WATSON | FA-3201-TS ch 11AK19P5 | Imagem espandiu e passado algum tempo encolheu horizontalmente | R629 2R7, C621 1M, FET 9NQ20T | ||
FIRSTLINE | 11AK19P5 | Sem abertura H. e tb transistor E/W queimado | Subst. C617 (680nF/250V) mais os comp. do E/W | ||
Bush | WS6673 11AK19P5 | Dead - D823 blown (not shown on cct) | When replaced still faulty, IC802 MC44604P chopper chip u/s - also check FET chopper Tr | ||
Bush | WS6673 11AK19P5 | Dead - check for dry joints | Also replaced LOPTr which then produced 1" line scan - D622 BY228 leaky & R629 2R7 o/c. There's a mod for psu (11DYC19P) to fit heatsink for diode that burns up | ||
