Sony KV-29K1D sípol
Helló! Bekapcsoláskor olyan kb 1 KHz-s hangot ad, majd melegedés után ha kihúzom és újra bekapcsolom akkor megszűnik a hang és utána már szépen működik. Ez egy 2 tuneres PIP-es készülék és ez az érdekesség benne, ha lehúzom a másik tuner panelját és úgy dugom be hidegen akkor nem mindig csinálja. A tunert már cseréltem a panelokat kielkóztam, tápok mérve jók, jellemzően nem mutat a szkóp rajta szűretlenséget. Volt már vkinek hasonló hibája? Üdv.: Ízirájder
Sony KDL40R485B TV újraindulgat
Sziasztok,

A címben szereplő TV bekapcsolás után mutatja a logót, majd újraindul és folyamatosan ezt csinálja.
Gondolom szoftverezni kellene, ehhez kérnék segítséget.
 - Honnan lehet letölteni a hozzá való szoftvert?
 - Elég egy pendrive-ra rárakni és onnan elindul, vagy direktbe kell programozni a chip-et?

Köszi!
