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!
Egy két nap járatás után jelentkezett a hiba, ami a csatolt képen szerepel.
Úgy tűnik hogy eltolva kirajzolnál újra a sorokat, illetve beremeg a kép.
Találkoztatok már ilyen vagy hasonló problémával?
Válaszaitokat előre is köszönöm! Üdv

Kedves Kollégák!
Ehhez a Tescós csodához (JVC LT-40HG48,ch:17MB82S) keresek flashtartalmat.
VES400UNES-05-B kijelző van benne. Ha valakinek lenne, kérem szépen küldje el.
Előre is köszönöm.
Tisztelt kolléga urak!
Segítségre szorulnék a fentiekben említett tv miatt.
A jelensége hogy euroscart csatlakozóval megy a médiaboxról és az lenne a hibája hogy elmegy a kép,az euroscart mozgatására visszajön de de kisidö múltán ismét elmegy a kép.Én euroscart aljzatra gondoltam volna de mivel két aljzat van mendkettőnél ezt csinálja,sima koax bemenetén pedig a kép alja ugrál,de nem mindig az sem.Szerintem érintkezési hiba lehet csak nemtudom hol kezdjem el a keresést.Ha találkoztatok már ilyen jelenséggel megköszönném a segítségetek.Sajna elég kevés tvt javítottam még és kezdő vagyok benne.Köszi Mindenkinek.
Üdv:Tibi
