TV LCD Philips 37pfl8404h/12 nu porneste .


Recommended Posts

Buna!

Am un Tv lcd Philips 37pfl8404h/12 care nu porneste.

Sasiul este q548.1E LA si sursa delta dps-298cp.

Practic palpaie ledul cateva ori dupa care porneste neoanele de trei ori si se stinge (desigur tot de 3 ori :-))

In timpul acesta displayul este negru.

Practic am citit erorile (cu compair) si apare 17 (inverter or display supply ) si 21 (eroare PNX5100 )

Ma gandesc ca eroarea la PNX apare din cauza unui update de software nereusit.

Dar la sursa nu vad ce ar fi deoarece powerOk pare a fi in regula (mai trebuie sa mai verific).

Am schimbat toti condensatorii electrolitici preventiv (in afara de cel mare la 450v) dar desigur ca face la fel (e prea nou tv-ul).

Update am facut prin hpertrerminalul windowsului (numai asa poti vedea ce si cum) dar vad ca la fel.......nimic ...ramane sa incerc alte softuri de update.

Tv-ul nu intra sub nici o forma in stand-by ....se restarteaza practic mereu.

Are careva o schema a alimentatorului ? (are invertorul incorporat)

Sau gasesc pe undeva placa principala la un pret rezonabil (nu ma refer la "aduc noua la 150euro") :-).

Astept sugestii

Multumesc

ps:am schema :-)
