KDL-26U2000, 32U2000, 40U2000...
TV Shuts off after "some time", LED blinking 4 times ( Panel Error ).
This is caused by SMD Fuse F003 on the Inverter ( 0,3A or 0.5A according to size of TV ) going Ohms instead of conducting perfectly.
Change this to a new one.
Fuse is located just beside the power cable from the PSU...
Fault off course relates to all models with the same inverter board ( KLS400W2 )
Sincerely, Lars / Sound2Vision
Az angolul nem tudóknak:
KDL-26U2000, 32U2000, 40U2000 ...
TV kikapcsolása "után egy ideig", LED villog 4-szer (Panel hiba).
Ezt az okozza, hogy az inverter SMD biztosíték F003 megnyúlik (Ohm értéke lesz 0 helyett) (0,3 A vagy 0,5 a TV méret szerint) .
Új alkatrész cseréjével megjavul.
A biztosíték a tápegység hálózati kábele mellett van ...
Hiba természetesen vonatkozik minden modellre, ami ugyanazzal a inverter lappal készült (KLS400W2)
Tisztelettel, Lars / Sound2Vision

Sziasztok!
Adott anyós KV-29LS60K csodája. A baja az, hogy bekapcsoláskor a gép elindul, van rendes képe, majd 1 perc alatt teljesen besötétedik, gyakorlatilag semmi nem látható rajta. Nem kontakt hiba, ütésre, melegítésre, hűtésre nem reagál. Néha gondol egyet, kikapcs, 2-es hibakóddal. Az érdekesség, hogy ha kikapacsolom, majd újra be, akkor normális a kép, majd 1 perc, ismét szépen lezár a képcső, és sötét a kép.
Nyúzás után a gép bekapcs után ad normális képet, majd tökig kinyit, vibrál, kikapcsol. Néha 2, néha 3 villogás a LED-en.
merre induljak?
Sziasztok!
A fenti TV-n bejön a SONY logo, majd üres kép és kb. fél perc után újraindul.
Letöltöttem egy 4.027_EUA.bin firmware file-t, de a TV nem olvassa be. Memória egy BGA One Nand flash, amit még nem próbáltam írni, és tartalmam sincs hozzá.
Van valami ötletetek?
