Default Sony TA-F55 won't come alive

Hello Everyone
I got my hands on a Sony TA F55 amp, and it's not turning on...
I posted a while ago about it just swapped the letters, so maybe this is the reason why i didn't really got replies...
Anyway, the story is the following: I got the amp, it didn't really do anything, after some soldering I managed to turn it on, it produced some really bad signal, but i could actually hear the music...
And now it's dead again. I have the output voltage from the power supply, and there's relay, called RY401, which controls the power for the entire system, and it won't come on... In the worst case i have to desolder the components one by one, and test them, but I really dont have that much time. So if any of you can help me with that, it would be really appreciated. I have the schematics for it, if it helps...(I know i'm quite close, cause i've seen it working, so I really wanna make it work).
Thank you
