Philips 42PFL3605 chassis TMP 4.1 won't start
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 Mindenkinek! Kaptam egy ilyen TV-t, azt produkálja, hogy bekapcsolás után a beállított csatornák működnek, de nem lehet programozni sem, illetve hangerőt is csak a select gomb megnyomásával lehet változtatni. Ha már kiválasztottam a select-el a hangerőt, akkor reagál a táv hangerő + és - gombjára is. Ha valakinek van valami ötlete, kérem ossza meg velem... Előre is köszönöm. Üdv. Mlacidb.
PHILIPS 24PHS4031/12 BURN IN MODE KIIKTATÁSA
Tisztelt kolegák,

a címben adott tv begurult ebbe a mókuskerékbe és folyamatossan átkapcsolgatja a színeket. Mi a megoldás? Van-e nyomógomb kombináció, távirányítos kód vagy új firmware beírása üti ki ezt a helyzetet.

üdvözletem
