Sziasztok!
A cimbeli lcd tévén koaxról tökéletes a kép, de nincs hang, scartról fekete-fehér és ugrál a kép de van hang. Mi okozhatja ezt a hibát? Mindkét scart csatiról ugyanolyan rossz a kép.
Ha van róla rajzotok légyszi küldjétek át. Köszi.
Sziasztok!
Uraim bevállaltam a jelzett gépet aminek függö eltérítés és talán EW hibája van ( a kép a tetején 15cm-re nyomott és a kép két szélén párna torzítás van.) Cseréltem az elkokat a függővégfokban a D402 de semmi változás kivettem az L461 tekercset de semmi viszont ez azt eredményezte hogy párperces üzem után tönkre ment a D522 kettős dióda egyik ága ( a hűtőborda forró volt). A dióda típusa FMV-3FU ezt nem látom senkinél vajon mivel tudom helyettesíteni? Egyáltalán mi lehet az alapprobléma oka?
Nagyon kéne a segítség! Várom a véleményeket. Sziasztok.
üdv: Lajos
Üdv Mesterek!

JVC AV-21FMG4G Chassis SCW-1362A CRT TV blinks continuously after three failing power on attempts.
According to the customer, the upper portion of the screen started shrinking with horizontal lines, then ended with a single thin horizontal line.
This suspects the vertical drive section to be problematic. No vertical output though vertical in put is OK. After conducting an ESR check for capacitors in the vertical section, C428 (100uF 35V), connecting VCC1 with Pump-up pin # 3 of the IC, it measured 1200pF. It was replaced but still no vertical output. So changed the vertical IC401 (TDA78040), and the output appeared, but still blinks after three failing start-ups. I, m suspecting the corrupt EEPROM data.
CPU: TDA11010H / N1D00
EEPROM: 24C16A
Any one with EEPROM dump for this model or any help please?
