LG Klíma vezérlő PTC Biztosíték beazonosításához segítséget kérnék
Sziasztok. Segítséget szeretnék kérni hátha valaki már találkozott ezzel vagy hasonló alkatrésszel. Szóval adott egy LG Multisplit Klíma vezérlő. Ezen a vezérlőn van a készenléti tápegység PTC biztosítéka ami tönkrement. Csakhogy sem az alkatrészt sem a gyártót és az értékét sem sikerült kideríteni. A PTC-nek van egy hőálló bakelit tokja amibe be van csúsztatva egy 14mmm átmérőjű 3mm vastag gombelemre elékeztető betét. A fedélen a felirat felső sor.: 400X Alsó sor.:KSR12 Behelyettesíteni csak akkor szeretném ha biztosan nem lehet beazonosítani mivel a vezérlő tápja elég rafináltan, szerintem feleslegesen bonyolultan működik. Ugyanis a PTC a teljes főáramba van bekötve ha a klíma bekapcsol abban az esetben van vele párhuzamosan egy relé, ami ha meghúz megkerüli a biztosítékot és az áramot pedig egy mérőtranszformátoron keresztül méri (Borzalmasan agyonbonyolított) Szóval megköszönném ha valakinek lenne ötlete ezzel a ptc-vel kapcsolatban. Kép mellékelve. Köszönöm
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:

Sziasztok! Nincsen valakinek véletlenül M21 -es Volga csöves rádió kapcsolási rajza? köszi: Laci
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.
