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.
A címben szinte minden, csak az nincs hogy már beleőszültem és tépem a hajam.
Már mindent cseréltem ami mozdítható, nem akarja az igazat.
Hátha valaki már izzadt hasonlóval, mert én kezdem feladni.
Üdv József.
Sziasztok!
A tévé, időnként elnémul és néma is marad ki-be kapcsolásig. Csatornaváltáskor leginkább.
Már több helyen olvastam a hibát de a megoldást még nem írták sehol. Volna valami jótanács?

Sziasztok!
A fenti gépnek zöld a képe, antenna nélkül lepróbálva. Katódok testre, kék semmi... JVC feliratos samsung cső, A68QFZ893X002
Próbáltam regenerálni, adtam neki 12V-ot, négyszer vagy ötször is végigmentem rajta, de a kék, mérésnél éppenhogy van (100mA), icipicivel mindig jobb, de csak 12V-on, 6V-nál semmi...
Sikerült már valamelyikőtöknek ilyen Slim szemetet rendberakni?
A héten jó lenne túlesnem a gépen, van elég más dolog a házzal kapcsolatban :)
Köszi!
Üdv:
Pityesz
