Sziasztok!
Nem indult, kaptam hozzá frissítőt, jó lett minden, a kép is szuper csak éppen fejjel lefelé.
Van valami megoldás?
Próbáltam kiolvasni a profilt de sehogy sem olvassa ki (DowloadProfile)

Sziasztok.
A címbeli tévé inverter trafójának szekunder tekercsein az alábbi értékeket mérem ohmban:egyik tekercse 980 ohm a másik pedig 1030 ohm. Ekkora különbség (50 ohm) már trafóhibára utal? Amúgy mennyire szoktak megegyezni ohmikusan a szekunder tekercsek? A trafó száma: TMS93264CT
Egyébként a tévé háttér világítása nem műkszik, csak egy másodpercre felvillan majd elalszik tehát inverter hibás. Kérdésem még, hogy esetleg egy rossz csőtől megy tönkre a trafó vagy pedig simán a nagyfesz húz át benne?
Köszi!
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

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?
