Sony
BE4A Chassis
Frame collapse. Replaced frame output chip, but picture geometry was not OK. The voltage at pin 8 of MC44007P chip measured low.
If picture Geometry after replacing Vertical outp. Chip is not in order, replace also MC44007P. (Replaced also STR-S5706 in case an overvoltage caused the fault)
