Hi!
Please help me to solve problem or guide me who can help.
My friend gave me Yamaha YSP-1000 in non-working condition (no power) and without remote controller.
I restored power by changing capacitor on Power board and now it turn on, but there is no sound on all inputs.
And on device screen "volume level" is blinking.
When I press "Volume up" button on device, volume level is growing, but still blinking.
So I decided to disassemble device to the DSP PCB and found out, that there is no cable, connecting DSP1 and DSP2 (cb4 and cb1 connectors).
In service manual for Yamaha YSP-1000 I found out that there must be connection between DSP1 and DSP2 via cb4 and cb1 connectors.
There is photo and service manual in attachment.
Can You tell me, is this cable must be connected to cb4 and cb1 or it is not necessary?
If the cable must be, how pins cb4 cb1 must be connected:
EMU1->TMS, EMU0->TRST, DGND->TDI, ets.
or
EMU1->EMU1, EMU0->EMU0, DGND->DGND, ets
