Sanyo VHR-D4710G VCR no sound.

Hi again guys.
Today I have a problem with this Sanyo VCR.
I bought it online, It worked sometimes.
I recap the Power supply and it started working fine.
Image is perfect and all digital effects too.
All of a sudden it stopped outputting sound. I checked for dried solders an all boards and soldered when needed, no fix.
I have no sound on playback, on tuner, or aux in.
On symptom I noticed is when it was working fine, the HI-FI led was on when I power up the VCR, now is OFF, A-B leds are on but when I put a tape they go off.
On one of the sound processing boards (has two) there´s a relay, I remember that when it was fine, when I power the vcr on, I hear the relay switching but now it doesn´t.
I´m struggling to find what is causing the problem. If it´s an IC, I think It´s garbade dispite the image still great.
I bought the service manual, wich I attach in my post.
I hope once again someone can help me fixing this VCR.

Hi Kasfamily.
Thank You for your answer.
Yes it has but I don´t have remote. I bought one online too, but still waiting for it.
Forgot to mention that the vu meters before were working too, but now they don´t too.
