820-2375-Ano picture only beeping

Hello;

I got a macbook air today with the next problem.
when powering it it beeps continiously, and no chime is coming and no picture is showing

where should I start measuring?

thanks.
 
I need to know more about what the problem is concerning the MCP79U. Is the chip totally dead or a reball can repair the problem? If the Chip totally dead can changing the chip help the problem?
Boards for such macbook are still costy and the customer cannot afford spending 300,-$ for a refubished board.

You can't. Just take from me that it is. Reball, reflow, replace do whatever you want but this thing is not worth time and effort. Do NOT repair these pieces of shit!
