Sziasztok.
A fenti tv-vel közdöttem.
Minden rendben van vele elvileg ha a menü gombot megnyomom a távon rendesen bejön a menü.
Ha itt lépni akarok bármerre kilép a menüből vissza a tv-hez.
Így nem tudok gyári beállítást se csinálni meg igazából semmit.
Epromra gyanakodtam, kivettem tettem bele üreset, így el se indult.
Tartalmat nem találok hozzá.
Szervíz manuál szerint FT3 sasszi.
Esetleg volt már ilyen hiba valakinél?
Merre tovább?
Köszönöm előre is.
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?

Tisztelt Kollégák!
A gondom ezzel a 100Hz-es döggel, sötét képernyő hang van.
G2 tekerve szüke visszafutásos háttér.
Videovég cserélve, a digi-modul rgb lábain 0,3V van.
Saját eeprom mentésemmel a helyzet ua.
Ötlet esetleg rajz jól jönne.
Köszi, üdv, kovácsa
Sziasztok!
Ezen a készüléken semmi képtartalom nincs, csak csíkok vízszintes/függőleges irányban. T-con táp (rt6923) forr, ha lekötöm a kijelzőt akkor viszont nem. Létezik, hogy zárlatos a kijelző??? Nekem még ilyet egy sem produkált, tapasztaltabbak véleményére lennek kíváncsi.
Köszönettel: Kiss Z.
