Sziasztok.
Az a gondom ezzel a szerkezettel hogy nem akar jó szívvel indulni. Ha röviden nyomom a csatorna gombot csak egyet pislog és nem indul. Ha hosszan lenyomva tartom elindul és utána jól megy. Kondikra gyanakodtam de nem igazán jöttem rá a hibára. Valakinek esetleg volt hasonló problémája?
Sziasztok
Adott egy TV.. Adott egy Panasonic tx-32lmd70 tv chassis: GLP22
Angliából való.. Sajnos emiatt csak UHF-en működik, I hanggal.. Nekem ugye értelemszerűen Kellene a VHF és az S sáv iss, BG DK hanggal.. A TX-32LMD70F az europai piacra van, az tud mindent.. A 2 tv 100%-ban megegyezik, ugyan az a tuner stb... Valószínű softver vagy eeprom a különbség.. Valaki tud segíteni? tx32mld70f eeprom tartalommal? Vagy bármiféle segítséggel? Sajna így a TV nem használható ::(
ELőre is köszi
Laci

This elderly monster arrived with the error “ 4 blinks “ which the manual suggests is a power board fault
There are TWO power boards and a standby power board inside
On removing rear cover there were two swollen 220uf caps on the standby board, sadly replacing them the 4 blinks remained
Swapping the two power boards over[ as they look identical , gives a “ 2 Blink “ error , the limited info in the manual suggesting that the fault is on the lower board [ main 2 ]
Both boards have a PFC voltage of around 380 volts at switch on before the relays click out
I have done cold checks on both boards and there are no obvious differences
As the manual has only a block diagram of the power supply it’s difficult to be sure of values / voltages
Has anybody seen or worked one of these or similar beasts and managed to diagnose the problem
Thanks for looking
Regards Ken
