KERUSAKAN EW/gambar tidak lurus pada TV POLYTRON U-SLIM
TV POLYTRON U-SLIM dengan kerusakan EW/gambar tidak lurus,
1.Atur EW
lewat sermode
2.Jika tak mempan,buka cashing
cek/ganti capasitor
C813 333/630V
elco C814 aslinya 6.8uf/50V ,
3.TV start
- standbykan lagi
- masuk service mode dengan cara tekan menu remot sampai tv
nyala,tekan angka 1013
- adjust EW,dan ini adjust EW yg biasanya tepat:
1013 H-SHIFT 18
VCEN 10
V-AMPL 33
H-SIZE 33
EW-TRAPZ 47
