Sony KV21LT1K kikapcsol FE-2 / Megoldva! /
Sziasztok! Ilyen hibám még nem volt! A TV bekapcs, amint a kép megjön, a TV kikapcsol, de csak akkor, ha antenna van bele dugva, és csatornán van. Kettőt villog. Ha nincs antenna, akkor megjön az OSD, mutatja, melyik csatornán van, és addig megy, míg az antennát beledugom, megjön a fény, és rögtön kikapcsol. Úgy veszem észre, hogy a képernyő kivilágosodásakor kapcsol ki. Ha leveszem a G2-t, akkor megy addig, míg ráadok annyit, hogy megjöjjön a fény, és rögtön kikapcsol! Mi okozhatja ezt? Köszönöm. Üdv: formasu
Sony KDL-40EX1 , no sound and no picture, power and backlite is there
Dear forum members, Perhaps anybody can help me with the Sony KDL-40EX1 TV set. I have this set here for repair , but I have no experience with this type of TV. It has a media box and sents the TV information wireless tot the TV. My problem is on the tv: no picture and no sound , the backlite works because I see white light behind the screen. There is also wireless communication because I can turn the TV on and off with the switch on the media box and on the TV itself. I have the service manual but this doesn't really help me any. So the power board seems to be working because I have high voltage for the ccf tubes and 12V for the rest of the TV. It is my idea that perhaps the main board is defective because I have no picture and no sound but I am not sure. Is there anybody here on this forum that can help me with some idea's. Thanks Fred Dijksman

SONY KDL-40EX721 Chassis: AZ2F Nem ad képet.
Kedves kollégák!

A készülék bekapcsolása után a hang és háttér világítás működik. A T-con panelen a tápok úgy tűnik rendben megvannak. A mainbord után a t-con bemenetén szkóppal mérve az LVDS vonalakon,aktív jelcsomag mérhető. A kijelző panelen,zárlat nincs a tápok megérkeznek. Az oldalsó coff chip-en a:
VCOM,VCC,VGL,VGHC vonalakon a táp elvileg rendben van. A vonalak ellenálása: 10és 40ohm. Jó lenne egy garantált flash tartalom,természetesen  a t-con panelhez is. Illetve személyes véleményetek. Lehet,hogy kellen a t-con-ak egy reflow? Kinek mi a tapasztalata .
Egyébként a kijelző tipusa: T400HW04 V.1
üdv.
