Compared with TC-T7-H, it has upgraded circuit structure" (prawdziwa??)Atmega644p, 16Mhz ma port programowania Oczywiście pierwsze co zrobiłem to skompilowałem i wgrałem najnowszy 7.10. Multifunktionstester TC-1 and family (T7) with ATmega324/644 (very poor...

TV works for 1 or two second, sometimes half minute, picture is normal, temperature of BU is normal. But it goes defective without a bang, the tv just silently switches off and Bu is defective. C524, c 527 had low capacity, was replaced but the fault persist. Also replaced line driver transistors.
Mam to: Adjustment procedure for 16:9 TV sets General The adjustments of the receiver are performed with a remote control handset. Only focus and G2 adjustments are potentiomter adjustments. The settings have been distributed among 16 adjustment planes. The usual colour and geometry adjustment routines are performed in 5 adjustment groups on adjustment...
Hello friend, I came across your post while looking for images of the spark unit 2PU6098-4107P1 4 by OKI that came with my 2002 Honda Deauville. While my spark unit is in fine working order as I managed to start the motor on the bench without the bike and all of its systems attached I wanted to share a bit how I did it which may help you do the same....

A czy mógł by mi ktokolwiek odpowiedzieć czy układ ROM ( U401 - na dyskach ATA ) ( U200 - na dyskach SATA ) ma jakiś wpływ np. czy zawiera w sobie informacje o układzie i ilości głowic lub podobne ważne informacje, do działania dysku? http://obrazki.elektroda.net/44_12264953... http://obrazki.elektroda.net/26_12265055...

1) Nie pojmujesz rodzaju uszkodzenia ( bardzo skrótowo - Uszkodzenie fizyczne, a nie logiczne) 2) Odzysk danych w takim wypadku nie jest łatwy ale przywrócenie Pena do życia może być łatwiejsze niestety dane wtedy stracisz ( I nie chodzi tu o format). 3) Formatowanie obecnie nie tylko nadpisze MBR. Jeśli to NTFS a Format jest szybki to co najmniej jest...
Sprawdź trafa wn. w pierwszej kolejności.Mogą być uszkodzone świetlówki i również powodować takie objawy jak u ciebie. OK - sprawdzę. Skoro masz multimetr Brymen i umiesz mierzyć, to rozumiem, że sprawdziłeś napięcia wychodzące z zasilacza? nie - generalnie pracowałem nad nim "offline" bez prądu. Nie wiedziałem jakie tam napiecia mają być nie majac...
sekcje zasilania led mają dodatkowe przetwornice step-up podbijające napięcie z 37VDC (wstępnego stałego zasilacza) do 68VDC w celu regulowania podświetlaniem. Jakie tam są układy zastosowane? P.s LK400D3LA43 code 225. Z tego co mozna wyczytać to drugi zasialcz dla LED wykonano na 3843 + polowe AOD454. Podają takze ,że rozwiazanie z dwoma zasilaczami...
Panowie ponownie proszę o pomoc. Nie mogę sobie poradzić z kodem. Przerabiam,kod ze strony: https://randomnerdtutorials.com/esp8266-... Niby nic skomplikowanego, a jednak.

Czy ktoś miał kiedyś takie problemy że przy zaniku napięcia sterownik stracił wartości Actual Value, czy to jest dolegliwość siemensa mimo zastosowania drogich kart pamięci.
