Your computer should recognize the Olympus as a USB disk drive. Use Windows Explorer to look for it, and see the files inside.

Ok so no guarantees this will work, but it did for me and I knows it's very late but hopefully it will help someone else with a similar problem.

I had the same problem and as clmrt5000 said a very long time ago there could be an issue with a ground loop, although this is likely to give a high pitched buzzing sound.

This can easily be fixed by adding a switch to disconnect the mains earth from the back plate, or you can just unscrew the earth and tape it up, this fixed my ground loop, (some models already have a ground lift switch)

As for the "boiling" sound I also got a saw tooth wave sound (like a strange squeak or beep that changed frequency) this is caused by faulty components, and thanks to Frank Johnson ( who suggested that you can simply and easily replace 3 capacitors on the main amplifier board (c58 - 47uF 63v or 100v) + (c52 & c53 - 220uF 25v) but stand them away from the board on the length of the capacitor leads to prevent them from absorbing heat from surrounding hot components (with heat shrink tubing to prevent shorting)

Now my sub works as good as new, apparently these 3 capacitors can cause all kinds of problems it's a common fault, so if you are handy with a soldering iron, or know someone who is you could save yourself a lot of money by repairing you faulty KEF sub.

p.s. if you have ANY of the KEF PSW subwoofers they all have similar issues, you can find a guide to fixing them at the link above, Frank is a brilliant and very helpful man.

I'm not sure if the other answers even come close to answering you questions.
Since you know nothing about it you might want to get a manual first off.
More info on your model here -

There are selection trouble shooting & help are located here -

Additional tips
All light bulbs
that are located in the key pad "light box" "First digit", "Second digit", Reset / Re-select etc.. are controlled and LIT BY THE SELECTION COMPUTER. They must have the correct bulbs installed! These are special 28V bulbs. Depending on your particular jukebox model, you NEED to use one of the two types listed below.

GE 656 - 28V .06A 2500HR LIFE T3 1/4IN WEDGE BASE MAN19600 EIKO BRAND or


Installing a 6 or 12 Volt bulb here will cause damage to either your replacement box, and / or the resistors that are located on the small circuit board on the back of the light box. (These resistors are inline on models using 1819 bulbs)

BOTH lamp types look exactly like 12v bulbs, BUT THEY ARE NOT, and are often mistaken for 12v bulbs. This is a very common mistake made by many Seeburg owners, so be careful with this.

The HDMI inputs are pass through inputs only. The reciever cannot recieve any sound signals through the HDMI's. The reciever acts as a selector switch for the HDMI inputs only. Whatever input you have selected on the reciever is the one that is being sent through the output to your TV. The "unlock" display shows when there is no sound signal sent to the reciever. There is no code to unlock. This is the reciever's way of telling you that there is no sound being sent to it from that input. Since there is no sound being processed from the HDMI's, you need to hook up an additional audio cable from the device to the reciever (preferrably an optical cable). When the reciever recieves an audio signal, it will then "unlock". I know it is confusing. I had to look into this problem myself, so I'm happy to help. Higher end recievers will actually recieve and process sound signals from the HDMI's. When I bought this one I thought it was going to do the same. That's what I got for trying to save a couple bucks on the cheeper model! Although it is still a good reciever.

Bad news the main power amp has failed.
The good news is that the service manual is online and it's free.
You will need to read the manual and find IC500, which it says is an RSN3502C.

Bad speaker connections, or poor wiring, causing a short circuit. However it could also be short in the main amp section. I think it's the protection system that is stopping it powering up.

PCM 2 is basically normal stereo sound. If you want to use Dolby settings it has to be set to bit-stream, or Dolby.
However that is in the amp settings. And if it is switching off before you can change it, then it's likely that the protection circuit is sensing an overload caused most likely by either bad speaker wiring, or a bad speaker, or faulty connections. For example two speakers connected to the same channel.

It would be normal practice to connect the Equaliser via the tape in and out of the amp, to the Equaliser in and out. If you are using a tape deck, then that goes into the Equaliser's sockets for tape decks.
I wouldn't use the Equaliser on any of the Dolby or other coded sound modes as it could effect the signal.

Some of these old tape machines used a switch that switches between playback and record. However dirt can get into the switch so it doesn't make contact anymore. Some Servisol switch cleaner will clear the problem, unless it has broke.
It could also be a bad connection on the tape head.
Also check the input you are recording from. For example will it record on the microphone jacks, but not the others. Maybe a faulty socket?
