Hi i have a Nait 5 amplifer and today when i switched it on the Cd light started flashing . Then when i switched input to tuner it starting flashing again . Anyone had this issue or know the fix ? Many Thanks .

A flashing source button usually indicates either a mis-assigned input (not so much an issue with the original NAIT 5) or else a fault condition - e.g. over-temperature or over-current. If the latter I would check to ensure there are no shorts anywhere with the speaker cabling or socketry.

Otherwise, do you have all the link plugs fitted (5pin DIN round link and the double headed ribbon link)? Could the ribbon link be damaged in some way?

Otherwise, @NeilS may have more ideas here.

Hi thanks for the advice . I will check cabling into the amplifer . I have naim connectors for speakers and Din connectors to cd player and tuner . I dont think it is an overheating problem as it started flashing from cd player to tuner when first switched on ?

Is there a reset you can do on the remote i read somewhere ?

Kind regards Nick

Was it fine before today? Anything changed with the system since last used without issue?

Are you sure it’s a Nait5 & not a Nait5i or Nait5si? How many inputs does it have?

That’s a Nait5i or si. The original Nait5 had six inputs, a mute & a tape monitor button.
Sounds like the protection opto-coupler has gone faulty :-1:

Neil.

You should speak to your Naim dealer who can get a repair quote and arrange repair for you.
