Üdv mindenkinek Sony KV 25FX30E tip tv hez keresek kapcsolási rajzot
Sony FE1A sasszi KÉPHIBA
Üdv mindenkinek. A tárgyban említett gépet hozták be reggel képhibával. Bekapcsoláskor nincs kép és hang, de ha a képcső nyakán lévő pcf modulon a 9v lezárlatolom 1másodpercre akkor van kép is meg hang is. AKB-t is villog. Meg a zöld is kevés benne. 2 hónapja találkoztam ilyennel de azt se sikerült megjavítani. CXA2060BS rgb ic csere után helyzet ugyan az. Az RGB végfok tranyók cserélve illetve a vele kapcsolatos félvezetők is. EEPROM vagy milyen hiba lehet ez? Az EEPROM SMD! Akinek volna valamilyen ötlete kérem ossza meg velem. Előre is köszi.
Sony KDL-37EX402 the TV in dead, no LED, motherboard problem.
Hello

The TV does not show any sign of life , I started the troubleshoot as this , no power Led, no reaction when pressing the power button.

I checked the Power coming out from the power supply, the 3.3V_standby is correct and steady, then I checked the 1.2V_standby produced by IC6001 which Is good as well.

So I decided to control the main IC , IC4000 , he does not output any oscillation on the Xtal, Then I am now bloacked there.

The schematic is downloadable on this  website , the schema is weird because the processor is not represented with any Xtal output, but obviously it has one.

Thanks you for your hint and help.
SONY KV-S26A10e hotel mód feloldása
Sziasztok! Ez a tv úgytűnik, hogy hotelzárban van, mert a hangerő csak 70-ig megy és a menü nem érhető el sem a távról sem a gépről. Ehhez kérnék segítséget. Köszi. : Laci
