PHILIPS 32PW6506/01 tipusu készülék EW hiba MEGOLDVA
Sziasztok ! Segitséget szeretnék kérni a fent jelzett TV-vel kapcsolatban . A készülék nem működött amikor hozzám került . A tulaj elmondása szerint mielőtt tönkrement a kép - szemböl nézve - jobb oldala EW hibára jellemző módon beszükült . Sorvégtranzisztor (BU4508DF) csere után elindult , a jelzett hiba jelentkezett majd egy perc után megszünt . Ezután kb. egy órán keresztül tökéletesen működött . Egy ki-be kapcsolás után ismét jelentkezett de már szinte állandó jelleggel . Ekkor a sorvég- tranzisztor hűtőbordája forró volt . Elképzelésem sincs hogy mi okozhat ilyen hibát. Várom a tapasztaltabb kollágák segitségét ! Üdv. gabicsizi
Philips 50PUS6503/12 kijelzőhiba?
Jó Estét Kollégák!

Az ügyfélnek 2 db ugyanilyen tévéje van.Az egyiken függőlegesen néhány csík látható.
Valószínűleg kijelzőhiba.A másik a mellékletben lévő hibát produkálja.
Megkímélném magam a felesleges munkától...?
Mi a véleményetek?
Köszönöm,üdv,kovi
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.
