Hello
Six blinks of standby light in Sony TVs denotes the absence of horizontal oscillation.
No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206.
In most cases the Ic is foud defective. anyway check its soldering points for any loose contact, or bad solerings. Check the line drive transformer, a very little transformer soldered directly to the main printed circuit board, very close to the horizontal output transistor. Check its primary winidngs for open. If it gets open no horizontal drive signal will be present at the base of the horizontal output transitor, that also may the cause of horizontal stop.
