Cześć

Mam problem z rozgryzieniem usterki Dell'a o modelu jak w temacie , komputer się włącza, klawiaturę podświetla , reaguje na przycisk, niestety nie daje obrazu.

Pomiary podstawowe nie wykazały ani braku napięcia na cewkach ani też zaniżonej oporności.

A mianowicie:

PL5101 - 1.2V / 90Ω
PL4551 - 5.1V / 50kΩ
PL4501 - 3.3V /5kΩ
PL4401 - 13.1V / 51kΩ
PL4701 - 0.7V / 7.2Ω
PL4702 - 0,7V /7.2Ω
PL4801 - 0,65V /15,2Ω
PL5401 - 1,79V /4,8kΩ

Zasilanie na złącze matrycy 13v dochodzi
BIOS - naprawiany ale nie programowany nowymi wsadami ponieważ nie znalazłem.
Czy to kolejna ofiara AMD Ryzen ? Bo wszystko mi na to wskazuje.

Podaj dokładne oznaczenie płyty głównej, bo brakuje oznaczeń do jednoznacznej identyfikacji MB.

Zacznij od wrzucenia BIOSa, niestety często na tych płytach jak się sypie CPU, to wrzuca krzaki w BIOS. Jeśli zadziała, potestuj go z 3 dni, bo problem lubi szybko wrócić.

Dokładne oznaczenie płyty to:

Cyborg 15V AMD A00
203099-1
WMFJ3$CA

BIOS znalazłem programowany jednak na każdym wsadzie jaki znalazłem niestety nie uruchamia się ale objawy są inne tzn. mryga klawiatura, inne pobory, wiatrak nie startuje.
