Why has the sound suddenly stopped?

Block Image

Hello, I wonder if you have any ideas? Whilst playing my digital radio on full volume, the sound suddenly stopped. Everything else still works: all lights, LCD display, channel selection, tuning, just absolutely no sound. When it happened, the sound was slightly distorted and then just disappeared instantly and has stayed away. The radio is meant to be of reasonable quality and is only about 18 months old. Any pointers would be greatly received. I am however, a complete novice, but happy to start learning and experimenting. If I make things worse then so be it. At least I will have given it a go. Many thanks :)

Bonkers - My revival Bluetune stopped producing sound. Literally ONE STAB of a headphone jack into the headphone socket on the top and it came back to life - BONZA!!!!

Does the headphone socket still work? (plug in a known good pair of headphones and try)

If the answer is yes, try plugging in and unplugging the headphones briskly, a few times.

The speaker might start working again.

The explanation: when you plug in a pair of headphones, the speakers will be muted by a switch contact on the headphone socket. Sometimes, especially when you don't normally use the headphone socket, this switch will corrode slightly just because it doesn't get any exercise, and the speakers will be muted even when no headphones are connected.

On the other hand, if the headphone socket doesn't work either, it is possible that the audio output amp has failed. You might be able to get this repaired under warranty, depending on where you're located - in Europe for example, electronic gadgets have a mandatory 2 year warranty.

Good tip, but no sound to headphones either nor to speakers after plugging headphones on and out of socket about 20 times. Seems like it might be the amp then. Any ideas how I would test that myself and what I may have to do to fix it if it is the amp? Many thanks.

Regrettably, my trusty search engine can't find any schematics or service docs for your radio, so I do not have the info to walk you a troubleshooting procedure. What you'd want to do, is figure out which of the components is the amp, see whether it's alive or not, and replace it if it indeed turns out to be dead.

However, you're most likely going to need:

* Some troubleshooting skills

* Suitable tools and at the very least a decent multimeter and better still, a 'scope

* A SMD-capable soldering iron and the skill to use it.

This is not really novice territory, and you might want to try your hand on some simple repairs first.

Thanks very much for all the time you have invested. I better admit defeat :)

Just remember that your radio might still be in warranty, so you might have it fixed at no charge.

It's not as instructive as tinkering, but still, it might be a solution.

I have my Robert Stream 63i lost its sound as well. Re-setting did not work, plugging /unplugging headphones either.

Everything works (I could hear it through the speakerphones), just no sound through the speakers themselves. It is such a shame as the Roberts system just came off the warranty. Quite disappointed really.

What is the life expectancy of Roberts dab radio? I have ecologic3.

I had a non dab radio for over 10 years and it kept working well.

The dab Roberts is ill after 3 years of service. No sound though the headphones work. Very disappointed.
