Üdvözlet Mindenkinek!
Fent jelzett készülék raszterének jobb oldalán kb.15 cm.-es függőleges sávban kismértékben hullámos a kép, ahogy a mellékelt képek mutatják.Szervíz módban nem lehet korrigálni.A nagyfesz.kábel át volt égve, csattogott a képcső oldalához, a tulajdonos szerint akkor jött elő a jelenség.A kábelt "befoltoztam", a hullámosság eltüntetésében kérném a segítségeteket.

Sziasztok!
Jó kis occo tuskós tv. Még a JVC is elhatárolódik tőle. Tápok jók a main-on (T.MT5310.91A 12016)is. A szokásos firmware hibára gondolok amit bele is írnék az MX25L6506E flash-be.Viszont nincs mit bele írjak. Valakinél van-e működő ilyen tv amiből ki lehetne menteni a firmware-t? Előre is köszi.
Sziasztok!
Gyakorló szakiktól kérdezem: a fenti TV-nek másfél-két óra használat után elmegy a hangja. Kikapcs/bekapcs és minden OK. Egy darabig. Egy esetét úgy 3-4 kikapcsolással meg lehet úszni. Típus hiba lehet vagy sem? Ezen információ birtokában döntöm el, hogy mikor fogom szétszedni :-)

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?
