We take Voluson P8 as example .
When it is unable to generate image ,firstly we need to check ultrasound probes one by one
If all of the probes are in good condation and imaging disappeared .,then the fault may locates in the Channel board
DBM64S Assy PN:5573639-2 Channel board for Voluson P8 definitely is the one we need to inspect
the below photo shows the Chip which process image on the circuit board .
