Hozták ezt a tv t hogy bekapcskor bepirosoodott a kép rámérve cseng a red katód a testre,illetve hát nem is tudom mire cseng mivel csenghet a fütőszálra is,hogy lehetne megtudni,vagy próbáljam egyszerüen lesütni öszezárva a fütés lábait,hátha sikerül?
Üdvözlet Mindenkinek.
Hozzám került a fent emlitett LCD-tv (kb 7-8 éves). A hibája az hogy bekapcsolás után öt percig fut a kép ezután megáll és a tv rendesen működik.
Úgy kb két (2) óra elteltével elkezd újra futni a kép úgy tunerról mint bemenetekről. A tápban a feszültségek csak század (V) eltérést mutatnak (12,08V és 23,39V) a standbyhez és az induláshoz képest. Kicseréltem a tápegységben a kindikat de nem változott semmi. Arra kérlek titeket segitsetek tanáccsal hol keressem a hibát. Nekem úgy tünik mitha nem kondi de valamelyik félvezető volna a hibás.
A tanácsokat élőre is köszönöm.
Hello friends,
my SONY TV shows some missing LEDs I think:
After dissabling and measuring: The first and the last two transistors show 1,6 Volts. The second one shows 0 Volts:
Any ideas?
