6V/105A lúgos akksi
Üdv Mindenkinek! 6V/105 A-es lúgos akksit szeretne egyik ismerősöm újra lúgozni. Beszerezte a lúg tablettákat, de a keverési arány (tabletta+deszt. víz) nem ismert. Ehhez kérné(n)k segítséget. Előre is köszönöm:FEJO
Műholdvevő
Üdv mindenkinek! OPTICUM vagy GLOBO vagy ORTON 4100C hez kelene kapcs rajz. Illetve szervíz tipp.A készülék működik,de a függő szinkron bizonytalan.Néha meg fut a kép egyébként egy kis brumm látható az OSD-s kép szélén.Amit megfigyeltem még:a tunerről le volt lazulva a nyák felöli burkolat és valószinű hozzá is érhetett a hozzá nagyon közel lévő SMD kondikhoz vagy ellenáláshoz.Az egyik szerintem le is tört C52 pozíciószámú.(e miatt kellene a rajz)A tápból semilyen brumm nem érkezik a tuner környékén sem mértem brummot.A kondikat kimértem (komponent teszterrel is)egy sem kapacitás szegény.A kitört kondi helyére próbáltam berakni különböző értékeket de semmit nem reagált
Philips micro theatre MCD 288
Sziasztok! Segítséget kérnék ismét. Adott ez a kis "szörmedvény" ami füst jelekkel kommunikál. Sajna nem vagyok apacs, sem dakota indián, így nem értek belőle sokat. Az viszont tény, hogy a trafó füstöl, nem is kicsit. Toroid trafó található benne, sajnos minden jelölés nélkül. Talán megérne egy cserét, de így nem tudom milyen kell bele. Ha esetleg lenne valakinek rajza hozzá, vagy ismerné ezt a készüléket, kérem segítsen. Üdvözlettel: Z. Elszállt a füst és kiszedve a panelt, fény derült az értékekre.
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:
