hello buddy: the hor seems to be overdue, ... maybe the pulse of synchronism from the hor salt may not be well received ... check the C450 of 680pf x 2000v and the C451 q, it is between mass and the C450 ... C451 reduces the amplitude of peak voltage q, leaves from the collector of the tsh ... also check the R467 of 10k ohm and see if it is not open ... measure the zener VD483 and see if it is not leaking or short. ..the pulse of synchronism arrives from this line to pin57 of lc n301 -... these data are taken from the PH08K-N22 chassis ... if there are no chassis coinsidencies you comment it ... greetings !!
