Hi

Here is the problem
PS2 V9 with Matrix Infinity chip.
PS2 worked fine for 2 days.
Afther 2 days ps2 works fine but no sound is coming out.

Afther some messurement i discovered the following.

Near the A/V outlet is a chip located called cs4335k this is a stereo D/A converter for datasheet see (http://www.alldatasheet.co.kr/datash.../datasheet.pdf)

These are the messurements

Pin 1 Digital audio at 1.24 volt PP
Pin 2 A block signal 1.7 volt
Pin 3 A block signal 1.7 volt
Pin 4 a sinus signal 1.65 volt pp (*)
Pin 5 no signal (this has to be analog out left)
Pin 6 Ground
Pin 7 5 volt powwer supply
Pin 8 no signal (yhis has to be analog out right)

I suspect the signal on pin 4 I compaired it with a other PS2 there it was 2.7 Volt PP But I can't fint where this signal is coming from can somebody help me with this.

Kind regards Albert
