Sziasztok
A fenti tv a mellékletben csatolt képet produkálja. Mivel elég méretes feleslegesen nem hoznám el. Okozhatja ezt a hibát t-con vagy kijelzőhiba lesz?
Köszi

Jó napot mindenkinek!
Olyan problémám lenne a fent említett tv-vel, hogy nincs rajta hang hiába állítom a hangerőt! Az aki javította előttem cserélte a végfokot, és egy napig volt rajta hang, azóta nincs! cseréltem a végfokot én is (TDA2615) Előtte ellenőriztem a tápfeszültséget hangszórókat, és minden rendben van! Esetleg valakinek valami infója, hogy mi lehet a probléma?? Talán eeprom?
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.

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?
