First clean it wery good. Then check converter voltages on 65Z 5volt to 3volt and 65e 3volt to 1.5volt. If volt exists try changing crystal 24.576 or 24.000. Choose correct crystal if your mp have one of them. if it is not working, connect your mp to computer holding short the memory chip. Is there anything connect to your computer? If not, check the USB jack and USB Cable. Finally if your mp not connect to computer, THE CHIP ATJxxxx was broken! ALSO there are double converter looks like led regulator.
