contact bounce. Encoder feel is highly dependent on the software routine that is processing it, if it was poorly done, as the encoder ages and gets dirty, response will get worse.
      Probably not the case here as there was no response.

    That 4.7k resistor value seems odd.......99.9% of the time it's 2 pairs of resistors and a couple of filter caps. Cant see why the A channel would be any different to the B channel.

    • @sdgelectronics

      My guess is shared function for the Verona 2 module, possibly JTAG or some other interface

  • @HwAoRrDk

    Huh, didn't know Roberts sold spare parts. Would have been useful when I wanted to repair an old radio a while back. The small custom-sized mains transformer had failed open-circuit. Instead I bodged in a DC barrel jack and run it off an old phone charger.

    • @sdgelectronics
      @sdgelectronics  2 года назад +1

      Neither did I, I just asked on the off chance if they had a part number for the encoder so I could find an exact replacement.

  • @BM-jy6cb
    @BM-jy6cb 2 года назад +1

    Pah! That's not a repair. You cheated by just ordering a new encoder instead of repairing it 🙂. Seriously though, nice job. It's very gratifying getting a bargain and saving a perfectly good item from landfill because of the throwaway society we live in. One of the perks of knowledge. I've fixed a few of these problems on bargain basement items just by disassembling the encoder and tweaking the fingers up a tad.
