#1 Monitor Iiyama ProLite X2483HSU brak podświetlenia

Płyta główna 4H.26N01.A12
Zasilacz 4H.28102.A02
Monitor startuje, widać pod światło treść ale nie ma podświetlenia. Sprawdziłem złącze CN861 i na 3 oraz 4 pinie mam 24V, na reszcie 0V. Te napięcia wychodzą z układu MPS1526. Czy 3 i 4 pin to zasilanie podświetlenia LED matrycy? Jeśli tak to bardzo możliwe, że uszkodzona jest jakaś dioda w podświetleniu bo podłączyłem pod zasilacz serwisowy czerwone kable jako + a czarny jako - i nie było żadnego poboru prądu. Ewentualnie jak inaczej mogę sprawdzić podświetlenie bez rozbierania matrycy?
