Just to follow about the K4003

The power supply of my amplifier is good. When I put nothing on the input the right channel has 0 V in output and the left channel has 17,6 V in output.
I have desoldered the TDA2616 and tested the output and the input pins.
Between pin 9 and 3 I measure 19,6 kilohms wich is good according the block diagram of the manufacturer, but between pin 1 and 3 I measure more than 20 Meghoms that is not right (the inside resistor is a 20 kilohms).
The TDA2616 has a default! So how can I do to change it with the warranty?
