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?

Vestel belsősElőször azt hittem tápegység gond, de probáltam másikkal azzal is semmi.Arra jutottam, hogy bontom tovább, A világitást 2db JL.D320B1235 számú ledcsík adja, kérdésem az lenne, hogy nem tudnátok megmondani milyen smd ledek vannak rajta, milyet lehetne rárakni a hibás led helyére,?Vagy valami más megoldás, led szalagból valamit összehozni?Most tartok ott ,hogy pattintgatom le a fényszóró vackokat, úgy gondoltam azt majd pillanatragasztóval visszarakom.
JVC LT-32A80ZU "padlóra került". A tápegysége adhatta fel? Nincsen jelzőfény LED sem. Ajándék!

Sziasztok!
Egy két nap járatás után jelentkezett a hiba, ami a csatolt képen szerepel.
Úgy tűnik hogy eltolva kirajzolnál újra a sorokat, illetve beremeg a kép.
Találkoztatok már ilyen vagy hasonló problémával?
Válaszaitokat előre is köszönöm! Üdv
