Ez a plazma kb öt óra után a fényképen látható módon becsíkozódik. Kontaktra nem reagál. Valami ötletetek?
További járatás után a vizszintes csíkok sűrübbek lesznek.
Láthatóvá tettem a képet.
Láthatóvá tettem a képet.Sziasztok!
Kérdezném a nagyérdeműt eme gép javíthatóságáról.
Anno csövet cseréltem benne, majd a másik csövet eladtam, most belekerült egy 50Hz-es tekercsel ellátott W76ERF, amire nincs tekercsem, mert az eredti eltört.
ESF-é volna esetleg. Csíkozás még megmaradt, RGB rész szerintem jó. Digibox behalhatott az esetleges előző cső csattogások miatt?
Előszedtem a gépet, mert a sorkimenő kellene valakinek.
Én úgy gondolom jobban járok így vele, de azért érdekel a tapasztaltak véleménye eme TV-ről :)
Köszi!
Üdv:

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?

Sziasztok!
Nem indult, kaptam hozzá frissítőt, jó lett minden, a kép is szuper csak éppen fejjel lefelé.
Van valami megoldás?
Próbáltam kiolvasni a profilt de sehogy sem olvassa ki (DowloadProfile)
