Sziasztok
Egy ismerosom kerdezett egy ilyen TV-rol:
Philips 46PDL8908S-12
Azt mondta alaplap kell bele. Kerdem, miert olyan biztos, hogy alaplap, es mit csinal?
Mondja, hogy amikor kinyitottak, SMD kondik voltak lepotyogva a proci korul es "7-es hibat ad".
Nem tudom, hogy a LED pislogasara gondol, vagy mas hiba?
Szerintetek ez egy tulmelegedett proci es menthetetlen? Vagy meg lehet menteni az alaplapot? Ha jol tudom, QFU1.2E van benne.
Minden jot,
Janos

Üdv!
Ma érkezett a fenti tv, amelynek a képe pirosas lett. A katódokat 100k-val testelve nem jön elő a zöld. Valószínűleg csőhibás lehet?
Philips 42PFL3605/12 won't start.
This is TPM4.1 ELA chassis.
DC-DC converter U7106 (G973-120) is faulty, Replace with BA033T or similar.
Footprint might be different but as long as a 3,3 V low drop stabilizer ic, approx. 1A output capability is used it will work.
Pin 3&4 from the U7106 is 3,3V outputpin 5 & 6 is aprox. 5,2 V input.
Mind you: The botom of the case of the original U7106 is also soldered to mainboard.
U7106 can be found on the right side of the mainboard next to the metal case on the mainboard.
To check if this is indeed the problem, measure at pin 3 & 4 for always 3,3V, if defective the voltage will be somewere around 1,2 V .
Then the set will not start.
Üdv!
Lenne egy ilyen tv.
Ilyen zöld a kép, és néha kimerevedik, törik.
Lehet ezzel valamit kezdeni?
Kösz
p.s.
Most meg lila... Ez valami kijelző gond lesz...??
