From the manual. You need to change some settings inside the unit to change it back, or buy a psx-r. I'll dig out the instructions later for you. They are somewhere on the forum too.

Flashing Red
The Cyrus IIIi is modified for
PSX-R but the PSX-R is not
properly connected
Check PSX-R is plugged into
Cyrus IIIi and that both units are
connected to the mains
Flashing Green
A PSX-R is connected to a Cyrus
IIIi which has not been modified to
take the PSX-R
Unplug PSX-R, check Cyrus IIIi. If
Cyrus IIIi works OK, return to
dealer for modification

ive taken the top off and changed to 2 fuses when i power on it does the light up stage
but soon as a button is pressed it blows them both
it worked for 5 minutes yesturday before it went
im not 100%sure but may be the speaker terminal might have touched both poles
this has been suggested to me as its very strange that it played then stopped?

Having the jumpers set for PSX-R should not cause any fuses to blow - it should just refuse to power up properly.

If you shorted the output with no music playing you would probably get away with it. If you short the output with music playing at any significant volume the chances are it will blow the output stage on that channel.

Unfortunately, few people like working on a III/3i because there will often be collateral damage to driver transistors and possibly other components.

No - they are still quite sought after because they were (I think) the last generation of Cyrus integrated amps that had a phono stage built-in, and they sound good - so repair is probably still an option worth looking into.

People tend not to like working on them because they were the first generation to widely use Surface Mount components - but that just means it takes more time and accuracy to do the work properly.

No, Cyrus will no longer work on a III or 3i. You would have to find an independent, like the one already suggested (who I have no experience of, I should add, for accuracy).

Just to be clear, I haven't used the guy I suggested earlier so I'm not making a recommendation but it must be worthwhile giving him a call & discussing the problem. He might offer a free diagnostic check...

TBH I don't think we've ever had any forum members who do work like that on a commercial basis. I occasionally work on Cyrus products, but only for myself - I don't have any form of liability insurance so I won't touch other people's stuff.

IMO it's a sad state of affairs, but manufacturers in general (Cyrus are no more guilty than most others) do not want third parties fixing their products outside warranty - they want us to just throw it away and buy something new, so (for example) they tightly control circuit diagrams and service manuals, and they won't sell parts outside their dealer/service network.

Having said that, the situation with the III is not quite so bad, because service data is generally available. Your best bet is probably to find a general repairer of electronics rather than trying to find a Cyrus specialist - I would guess you should expect to pay £120-150, but that will depend on what needs replacing.
