TOSHIBA	TV 2159NFS U-18	Inoperative, when I opened it I went to take tension measurements I heard a tic arming and disarming I released the vehicle it oscillated but no filament could be seen. It was broken, I soldered it and the defect continued, according to the customer's information he said the corners were rounded, I went straight to the horizontal part and released the Q 432 and the TV worked normally, then I put the 432 transistor back in and it didn't work.	Q-432 I released it and it was normal, I didn't need to put another one in its place.		wagner
