Default Troubleshooting Sony STR-DE975

I have a Sony STR-DE975 that a friend gave me and it's broken. If I turn it ON ''protector'' is written on screen. I open the case and saw that a resistor was cracked open and pcb was burnt. I was reading the service manual and I remark that it was a 1KOhm 5% resistor so I change it for a new one and repair the burnt pcb trace with wire. I put the receiver ON and smoke was coming out of the resistor so I shut it down. Now I'm not sure of what is not working correctly. I have a multimeter but I don't know what to test so it would be pleased if someone could help.

Here are some pictures:
