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:

Pfaff 807 varrógép ZAVARSZŰRŐ csere 4+2 kivezetés
Sziasztok! adott a képen látható mechanikailag szuper állapotban levő Pfaff hobbymatic 807 varrógép 1982-ből.

Elpukkant a belső kondi rajta. 4 éve ugyanezzel már javítva volt szervizben. Akkor nem faggattam a szerelőt, h pontosan hogy lett javítva. Amit nem értek, hogy látok benne egy szintén megkímélt állapotú motor egységet, rajta egy kondenzátorral ami viszont tuti nem új.

Kérdésem,
  • Lehet a szerelő úgy javította, hogy az egész motort cserélte egy jó állapotú bontottra?
  • ez egy 6 kivezetéses kondenzátor, mondjuk annyit látok hogy az egyik a testre van kötve.. honnan lehet ilyen kondenzátort szerezni?
  • az, hogy egy kondenzátor hat kivezetéses, még több fajta elrendezést takarhat..? pl miflex-nél egyfajta 6os van.

Ja meg hát ami a lényeg, hogy lehet ezt megcsinálni? :D

új kondenzátort szeretnék, mert mindkét alkalommal a lehető legrosszabbkor ment tönkre. Ezúttal megbízhatóra szeretném.




tippeket köszönöm :)
