|Yamaha Tyros2 Workstation||Even after replacing the SubCPU, a 208 pin surface mounted component, the synth remained silent,|
and the activity around the SubCPU did not look like normal data communication.
The remaining suspected components are hard/impossible to get hold of, and/or impossible to replace.
A pity, since the rest of the Tyros works well: the display and computer part, the keyboard, and all buttons and lights.
MIDI does also not work, so this synth can only be sold in parts. Take contact if you need Tyros2 parts,
for instance the sound module DAC2A, which probably works.
