| SONY |
FE1
|
Reverts to st/by at sw on with 2 or 4 flashes from led | 2 flashes indicates an over-current error in line stage, & 4 indicates a frame fault. however, quite often, when 4 flashes occur it can still in fact be an over-current error as well as a frame fault. to prove which is the correct fault, measure pin 52 of the micro (ic001) at switch-on, and if this voltage goes high (anything above 0.6v) then it is in fact over-current. if it stays at 0v then the fault is more than likely within frame stage. | ||
