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!
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 :-)

I copied the spi flash and nand from a working board of the same model, but it still won't turn on and the standby LED flashes 13 times. Before reprogramming, the LED also flashed and the TV wouldn't turn on. It also wasn't possible to upload software via USB. I read this via UART:
