LG PF1000U Ultra Short Throw Projector (chassis FM51E) Firmware
Good afternoon!

I'm looking for a dump for the LG PF1000U projector (chassis FM51E), (NAND Hynix H27U1G8F2CTR SPI_FLASH: MX25L8035EM2I, EPROM 24C256C).

There is no epk file available anywhere :( 

This device attempts to turn on and responds to both buttons and the remote control:

It exits standby, runs the fans for 5 seconds, then spins them at 100% for another 5 seconds judging by the sound, and then goes back into standby.

The problem seems to be a corrupted NAND as it appears to me:

Bluetootos fülhallgató csak az egyik szól
Kérem DINO54 ne szóljon a témához!

Sziasztok!

Lenne egy ilyen ketyere :
https://www.ebay.com/itm/i7S-Bluetooth-Mini-Earbuds-Earphone-TWS-Wireless-Universal-with-Mic-Charging-Box/332724567038?hash=item4d77edfbfe%3Ag%3AkIgAAOSwxrpbVZr4&LH_PrefLoc=6&_sacat=0&_nkw=I7s%2FI7s+Plus+TWS+Wireless+Bluetooth+Earbuds+&LH_BIN=1&_from=R40&rt=nc

Csatlakozik is a telefonhoz, mind a két fele, de csak az szól, amelyik utoljára bemondja, hogy "az eszköz csatlakozott". Mi lehet? Van Valakinek tapasztalata ez ügyben?
Köszi.

Aszt szeretnem ha valakinek van ijen fülhalgatoja ha megmérné a elenalasát.
Mert csalódotam a elenalása 47ohm es a impedancia 57ohm

GK-600 vezetél nélküli fejhallgató (megoldva)
Sziasztok! Egy másik listán már feltettem ezt a kérdést, sajnos nemsok válasz érkezett :-( Megpróbálom it is... hátha... Van nekem egy gagyi GK-600 (kinai) vezetéknélküli fejhallgatóm. A bele majdnem pontosan így néz ki: http://www.circuits.8m.com/Fm-radio.htm Itt mindjárt e legfelső varicap hangolású rajz. Annyi a különbség, hogy nálam még a bemenet és az antenna között van egy sima földelt emiteres erősítő 1 tranzisztorra. (bázisra kondin keresztül antennajel, és a kollektorról egy kondin át az IC bemenetére.) A szűrő már ugyan az ami a rajzon. A problémám. Bekapcsolás után nem találja meg az adó oldalát, és az egyéb FM adókat. Most jön a csavar. Ha LEKÖTÖM a kb. 20 cm-es botantennát, akkor minden adó előkerül, és működik. Természetesen így nincs "tartaléka" ezért mozgásra elmászik, illetve kicsit zajos a hangja (gondolom az FM limiter még nem él.) Az elkókat cseréltem benne. Aki jobban ért a nagyfrekihez kérem súgjon nekem pár tippet. Itt van egy kép róla: http://img.diytrade.com/cdimg/410919/3642059/0/1179360571/Wireless_Headphone_GK-600.jpg
