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.
Sziasztok
A címben szerepló tv javításában kérnék segítséget.
A tv nem kapcsol be csak a standby led villog 19et vagy 20at majd kezdi előről.
Sajnos rajzot nem találtam hozzá rajzot. main 17MB61-2
Púpos kondit nem találtam. Sajnos nincs fesz érték a csatik mellé írva így rajz nélkül nehezen boldogulok.
Valakinek tapasztalata, ezzel a tv vel kapcsolatban.
Köszönöm a segítségeteket.
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!
Ezt a készüléket Angliából hozták be, de se BG, se DK hangnormán nincsen hangja csak sistereg. Próbáltam volna bejutni a szervízmenübe de nem sikerült 4725 kodokkal, vagy nem is itt lesz a gond? Segítségeteket előre is köszi.
