Starting problem Dead TV. RCA 32F530T, chassis ATC113CD4, year 2004. I Replace flyback # 257807 along with the H-O/P XSTR (2SC5148 original Toshiba).
one or two places on the screen depending on the white level (contrast), always moving in half screen area on the top. Same symptom with video and RF input. If i lower the vertical height, tearing lines disappear. No error code in service mode.
RCA flyback, NLA) , 257807, 257805 and ACME-2632 (replacement for RCA #261163). Still have exactly the same problem with 2 tv set. I checked parts in the horizontal and vertical circuit, DC supply, everything looks good. Ear low noisy flyback. See pictures I do a lot of research on the web and nobody has experienced this problem. Any suggestion? Bulletin note? Jungle ic? Damper diode failure? Flyback incompatible??? Someone saw that before? Thanks Pierre
