Mindenkinek.Egy Lapauw ipari mosogep LCD kijelzojenek nem megy a hatter vilagitasa azt igy nagyon nehez programozni. Szet szedtem, megneztem es ferfiasan bevallom, ha meg egy ilyet latok az lesz a masodik. Egy kis traforol (talan inverter ) megy ket vezetek es a kijelzo alatt lehet ami vilagit. Azt kerdeznem hogy ezek a kijelzok egybe vannak epitve a hattervilagitassal, vagy kulon cserelheto. Sok idot nem tudtam vele foglalkozni, mert ment a termeles (mosas ) es majd a hetvegen tudom jobban szetszedni, de jo volna valami info az ilyen kijelzokrol. Van a birtokomban egy ilyen tablet (Flytouch 2) Android 4.0 rendszerrel. Kerdesem az lenne, hogyan tudom lementeni (dumpolni) a rendszert? 2 okbol is kellene:Vagyis szeretnek rajta is segiteni, illetve nekem is jo lenne egy biztonsagi mentes. Rengeteg oldalt vegigolvastam (ROM dump, superuser, root-olas, stb), de eddig semmi hasznalhato. Ha valaki otthon van ebben, vagy mar csinalt ilyet, legyen szives segitsen. Letoltott ROM-ot tudok felrakni, de neten csak kisebb verzioszammal erhetok el. Ha sikerulne lementenem, szivesen kozkincse teszem itt a tanyan is, biztos sokan fel tudjak hasznalni.

Hidegen nagy ellenallasanak kell, hogy legyen, es melegen kicsinek. Emlekszem, hogy a vizmelegitoben a termoelem melle volt beteve meg egy erzekelo, csak mar nem emlekszem, hogy az micsoda volt.

FOREWORD For your convenience, all service parts, identified in this manual are available through Eiki’s normal distribution channels. Primary side of the converter and lamp power supply unit circuit is connected to the AC line and it is hot, which hot circuit is identified with the line ( ) in the schematic diagram. For continued product safety and protection of personnel injury, servicing should be made with qualified personnel. The following precautions must be observed. Relay lens-out adjustment. If the abnormality occurs inside the projector, it will automatically turn off by operating one of the following protection circuits. ? Fuse The fuse is located inside of the projector. When either the LAMP Fuse indicator or the READY indicator is not illuminated, fuse may be opened. Check the fuse as following steps. Page 7 Circuit Protections. Warning temperature and power failure protection The TEMP WARNING indicator flashes red and the projector will automatically turn off when the internal temperature of the projector exceeds the normal temperature or when stopping cooling fans or when the internal power supply lines are failed.http://schlammatlas.de/en/node/21692 Check the following possible causes and wait until stopping the TEMP WARNING indicator flashing. Possible causes - Air filter is clogged with dust particles. Following steps show the basic procedures, therefore unnecessary step may be ignored. Caution: The parts and screws should be placed exactly the same position as the original otherwise it may cause loss of performance and product safety. 1 Cabinet Top and Control Panel removal 1 Remove 4 screws A to take the Cabinet Top Ass’y upward off.
