Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Systems DSP 5KC.2 Problem

Hi,

I Recently purchased a D5KC.2 from a fellow 'Hitchhiker' and we experienced an unusual situation.

The seller (whom I trust) supplied me with a video of the unit fully working prior to my purchase and less than 2 days later I've received said unit which powered up and displayed correctly ... but there was no sound (save a single click when powering on).

After trying all sorts of 'basic' things, typing and leads etc. still no sound … it recognised the input signal (on the display) and everything seemed OK but still no sound.

So, I dismantled the unit, injected tone into the power amps and proved they worked (the usual cooked resistor though).

I then delved into the DSP 'can' and located two sick looking capacitors (those indicated by red arrows)



I Pulled and replaced these two capacitors and surprise, surprise … sound is now produced!

My question is, what is the connection between these two capacitors (if any) and what else should I be wary of that could have caused this failure?

Basically, a heartfelt plea for a circuit diagram or at least a block diagram of the DK5C DSP board to assist my fix, any other comments would also be appreciated.

Paul.

Hi Paul,

Drop me a PM - happy to discuss.

Cheers,

Steve
