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:

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.

Sziasztok!
Van egy inverteres LG klímám ami kommunikációs hibával megállt. Jobban megvizsgálva, a kültéri egység szerint F27es hiba, azaz a PSC hiba, azaz (Prospective short circuit (PSC) fault error; current to inverter compressor between
AC and DC converter circuit is too high) . A szervízrajz egyértelműen rámutat azokra az alkatrészekre amelyek hibásak lehetnek
és mérés után, valóban hibásak, zárlatosak is.
Ennek az áramkörnek a szerepére nem tudtam rájönni, mivel az AC L és az AC N hálózati feszültséget az egyik greatz irányítja és megy is tovább a inverter felé a másik greatz híd árama pedig egy IGBT. hez csatlakozik, mellyel a híd +,- polusait lehet" zárlatba" kapcsolgatni? Ez valami fázisjavító áramkör lehet, vagy mi a fene? A TLP251 egy optócsatolós meghajtóval van kivezérelve az IGBT, az optocsatolót meg a processzor vezérli a PSC on-off jellel.A tárgyalt áramköri részt pirossal jelöltem. Segítségeteket köszönöm előre is!

Sziasztok!
Segítségre lenne szükségem.A fent nevezett töltőt bedugtam,hogy töltöm az akkukat de nem történt semmi.Csak ciripelést hallani.Szétszerelés után láttam,hogy kapcsolóüzemű táp van benne.Szükségem lenne kapcsolási rajzra vagy tanácsra,hogy mit cseréljek.Púpos kondikat nem láttam.
Előre is köszönöm.
