Yep, it’s definitely an issue with the top board. Let’s just hope it’s the capacitors, worst case scenario, it could be some loose pins on the Sony custom ICs or failing RAM on the top board.

Hi friedns, I just did I have been told and the is there are no changes :c , I only need to weld the C16 sector, but it is complicated, because from what I see it has no welding and that part is like burned. Any recommendations? Because only that sector I need to put a capacitor. Now if this is not the problem, I would like if you can tell me what part of the pcb it can be, I have a mini heat station, so I could take out the component and weld again. Thank you

thats not burned, it just needs cleaning.
that whole corner dont look good though.
i would replace the 2 ceramics and clean and resolder the ram too.

I will leave some photos of some C and can tell me I can replace it, as they look very little I would like to know some equivalence with which I can replace

C18

C3,C62,C61 and C59

And a question, the section ram is it? (IC22,IC23,IC24 and IC25)

I would really appreciate your help

the cans can be replaced by tantalum caps,
the ceramic ones are probably o.k. if you reflow the solder on the ends
the ram - just look at the pins on them - you will see what looks wrong
