440SI STUDIOWORKS
|
Sudden horizontal oscillations on the screen. Sometimes it almost completely loses its shine, then it suddenly becomes good. shatters the sides of the monitor. | Pin 02 of the fly back is +b, and must be fixed at 65 vdc. if it is varying, it could be the d701 or q704. The most likely is the 10k/1kv ceramic capacitor, it is right in front of the fly back 6174z-1003d. Note: in this defect, the technician usually changes the s,h. and the fly-back..., but without success. They are not the villains. Good luck my comrades. carlos |
