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

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
