JVC HV32D25 HELP!!!
Üdv. mindenkinek. JVC HV32D25-ös tv felhasználó vagyok. Fárasztó, de évente kifekszik átlag 1x. Ha ez a fenti kifáradás elkezdödik, azt nagyon változatos színekkel produkálja, persze nem a tv kép színeiröl beszélek (írok), mert az nincs. A leggyakoribb az igen eröteljesen vibráló, homogén ZÖLD szín a képernyön. Teletext üzemmód után változik az ábra, akkor már nem "stroboszkópozik". Néha, egy 220-ból ki-be az segít, de csak néha. Van a lakhelyemen olyan szervízember, aki szokott segíteni rajtam. De a fentieket "örökre" megszüntetni nem lehetne? Telibe kaptam az olimpiát ezzel az állapottal. Ha van köztetek, aki ilyennel találkozott, és az én szintemre tudna redukálni valami okosságot, az nagyon jó lenne. Köszönettel. (chicho)

JVC AV-21FMG4G Chassis SCW-1362A blinks continuously after three failing power on attempts
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?
