A common problem is poor solder connections on the transistors that drive the power relays. QX801 and QX802.

    i have found QX801 with a poor solder connection, resulting in it arcing..
    after i resoldered it in properly QX802 exploded.
    could i possibly have damaged anything else? or will replacing these 2 MOSFET transitors fix this problem?
