Help with super nintendo sound problems and crashes

[jam007]

I was playing and suddenly it was light, flashing time coming, and again will be.
restarts when the game has a sound as corrupt (like when you hear a badly tuned radio, and audio metal leaves) and in some crashes.
I am suspecting that some condenser (capacitor) is damaged but not seen with the naked
view if they are not blown and when should register on the multimeter to see if they are ok, plus you do not know what is the audio section (is one of those plates that have the audio chip attached to the plate and not as heavy to snes had the separate audio chip).


I test these games
- Batman returns, it works ok, but lost sounds
- The super mario wolrd, is played but the sound is heard horrible.
- The punchout Start crashes when I play (when I start playing)
the doom is played but nothing is heard (at the beginning of the intro but it sounds good and sometimes horrible crashes)
Here is the photo (sorry about the picture if they look a little blurry as I did with the cellphone camera) Super Nintendo SNES Motherboard SNS-001 Type 2 .

I have another plate that does not work snes video or audio, but if turned on, the use as a donor of the power plug, socket and fuse, if I knew how to get the capacitors surface that has me also dare to swap them if I knew which audio integrated circuit dare me to exchange it (on Google to get them out but as it is and is not nothing I can do.)


PS: already for another console, if you want to play I'll have to put a surge protector, which unfortunately are the electric companies and to top snes fuse did nothing.

PD2: I did the test with RF cable and it works fine in another snes I own, so that's not the problem

Thanks in advance
