Made some good progress, but there seems to be a sync problem.
I posted to the EEV blog for more help:

Any help or feedback appreciated.
Sziasztok!
Tárgybéli készülékben a nyáron sorvégtranyót cseréltek, eddig bírta. Az eredetije 2SD1441Rl, S2000-et tettek bele. Ez utóbbiban nincs dióda, szerintem abba halt bele. Mit tegyek bele?
Amúgy induláskor homályos a képe, be kell melegednie, hogy jól működjön, de a szervizben ezzel a hibával nem foglalkoztak.. Szerintem egy átkondizás jót fog tenni neki, bár eléggé újnak tűnnek, ESR mérőm meg nincs..
Üdv: Jácint
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!
A címben írt TV-n egyik napról a másikra megszűnt a vétel.
A helyi szolgáltatónak HWG eszközén keresztül lehetséges a DVB-C vétel.
Az eszköz jó mert egy LG megtalálja az adókat.
Alaphelyzetbe állítás megvolt, akkor felkínálja a szolgáltató választást (Digi/upc). Aztán ez az opció elérhetetlen.
A tv a tunerre azt mondja rendben van.
Minden egyéb funkció működik.
Analógon megtalálja azt a pár adót.
Lehet mégis tuner gond?
Köszi a segítséget.
Megoldás:
Régiónak Finnország lett beállítva.
Azon belül egyéb.
Majd teljes keresés.
Köszi mindenkinek a segítséget.
