Üdv mindenkinek Sony KV 25FX30E tip tv hez keresek kapcsolási rajzot
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.
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.

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
