Reverts to st/by at sw on with 6 flashes from led | Over-current protection circuit (q600, 602) is operating, usuallyprobs in lop. to identify the cause, first dis fop chip (ic501). if set switches on with frame collapse, replace ic501. if set fails to switch on, dis ht feed to loptx. this should give 4 flashes of st/by led (no horizontal fly-back) showing that problem is in lop. check lop comps before condemning loptx. if st/by led continues to flash 6 times even with loptx disd, check r620 (270k) & r622 (470k) in over-current protection cct. | ||
