Sziasztok,
A fent nevezett LCD tv nem indul se távról se tasztról.
Amire jutottam.
Stand-by 5V meg van a main is megkapja ahogy néze a többi fesz akkor fog felállni ha az ON parancs megérkezik a mainről.Nem szűretlen. Viszon ezt az On jelet nem adja ki.
Ahogy látomaz SDA555M ic-ből jönne de ebben nem vagyok annyira biztos.
Ennek az ic nek a quarcz-a rezeg mértem szkóppal.
PFC-n 325V megvan.
Ha valaki találkozott már hasonlóval vagy van ötlete megköszönném.

Sziasztok!
Ez volt egy cetlin benne, típus hiján: AK41-JVC-496
100Hz-es 70 centis, SMD proci: SDA5550M A14
Sorki: 13020042A
Keresztanyumék hozták, hogy lessek már rá vagy dobjam ki :S
Bekapcs után után pittyeg, kikapcskor nagyon lassan egyre lasabban elhallgat.
Szétszed, mér és a következőket tapasztal :)
2SC5302 csontzárlat mindenfelé, STV9379FA szétrobbanva :S
Mire készüljek?
Köszönöm!
Üdv:

Sziasztok!A fenti tv eredeti hibája az volt hogy csak készenlét volt.Kaptam egy másik flash tartalmat amit beleírtam a memóba és így beindult de fordított a képe.Szervizmenübe belépve át lehet -e állítania a képet esetleg?Volna valakinek egy service manuálja a tv-ről?Vagy esetleg egy jó flash tartalma?A main board száma:T.MT5310.S97A.Sikerült egy jó flash tartalmat letölteni így jó lett a tv!Lezárva
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?
