Sziasztok! Olyan hibával hozzták ezt a készüléket,hogy nem csinál semmit csak villog a stby led!A táp részét rendbe raktam meg a TDA 1521-et is cserélni kellett,főleg az okozta a galibát.Utánna kiderült,hogy a fénypont kioltása se tökéletes! De még hibából nem elég ennyi,visszintesen vannak benne csíkok,nem szabályosan helyezkednek el(nem visszafutás csíkok).Erősebb adónál nem annyira feltűnő,de gyengéknél nagyon zavaró!Ha külső videójelet kap akkor is jelentkezik!Olyan mintha vmi zajos lenne!Tudtok erre vmi ötletet adni? A hangnormát lehet szervizmenüből váltani?Vagy inkább 1Mhz rákeverő és kész? Köszi előre is az infókat! Üdv. Miki

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.
