No video/audio MacBook 13'' , broken logic board?

I've working in this MBP after someone split red wine on it. After cleaning and replacing the original keyboard it wont show video or sound, i could hear the HardDrive working, also shown the light.

I toke all the memories out hoping it was a issue with it , when i turn it on there is no beeps or sound. I clean again the whole logic board, replace the thermal compound , test again and nothing happened But the status light stays lit up.

Any suggestions?

I will appreciatie any help possible suggestion to fix this issue.

You say "no beeps or sound" are you seeing the desktop? Is it functioning except for sound? IF SO it could be the audio board... if not you have a damaged logic board... spilled wine will do that.


Thanks for answering. My case as many others that probably i had read about is that i am allow to turn it on also can see the light status on , hear the Hard disk spinning but there is no image , any type of sound even when i try the memory test. So my question is do i need replace the logic board? or there is a possible non expensive fix ? Thanks for helping to solve this problem for all the community

Hook it up to an external display to see if the GPU is generating a video signal. If not, you will most likely have to replace the logic board.
