got a untested 720 board set from a fellow klov member. Tested the boards out, turns out the top board is good. The bottom board i didnt bother testing cause i noticed things broke on the board right off the bat. The resisitor for Hsync R17 was broken in half. Also the connector J13 i replaced cause all the pins were bent up..
Repaird those two things and tested the board.. Now switcher would not go on, and LED on board did not light.
So i started looking at the board again and found capacitor C7 was broke, one of the sides was pulled out of the capacitor. Repaired that with a 1uF 50V..
Now i get switcher power light and i get voltages to the board (5.0) LED is now lit.. BUT i get a BLUE screen... Can not coin up or play or anything...
Now the CRYSTAL 32V (at Y1)in the center of the board, one leg was hanging out of the baord. I re-soldered it back in there.. ( Do you think this is bad now?? Like should i replace it??
my other question is, anything else i should check on this board that commonly "goes" on these boards that you guys know off???
Heres a pic of what i replaced so far>:
