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!
Ez a PT90-es alap hibával érkezett (a sorvégfokozatban a CD15 kondi egyik lába kiégett, ami ellőtte a sorvégtranyót, és zárlatos lett az STV9306 EW lába is - mind csere). Ez után a készülék üzemel, sortáp 145V stabil, viszont a geometria még hagy kívánnivalót maga után. A sorméreten és linearitáson egy picit állítani kellett a service-menüben, viszont hibajelenség továbbra is, hogy amíg a kép jobb oldala függőlegesen egyenes, addig a bal oldal "cakkos" és ez TXT-nél érzékelhető a legjobban.
Tapasztalt vagy javított ilyen hibát valaki?

ez a TV egyik héten kifogástalanul műkszik, de a másik héten nem lehet bekapcsolni mert felvillanás után azonnal standby-ba esik vissza. ilyenkor még véletlenül sem indul el. Aztán 1 hét múlva megint hibátlan.
Félre lett téve 1 éve mert így használhatatlan, ehhez kérnék segítséget !!!
A Nagyfesz Panelt tönkretettem addig addig kínoztam a kísérleteimmel, hogy elinduljon. Van ilyen valakinél bontott vagy új ?????

A Hibát nem találtam meg, egyik nap kifogástalanul indult, másik nap standby-ba küldte a tv-t felvillanás után.
SZEVASZTOK !!!
csak hobby szinten vagyok felkészülve, van egy forr pákám, meg egy voltmérőm.
KÖSZI !!!
