Default Rockford Fosgate type RF X2

Working on a RF type X2 with DSP board. Sometimes the amp won't "unmute", but all voltages are there, display is ok, but cannot activate any button at the dsp keyboard. When pulsing the remote (about 10x...?) the amp is working ok.

It is like an other thread i think: Rockford Type RF X2 was there any solution provided for that problem?

I see at the SG3525 a sync-in signal coming form the DSP board. Only a diagram available for the amplifier /power supply part, not the dsp board...

Maybe some leaky smd capacitors on the DSP board..?

After replacing all the 10uF/25v el. capacitors (smd) on the dsp board the amp was working 100% again.
